Tried to start an HD-5G that I bought. It had been sitting for a number of years. Changed oil, drained all fuel, new filters, purged lines, new injectors, etc. in preparation for starting. Timed injectors, etc.
Put propane heater in barn where HD-5 is and gut temps up in good shape.
Engine cranks great, puts out quite a bit of smoke and is just on the brink of starting. It runs for probably 3 seconds after the starter kicks out and dies.
It acts like timing may still be off, but I don't know what it would be. I confirmed there is good air flow through the blower. On my old TD-18, it kind of sputters like this but then kicks in and kind of cleans itself out. I don't think the 2-71 has any valve train advance---or does it?
Suggestions are appreciated.

Roger, sounds to me like the compression is down,but maybe all is not lost.I find that engines that have rested for quite a while and were not in perfect health anyway are hard to start the first time, but if you can get it running for a little while, a healing takes place.I think the sealing oil film on rings and cylinders goes away, then we add a little crud between valves and seats so they leak a little, then we let the oil thicken including the hyd. oil, and the poor old starter just can't spin it fast enough to light the fire.
I have started several balky diesels for the first time in a long time by feeding them a bit of lube oil.Not enough to hydrostatic lock the engine.It actually seems to be more effective than starting fluid in establishing the first light off.
Turning the engine faster will help but often must be done by pushing or pulling the machine.You will be surprised how little movement at a brisk rate will start that engine with lowered compression.The leaks don't have time to hurt you.
I think the best way to oil the cylinders on a
jimmy might be through the air box inspection holes with pistons on the bottom.Can't say as I've done this trick on a jimmy.
Starting fluid tends to wash the oil film away so it can work against you.Good luck.

   By rodger ( on Monday, January 15, 2001 - 8:51 pm:

I should have added that when I gave it a shot of starting fluid, it acted like it was getting too much compression---and didn't fire. Yet, after it got the starting fluid blown out, it did act like it wanted to start on the regular diesel. My normal experience with ether is that it causes the engine to fire easily. It acted almost the reverse with the 2-71

   By JD ( on Tuesday, January 16, 2001 - 10:48 am:

Something that I have used to start engines that works fair and may work for you is WD-40 just remove the air filter and apply it like any other staring fluid .

How much is a Allis Chalmers H-3 or HD-3 crawler/loader worth these days? It's been gone through with a fine tooth comb, and is in great working condition.

   By bill ( on Tuesday, February 06, 2001 - 9:37 am:

If the UC is in as great a shape and run as well as you say it does, it should go for 5-10K for the machine and that is on the lower side of the value scale. Comparable sized machines from other non-Cat vendors have been ranging between 12-20K that there are some that are way lower than that too.

The value will be in the condition of the Undercarriage. If has been that well maintained you a price premium may be warranted since you are more likely than not, not to have problems for a long time. Again abuse ect can cut short the life of any machine. I would look for the higher side if it is as cherry as you say. It is a nice small crawler, very good size for acreage guys and small enought to haul around with out needing a huge semi and special hauling permits. They were also closer to the end of the production line for AC so some parts are still out there for the machine that is new.

A great project tractor and you should be able to resell it for what you have in it assuming it does not get ruined, economy fails ... all the rest of the stuff that affects value.

Good Luck

Hi every one! I am looking at a AC model M dozer with blade 1500$ I also may have found two parts model M's for 700$ question, How are these dozers for working, are they as good has a D2 of the same year. also how are parts to find. I did a search on this board and couldn't find any info. Any help would be very much appreicated. Thanks Duane

   By D2Tom ( on Sunday, May 27, 2001 - 1:03 am:

Years ago I ran a Model M pulling a 6'9 disc working the same field as a 5U D2 pulling the same size disc. They were about equal in performance.

As far as dozing, I think the M is a little lighter than a D2. I have seen them fitted with big heavy dozers. This extra weight might help. First gear is a little fast. It might be a little tricky to learn to operate, but it should move just as much dirt as a D2.

Buy the parts tractors too. Do any of them have electric starters?

i looked at an old allis chalmers yesterday, the owner told me that it dies after about 10 minutes of running, i think he told me it was a 655 1974 or 75 model. I know nothing about these allis chalmers... now with my experience i would say that the fuel return is plugged up, i told him to replace all fuel lines up to the fuel pump. i am hoping that the fuel pump didnt die on this guy, but that could possibly be the problem too, the pads chains and rollers are shot as well as the track adjustment on the left side is there anyplace near new york that sells cheap u/c part i know of that itm out of NJ i think that that is who i will recommend but first things first i need to straighten the engine out for him- thanks in advance

HD5G fan belt sizes. Anyone know the size on the 2 fan belts?

