Good news! the negatives for the pictures showed up and it looks like they are 666 units. Its hard to tell peering at the negatives, but it looks like these units are in A-1 shape, about 8 of them! Does any one know if putting them on a disc will make posting them easier? I don't have a scanner.

   By bill ( on Sunday, December 24, 2000 - 10:36 am:

If you have 35mm negatives. I have a scanner here that can scan them in and get them posted on the show n tell side and then make a link to it for everyone to see.

One thing is that with a true photo, We can make the picture bigger to get better idea of detail. I can still scan them and would be glad to help.

Have a good Christmas.

I was told that the tracks for a cat 312b were the same size as that on a d4, can i get a set of salt d4 rails for it? if so is it a high track or conventional d4?

   By Half Track ( on Tuesday, May 01, 2001 - 7:38 am:

To PE: If the 312B does use the D-4 rail, it will be the conventional D-4 & not the high track style. I will check to see what rail is on the 312B. Keep in mind if your usage is in high inpack
using the SALT rail is not a good idea. Will get back on this. HT

   By Half Track ( on Tuesday, May 01, 2001 - 9:26 am:

PE: The 312B has a 6.75" pitch which is the same as the std. D-4. But at this time I can't tell by CAT's part # if's the same rail. Odds are it is, but I'm just saying this with "NO" proof.
Now I maded a phone call to see or hear about the lubed rails for excavators that CAT has "JUST" come out with. They use grease & not oil. Here is what I was told the part#'s are.
For A 43 link> 1802689
For a 46 link> 1845859
Keep in mind that this info has just hit the CAT CTS guy's in the last few days. I will be getting my copy here in the next few hours or so.
Now be sure to check your s/n with your dealer to make sure what the rite part # is. Good luck & let me know if I can be of more help. HT

I've got a Cat D2 that dates back to around 1949. It's in excellent condition and only has around 1700 actual hours. The problem is that it's spent most of the last 30 years parked in a barn. It's got a dry clutch which I replaced back in 1980 because the pressure plates were rusted and pitted. Now the steering clutches are stuck and there doesn't seem to be any spring action in the levers. Any ideas on how to free them would be appreciated. Thanks

Need help with buying 9U dozer for parts

I have a D6-B that the running gear is about35% I am told and I have a chance to buy a D6-9U for parts. The motor was taken apart and the head was done but it is not put back together so I cant here it running. I am more interested in the chains and pads (mine are just about done and are a little thin to re-pin) as well as the usual other parts like injector pump, clutches, hubs, rollers, etc.
Could someone tell me how to check the tracks to see if they are worth getting into or not. There are one set on the tractor and another pair off. How high should the rails be? How many links should there be? Or some tell tail signs to stay away from. My D6-B has D5 running gear under it.
Also how can I quickly look at the running gear to tell how bad it is (I'm kind of new to this but am learning fast$)
The guy wants 2k (Canadian$) for the tractor and extra tracks. Thanks in advance for the help.

I have put 13 Caterpillar Service Magazine on Ebay. They are all from 1952. I also
have 1951, 1950, 1949, and 1948. It was a pain in the butt entering them on Ebay
individually but someone suggested doing it. Just search for 'caterpillar service
magazine' and they will appear.

I am accepting offers on the remaining as a lot. I would like at least $50 plus
shipping. They have indexes and a notebook. Email for info.

My brothers and I have an old D7 that we inherited and are interested in selling. It is in very good shape, as far as the under carriage,75-80%, and engine(s) go, but looks beat up. The serial number is TS 1094. Does anyone have any idea how old this fellow is? It also needs a throw-out/throw-in collar for the starting motor. Cat wants a body part so I wonder if anyone knows where to find one that might not be so costly.

Can anyone tell me about direct electric start on the old D2's or D4's. Does this mean there is no pony motor. Been looking for a dozer and would like an older cat, but don't want the hassle of the pony motor. Any help appreciated. Also would like to know what it takes to convert a pony start to direct electric if this is possible.
Thanks, Farmer.

   By dieseldave ( on Tuesday, September 17, 2002 - 8:08 am:

I've seen D311 and D315 power units in cranes that had both pony and 12v direct electric start. Apparently one used the pony for starting when cold (or if the batteries were low) and the direct starter when the engine was hot.

Hi Guy's,

This is the response I've had back about the acmoc site being down - look's like you'll all have to be patient!!!!

"I checked it first thing this morning and everything was just fine, but I came back in and checked it again about 10:30 and it is offline, I am not sure what the problem is, I can not get in touch with the tech guy where the server is located, this being Easter Sunday and