   By Lee Wise ( on Tuesday, June 04, 2002 - 1:28 am:

Please help,

I buoght a HD21P with a 12 foot u blade and a tr21 ripper about a month ago. The undercarriage is in good shape. New shoes, chain, grousers, rollers, sprockets, and idlers. I also got quite a few spare parts, and in general am very happy with it.

Now, to my problems:

First trouble I am having is if I run it at anything over about half throttle it starts to heat up. I have pulled the radiator and had it rodded, pulled and tested the thermostats, rebuilt the waterpump, and checked the cooling system for combustion gasses etc. IT STILL OVERHEATS!

Next problem is when I got the tractor, it had an extra 12 volt battery installed to run an electric fuel pump. As I understand it, the fuel pump is supposed to run at about 30 to 60 pounds of fuel pressure. The excess fuel being supplied from the injector pump through a reduced orifice to the torque converter, then to a heat exchanger and then returned to the tank. Thinking this might be part of my heating problem, I rebuilt the mechanical pump and got it operating, but i still show very little fuel pressure an the guage on dash, but have very good flow back to the tank in the return line. Also, the books I have show a fuel pump that is driven off the accessory drive, a gear type pump, mine is driven directly off the injector pump. My pump is cam driven and is a piston type pump. The more I read and investigate the more confused I get.

If anyone can shed some light on these problems, please help. Thanks for reading my ramblings, and for any help.

   By HD5 rookie ( on Saturday, January 04, 2003 - 6:10 pm:

HD5 runs for first time in years. Ive never heard this engine run before. It sound like it has a knock but also sounds like diesel kackle. I put a steel rod against the engine in different places while pressing it against my ear. I could not hear a clear knock. But stand next to the machine and I hear a knock. Does the 2-71 make such noises normally?

   By drott ( on Saturday, January 04, 2003 - 9:10 pm:

No normally they do not make a knock, they normally sound like they are wound up and going to beat the band. The 271 is a two stroke engine.

When they are cold they are a bit noiser, Detroits of that vintage are very cold blooded and can be noisy for quite a while till they get up to operating temperate.

One thing to do is to warm it up, take off all accessory belts ect. Then run the machine to see if the noise is still there. Make sure that it is not comming from the clutch housing and or the hydraulic pump. If you are short hudralic fluid and or the pump is going bad ou can get a clack noise out of them. Frozen water in lines can do that do in the pump. The pump is attached to a shaft on the crankshaft pully.

Once that is eliminated, change oil, put in new filters and see what happens. Now it is easy to drop the pan off the engine and see how bad the gunk is and if there is any metal in the engine.

The noise could be from a fuel pump going bad, the rotors on the blower are hitting which can happen and that is expensive to fix if you ruin the lobs on the blower.

The first place to look at is pre detonation of the fuel and or the file rack is out of adjustment on that engine as to timing and amount of fuel getting to the cylines. Now that engine has the injectors and control rack in the head. The injectors are available as a reman. You just need to know the knozel tip size. Make sure that the nozel tip is clean and clear

Hope that helps.

   By HD5 rookie ( on Sunday, January 05, 2003 - 10:01 am:

Thanks for the info I will check all of the possibilities.

I did notice the engine never got hot enough to keep me from touching the head with my bear hand!

I will replace the thermostat and run it again til it gets hot! Hopefully that will cut down some of the smoke too ( stuck rings unburnt fuel)

I do have fresh filters, oil and anti freeze in it.
Also reman injectors and rebuilt blower, lapped valves. I dis-assembled the fuel pump and freed it up. It had locked up due to rust. It did not show much wear so I polished everything and replaced the drive coupling.

I have also had the pan off. It was full of sludge but I didn’t really see any metal. I replaced the rod bearing caps because the crank measured high limit on clearance. I just saw (in the book) that the bottom half of the mains could have been replaced at that time....hind sight is 20/20

We have to replace the check out the trans,ring and pinion and re-install the steering clutches, check out the final drive gears etc. We have a spare machine with gears and motor. Our plan is to go through the whole machine get it to function, run it awhile then rebuild the engine. Right now were just glad she runs!

broken. The shaft is broke. I have a used shaft. The used shaft has only 1 nut on the end. My question is. What keeps this shaft in the final
drive? It looks like if I pull off the outboard bearing and drill and tap a hole in the end of the broken shaft it would pull out leaving the
bearings gear etc, in the housing. Is this correct..The book talks about
dis assembling the finals but not just replacing this shaft..

I just bought an HD7 and it was delivered today. The fella said the left clutch was sticking a bit. I guess that was only the tip of the iceberg. Please don't laugh at my obvious newness. I'm used to wheel tractors. I can't get the crawler to turn at all, she did a bit but now won't. She moves forward and back fine. I pull the lever back, and that side stops. Pull the left lever and push the left pedal, she just stops and hitches and shudders. Pull both levers back, dead stop. Read elsewhere about push on a tree to work things loose, left track stops, right track digs in. Did I get a basket case or do I just need to learn about and do some adjustments? Thanks for any and all help!

I bought an HD7W dozer. Runs and steers great! U/C has 2 bad rollers I mean BAD! the shafts are half worn thru. I have made new shafts have the bearings and new seals on order..

My problem is the right rear axle. I think because the rollers ( also on the right side) were bad and the block and bushing that attaches the rear mount of the blade was also sloppy the axle broke. I got a new axle as part of the deal. Right now I am trying to remove the old axle. I have a book but it does not tell you much about the axle. I have the final drive gear and housing off. I also have the cover off of the bevel gear housing. I can see both ends of the axle and I have removed a set screw that holds it in.
So far I have welded a 1"-8 nut on the broken end and have tried using a jack screw to pull the shaft out. I hasen't budged. My next idea was to put a porta-power or bottle jack inside the bevel gear housing and try and push the axle out.

Anybody else ever remove one of these axles?

I have a 1966 A/C HD7G Crawler loader. Everything seemed fine until one day I went out to run it & it wouldnt move in high gear forward & reverse. In low gear foward & reverse it will barely move, hardly enough power to move itself. When I parked it the day before it was running fine. Any suggestions were to start trouble shooting this problem.

HD 6 PTO question:

My dad has an HD6 crawler, recent acquisition. He wants to run his Belsaw sawmill (540 rpm, shaft drive) from a rear pto on the dozer. It used to have a hydraulic pump apparently, seller had a shaft manufactured that comes through a carrier in the back and turns a pump-driver gear box...ho-made pto basically but it's a 3/1 reduction and turns in the wrong direction. We need to know what the rpm the rear shaft would be turning at (straight thru?) and any suggestions on finding a stock pto unit for this machine? Thanks, dj

I am looking for information on an Allis HD16AC, serial #4197, 1959 model with torque converter and constant mesh tranny. The problem I am having is that when the hand clutch in disengaged the tranny will not stop completely to allow for shifting gears. It seems to be hanging up somewhere, and with the clutch inspection cover off, it makes a rattling sound. I have a service manual, but it doesn't cover the torque converter model very well, and I have adjusted the clutch to no avail. I am also looking for a onwers manual, and maybe a parts manul for this crawler too. Also, if anyone knows where there is a ROPS or cab for one of these, let me know. Thanks, Darrell, JR. (MN)

I use this little crawler here in New Mexico to do range and timber management to harvest trees and mill them. I make heavy furniture and this crawler is just perfect. I can't believe how strong the little guy is.

Looking for some help on an HD-5: My father has a 55 in need of some work. He does not have the tools to do this job himself so I figured I'd see if anyone near him can help. The spring on the adjustor will not push the idler back when the idler is forced rearward under pressure. This is what he thinks... He believes the idler bracket is either shimmed to tight or the shimms are rusted?? Basically if your making a turn under pressure the track will loosen up but will not return back to its normal position. He could do it by himself 40 years ago but not at this time. He is located in the Hartford Connecticut area. Any help would be appreciated.

I am rebuilding a dump cylinder from my Allis Chalmers HD-5.

It has a 2 part piston. V-ring in front part, bearing ring in back. The parts book shows the two parts tight together with a shim under the v-ring packing. (no instructions on how to set shims)

My question is how tight should I make the v-rings to the cylinder wall. I have new V-rings and no shim so I have to set it up from scratch! If I stack everything up finger tight I have about .125 gap between the two parts of the piston. When I slide the cylinder on, it rubs all around the cylinder wall but not tight.

I figure I'll tighen the the two parts until I'm satified with the fit then dis-assemble it and make a shim.

anybody ever rebuild one of these before??

How tight are new cylinders?

   By Hedrick ( on Wednesday, April 14, 2004 - 3:50 pm:

I was given an HD-9 by a friend of mine if I could get it out of his backyard. He was using it when the front idler bearings went out and the track came off and broke a link. The dozer belonged to his father and they got into an arguement over it. The dozer sat 12 years until the father passed away and they tried to sell it at auction. They didn't get any bids on it, so the son was going to cut it up for scrap. After he said I could have it, I put new fuel in it and two new batteries and it started right up. There was a stuck injector and it wanted to run full blast. I fixed that and my son and I worked for a couple of weeks off and on to put the track back on. The guy that gave it to me had new links, pins and bushings to fix the track. The father had already had the bearings fixed in the idler and it was in the garage waiting to be put on. The pics are of the dozer after I cleared the brush and cut down the tree that had grown up between the blade and dozer. I have since brought old girl home and have used it a few times. The only thing wrong with it now is a stuck left hand steering clutch. If anyone can help me on how to fix this, I would appreciate the info. I have already tried the paint thinner in the clutch technique and it hasn't worked. I will send in some more recent pics when I get them.

   By nutz-n-bolts ( on Thursday, April 15, 2004 - 3:11 pm:

Looks like you got a great deal. As for your clutch, it looks like you may have to pull it out. The solvent trick is the only one I know of and if that doesn't work you have to pull it. I just pulled mind from my HD5. It wasn't too bad. The hard part comes when you find out the prices for all those new disks you need, and look out if you have to replace the throw out bearing. Are you going to restore it?

   By hedrick ( on Thursday, April 15, 2004 - 4:49 pm:

I do plan on restoring it to a degree. I am going to repaint it, but this is a farm dozer and not a show piece. The engine seems to run well and starts everytime. Someone has put an alternator on it and it isn't working so I will probably replace it or have it fixed. I also can't get it into all of the gears. The hi/lo works and I can get it into two forward gears and two reverse, so it still works ok. I was pleased to see that the hitch pin and the hold down was sitll in place. I kind of assume that the tilt blade was added later or do you think that was factory installed ?

How many teeth are on the BENDIX of a starter for a 2-71 detroit?

The facts are confusing me.

Every reference I look at, for 2-71 states the starter has 11 teeth.

12 volt, 11 teeth CW rotation.
However, when I pulled mine, it had 12 teeth. And yes, it was starting fine.
11 teeth? 12 teeth?

The starter # in my book is Delco Remy 1109114. My starter is a 1109114.

So should I buy a 12 tooth replacement like the one in it or 11 tooth as every reference I can find on 2-71 units?

I currently puchased an HD-5. I am having some problems with the engine. It has the Detroit 2-71. Only one cylinder will initially fire ( I got injectors checked and both are in good shape). After about 5 minutes the other cylinder will start. The latest development is that it is blowing white smoke out of the exhaust and the crankcase. It is building up pressure in the crankcase. I thought maybe moisture getting in the engine from the head. I pulled the head and found one cylinder was rust color and the other black. The gasket was partially cracked in one spot and was installed backwards(I have no idea why, but one of the coolant ports was blocked because of this). I got a new gasket and installed it and there was no change in running condition. I would apppreciate any help with this problem.

I have an HD7g that won't turn. I have done some testing and am not getting pressure from the steering pumps. Steering pumps share a common sump with trans pump and torque convertor pump which both work. When I bought the crawler there was mickey-mouse setup on the sump line to prime the steering pump which the seller used to get the crawler to steer. This option does not work now. Any ideas or offers to buy would be greatly appreciated.

Does anybody know then AC started using the triangle shaped logo? I found a loader in a field and no house in sight. It is a 6 cylinder about the size of a International 175B. It is a power shift and has a roosamaster injection pump. I can't find a model number anywhere on it.
It has the triangle logo on the left side of the hood.

Trying to find an old crawler to rebuild. It doesnt need to be running, or even have a good engine. But at least complete from the trans to the tracks. It can be very rough but it should be under $1000 US dollars if it is really rough.
I can arrange transportation to rid you of that eyesore!

Hey Guys...recently purchased an old HD6 with only 1300 hours on the frame and about a hundred on the engine. Noticed that the right clutch takes a hugh amount of pressure to make it work and was wondering how to adjust it. The left seems to work very I'm thinking just adjustment. But maybe it'll need replacement. Can one still buy new clutch parts? Thanks in advance for any help!

I have an old Allis Chalmers HD-7 tracked dozer. Wondering about some basic questions and looking for some advice.

Does anyone know the years the HD-7 were made?

Who made the motors for the HD-7 Dozers? What is the HP rating?

What is the weight?

Did they ever come with winches, and if so, what was required to operate the winch?

When it was last parked, it did run, but I think we have a electrical problem. Its a positive to ground system. I'd like to get it back operational.

1. Can anyone describe the basic electrical ignition system for me so I can check to see if it works.

2. Can anyone suggest methods to wake the diesel engine. For instance with a gasoline engine, I would pour penetrating oil through the spark plug holes to break the pistons free. Any advice would be helpful.

I have a Allis Chalmers Model "M" gas powered dozer. It has sat for a few years prior to me buying it. I was moving it and it started to sputter and died. I found rust in the sediment bowl. It was flooding gas out of the intake so I pulled the carb and cleaned it out, and added a fuel filter. I can't get it to start. Can anyone provide the intial settings I should have the idle and mainjet adjustment needles set at? It will fire on 1 cylinder and die. It has had a recent set of points installed in the mag. Next step is some new plugs. Anyone have any ideas what I should check? It ran great prior to this? This is a hand crank model, and I have gotten plenty of practice trying to get her to go!

   By Pete ( on Monday, August 15, 2005 - 4:14 pm:

The manual only says that turning the idle adjustment screw IN makes the mixture RICHER.
For mainjet adjustment it is the opposite, turning the screw IN makes the mixture LEANER.
I would try turning the Idle and Mainjet screws out 1 to 1 1/2 turns as a starting point. Also be sure the butterfly stop screw is adjusted so it will idle. Good luck, Pete

   By T Faul ( on Tuesday, August 16, 2005 - 2:53 pm:

I will try to see what happens with the settings as you recommend. I had them both set at about 3 turns out. It idled fine prior to this happening so I left the butterfly adjuster alone. I think there may be a problem with the mag, or the plugs, so I am going to also put new plugs in as well, and check for a strong spark. I had pulled the plugs and tried some either with no results. Will keep you posted

I have a HD-7G serial 24475 with a clutch that won't release. It is a wet clutch. When I tore into the machine, I found that some bolts were missing that bolt the clutch assembly into the drum and others are loose. Several bolts had loosened so much that they were sheared off from the turning of the drum. Would this cause the clutch to not release. It seems to me that the clutch would just slip constantly. Any thoughts before I go any further. I'm hoping I can replace the bolts and loc tite them without removing the track and sprocket.

Are they the fiber discs or the bimettalic and require 15 w/ two being tapered according to service manual(specified thickness .152-.157 and mine are at.125). The steel disc measure out Ok from what i could measure. i have to get a proper caliper to check for sure. i bought the dozer last year and has worked wonderfully except right now.

Hello all,
I have a HD-5 dozer, that I am repairing the clutch on. I sent the pressure plate and clutch disc off to get redone. When the came back I tried to reinstall both items, I found that they would not fit. I beleve that they made the pressure plate and clutch disc to thick. I was wondering how thick the pressure plate is suppose to be and the clutch disc. Thanks for any help.

Hi All. Trying to learn as much as I can. I have an HD7W, according to the serial. Like the other fella's post, my left side does not work. I took the clutch cover off and watched the clutch housing. With the right lever back, the crawler stops, the left drum continues to turn but does not drive the crawler. Pulling the left clutch back, it still turns. Do I have a bad itermediate gear and clutch? Do I have to tear the left side apart to fix? Thanks!

Have two HD11,s and HD6, also had HD15. Good tractors. Too bad they didn't use cummins engines years ago, there probably wouldn't be any yellow tractors today.

   By on Wednesday, December 13, 2006 - 12:30 pm:

Mike, I've had my hd 5 loader/crawler for a few years, and I'm just now having issues. Water pump went out. I don't use the pi$$ out of the old girl, just run a round the farm clearing things. My grandfather was a dozer operator for 30+ years and said the old a/c dozers were hard to beat. I only use mine about half throutle and other than the waterpump, which is not all that bad to repair, I've had no issues. I know the clutches and rollers can be a bear, but if you have someone with the right tools and know-how to help, or talk with, it can be done. Just don't look at your If you can, find one that has gone under a renevation of some sort and get a few years out of her before you have to put too much $$ in her. I wouldn't give up my HD5 for much of anything. Really enjoy using it.

   By drott on Wednesday, December 13, 2006 - 7:48 pm:

Not hard to fix. You can still find a lot of the parts for the motor. That was the most popular machine by Allis that they every made.

Lot of the parts can be made in machine shops. Common tools for many things but the Engine where there are some special gagues to set the injector rack timing.

Manuals are out there. Simple to take apart. Except for the motor,you only need about 5 wrench sizes. That does not include the outboad bearing on the truck frame. Basic pullers can get the bearings out.

Commong 80/90 for most oils. About 2 gallons for EO.

looking for a 471 detroit engine in good running condition for a hd9b dozer

   By drott on Wednesday, December 20, 2006 - 5:05 pm:

Be Careful, on the HD9B you have to make sure that the engine rotation is correct, the blower and exhaust are on the correct side. The latter two move easily from one side to the other.

If I remember right the 471 can come in 11 different configurations.

Other factors to consider is the Fan and tensioner for that model.

Engine Mounts.

The last but not least is you need to have the correct oil pan and pump. Requires deep well.

If you have an old motor, the cam parts and other things can come off and you can convert it for the Allis.

If your motor is in one piece then getting pistons, sleves and some of the other wear parts might be easir and just as cheap if you have to hire someone to convert from one model of 471 to another.

It will not matter if you have the orginal 2valve head or the later N series either one will mount in to the HD9. You can use the exhaust manofold of the Detroit if you want to cut the hood a bit.

   By Greg Rau on Thursday, December 21, 2006 - 9:35 pm:

Thanks, for the information, exhaust is on the left side sitting on machine and blower on right. this motor is getting water in oil and oil in water . we took the head off and all we could see is two of the small rubber gaskets where worn and looked like they was leaking water and oil thru each other could not find crack in head or block. put new head gasket and seals on and is doing the same thing. got any idea's . thanks

   By capi75rs on Sunday, December 24, 2006 - 7:42 am:

On my HD5g I had oil getting into my my radiator but no water in oil pan. Thanks to Hector I found that the water pump was bad. The water pump also serves as the oil cooler and it has an internal crack allowing high pressure oil into lower pressure antifreeze. I paid $3000.00 for my dozer which had two new clutches and a recent engine overhaul. The paint is bad and the undercarrage is about 30-40%. I have a hydrolic leak at the lever housing, but not bad. Overall I really enjoy the dozer, when I bought it I knew I would have to spend @1200-1800 to get her back in tip-top shape, and have slowly been getting her up to date. Until the waterpump went out I was using the dozer on a weekly basis.

   By mike on Sunday, December 24, 2006 - 11:01 pm:

capri75...that sounds very reasonable. 4,800 is probably the taxes youd have to pay for a new if i only use it once in a while on my brothers 5 acres (renting a small dozer around here is like 1500 a week...)or maybe do a little side work it will pay for itself real quick. thanx again and have a merry christmas!! mike

   By drott on Tuesday, December 26, 2006 - 8:03 pm:

On that Oil/ Water leak check your oil cooler. On the right hand side of the motor. They can lean through there.

When you open up the side cover to the air box do you find any water/radiator fluid in there.

They can leak water via the injector there is a copper gasket in there that is crimped in place because it is water cooled. A detroit is a bit different since they are a 2 stroke and the entire injection system is in the head vs a pump on the outside.

Have the head pressure tested. The block could be cracked. I had one that way. Not until pressure was applied could we find the leak.

Detroit 471 normally have more ways to leak than any other motor. Normally it is the oil.

YOu can easily find a 471 manual that will give you a good picture of the water flow and oil flow.

They are very picky about deck to piston sleeve clearance. Did you have the head checked for warpage.

Jump on EBay and bid on this manual. There is someone selling an HD5 parts list manual as we speak for about 5$. What ever you end up paying for it, it will save you that much in the first purchase you make. It will allow you to talk apples to apples with parts sellers that don't have access to the dealer part numbers. My first purchase saved me over 400$ on a $600 part because I could use the internet and hunt it down.

Good luck,

I have two service manuals for the HD 21. One is a brown cover with a metal clamp frame spine. It says Construction Machinery Division AC on the front. It's printed in June of 1959. It has many photographs, very good instructions on repair and overhaul processes. It has 440 pages plus about 34 pages of extra sections.

The other one is a Fiat-Allis HD-21P service manual set. It's in a blue vinyl metal back cover notebook containing 7 manuals approximately 3 inches thick printed from 1965 to 1976.

I'll take $100.00 for the pair or make me an offer. I would imagine the shipping would be about $10.00 in the U.S. Hope someone can use these. Doug

Hello, I need help. I just purchased an hd3 right side track won't brake. I took the cover off to the clutch and brake housing and it has a lot of oil. I don't think it's normal since the left side doesn't have any oil and works fine. I believe I have a bad seal somewhere in the shafts. anyone have info also if it's the seals where to purchase them. thanks

   By Jim Johnson on Monday, May 28, 2007 - 9:27 pm:

Hello, I have a 1951 HD5B with dozer blade.
Can anyone help in locating a breakdown of, or a replacement of, a control valve for it? The only identification on the valve is, A.W. Cash Co., Decatur, IL and the number 21716. The valve has three positions; forward-to the right powers the blade down, halfway back-to the left powers the blade up, and all the way back to the left locks to float the blade. It mounts with four bolts to the hydraulic fluid reservoir in a square pattern with 4 1/2" between the bolt holes. Any help would be appreciated. I can't have the ONLY one ever made, but it is certainly turning out to be that way. I can't find reference to this anywhere. My dozer has effectively become a large doorstop as I can't raise the blade to move it out of the barn. I checked the pump and its good. The pressure relief in the valve appears to be inoperative and is keeping the pressure from building enough to raise the blade. When I open the valve to the raise position, the fluid in the resovoir swirls fast. I think that the guy that I had do some work on it left a piece out, but can't prove it, I wasn't there when he broke it down to replace the shaft in it. Help . . . .

Does anybody know where I could find a good used final drive sprocket shaft with driving gear for a HD11 EP serial NO. 14192 ? I cant believe what happend to the old one, it broke completly in two pieces between the sprocket and sprocket retaining nut. That part of the shaft is not under any stress that I know of.Again , it broke on the outside of the sprocket wheel. I dont know what maybe happend to all of the gears inside the final drive housing untill its apart.
Anyway , I need a sprocket shaft, drive gear, and inter and outer seals. Can anyone help?

   By forsonja on Thursday, June 28, 2007 - 11:00 am:

I broke one in the same place 2 years ago. Stress is transferred from the blade to the frame just ahead of the shaft. My gears where fine, but you may consider changing the bearings at the same time. I got a shaft from for $900. Good luck. It takes a couple of days to change.

I'm looking at possibly buying a Fiat Allis HD11B. It's a real clean machine but the owner destroyed one of the front idler hub/shafts. Also, I'm seeing white smoke when accelerating against locked brakes (engine warm), the transmission pressure (powershift) jumps when engaging gears, but settles at just in the green, and there is oil on the grousers under the finals (leaking seals?). Can anyone suggest a fair price and/or solutions to the problems, or am I crazy and should forget it?

Hello everyone:

I am in Dallas Texas and looking to find out info on what I believe is a Fiatallis Model 20B.
On the ID plate it says:

20B CIT 008918
8215 / 22

I believe the 20B is the model number but what do the other numbers represent? I can't read anything else on the plate. What year would this possibly be, horsepower, and any idea on value?

   By Ray on Thursday, August 23, 2007 - 4:49 pm:

This is for Juan Elizalde on the question on his HD3 steering brake. It should be dry not oily, if its oily you will have to remove the steering clutch on that side also the brake band and replace the seal that is leaking also the steering clutch fibers and the brake band to make it work right. I can get you what ever you need in parts. Let me know if I can help. Thanks, Ray

my tracks on my hd6g are a little loose. I tried to pump them up with grease but I am at the end of my adjustment. I had one man tell me to take a link out is this ideal? I had another man tell me to shim it in to get more travel on my tensioner. I dont want to create more problems than I allready have. Does any one have a fix other than replacing the tracks? How muck slack can I have without a risk of them running off. I have uneven land and I only run in first gear.

thanks Charles Cole

ok my fiat allis FL9 has a crack in the crankcase on the bottom. It has been welded up. but someone put JB weld over the it seeps some. I have chiseled off all the old JB weld Drained the oil and cleaned up the bottom with carb cleaner and starting fluid and a wire brush. let it set for a week, would clean it off every other day with the wire brush and carb cleaner.

So what do I do? Go back with JB WEld? it lasted 5 years last time....or???? what do I put on it........or do I put JB WELD on it and something else over it.••••••••••••••••••••

I'm having trouble with my HD-11S blade control. Sometimes the blade only moves so far down and stops, but will continue moving if I play with the control. Sometimes the control is in the middle detent, but the blade wants to peg in the up position with the pump whining. I havn't been able to determine the vintage of my machine because I get differing info on serial numbers. Mine's serial 1979, and depending on the book you use, it's either a 1956 or 1971 vintage. It looks like the 1956 HD-11B. Anyway, My blade control is some sort of rotary setup, and I havn't found any valves that look like this. I plan on taking it apart, but don't know what I'm getting into. Any info, ideas, or suggestions?

   By drott on Thursday, October 30, 2008 - 2:18 pm:

When pump whines it means you are in cavitation or short oil.

Check oil level first and check your sump lines that lead to the pump to make sure that they are not going bad and you still have good oil flow.

Check filters first. Tank and line filter. Does you blade control say awcash on it.
The seiral number is stamped on the back left hand side on the final drive housing by the support bracket for the left fender well and holds up your hudraulic tank.

It means you are in pressure relief and it is not holding.

The valve is simple rotary valve. If you tank has an opening in the side then there will be a screen in it and it may be plugged.

HD4 Track
Looked at a HD4 Dozer yesterday. Track was near 100% wear on pins/bushing but less than 50% on rails.

Lil dozer fire right up, ran right, had good tin, good power, ROPPS, did numerous pivot steers and turns and track still has life left for light use. And I must say, a handy handling machine.
Sprocets available?
My question is availability of new track rails and sprockets. Who has replaced track on HD4 recently?

   By drott on Wednesday, July 01, 2009 - 9:48 am:

Yes You will have to pull the steering clutch from the Machine. Not a hard job but need the tools and have to pull fuel tank. So means blade has to be up so you can roll it a wee bit to get the bolts out. Use the steering clutch brake as your sling and support it. Mark the Clutch and the plates on both sides because the holes are not uniform Othrwise it will get fustrating. They are alingment marks

Just purchased good HD7G but need undercarriage parts primarily rails and sprockets or information on what would interchange. Any help would be appreciated.

   By Ken ward on Wednesday, September 29, 2010 - 1:07 pm:

HD-5 dozer starts to miss and flutter after about 30 to 60 minutes of use. It appeared to be getting hot so I thought the thermostat may have been stck so opened it up and found no thermostat at all. I installed a thermostat, changed the oil, filter and replaced the 1st stage fuel filter and the dozer continued to do the same. She runs good for the first 30 to 60 minutes and then starts to flutter and lose power some but continues to do so if you keep running it. Once this starts it can be shut off and allowed to set awhile and then start it right up and go again until it starts fluttering. If you continue to work it will get to the point of not being able to even crawl it back to the barn. I thought it maybe heating up and I have removed the radiator, cleaned it good inside and out with air and water, checked the core which appears to be in good operational condition, removed the water pump to assure the impeller is intact and working which it is and now I'm at a loss of where to go from here as I've taken all this off and so far all is in good shape. I've been working on it as a heating up, coolant or circulation problem but I'm not sure the problem is in the cooling system. I'm no mechanic let alone diesel but I can manage to tear stuff off. I just hate to do so and not find the problem because whatever I tear off I must put back on and I'll probably end up having to make gaskets for all of it that takes one. I've got a gentleman leading me through the cooling system checking of parts but I'm open to others opinions. Oh yeah this 271 runs great until it gets to the 30 to 60 minute time interval and then she starts her missing/fluttering and progressively gets worse. It doesn't appear to lose any water or boil over neither does it bubble in the radiator when first started up cold to indicate a head gasket problem. It doesn't blow heavy dark smoke but does blow it when she starts the miss/ fluttering. The last time I couldn't even get enough power out of it to make a sharp turn using the brake to get it into the barn after running it awhile after the fluttering started.

   By Bill on Sunday, October 03, 2010 - 2:39 pm:

Your second to the last sentence gives the best lead to your problem. I believe that you have either a bad injector or a fuel flow problem. This is what I would do lacking any proper test equipment. With the engine cold, have a clean container and remove the fuel return line. Set the throttle above an idle and mark it so you can return to this position later. Measure the time that it takes to fill the container and write it down. Now take the machine out and run it until you start having problems. Again do the above test, if there is more than a little difference in quantity between the first and second test you have a fuel pump that is getting bad or a restriction in the suction side of the fuel system. Like filters, restriction at the tank or a bad fitting. If the tests were near equal then you have a bad injector that is probably hanging or has excessive wear.

I have an AC HD7 with a 371 Detroit engine, 4spd transmission and dry steering clutches. It's disassembled for restoration. I need to talk to somebody about "weak final drive" issues. I am considering the idea of adding weight to the dozer push arms and installing a turbo charger upstream from the super-charger... more stump pulling power! Thanks... Walt Rust

   By roger on Tuesday, April 05, 2011 - 9:41 am:

I have a HD7 that was left to me and was wondering if there is any interest in this thing.
It is cable operated and has a blade on it. The tracks look good and was told by father in law,who owned it, that they have never been repinned and doesnt need to either.It ran good when parked 20 years ago, now seems to be froze up.
Has been in a barn whole time. With scrape prices high I'm going to get rid of it, but thought someone might want it for restore or parts, but not for less than scrap.
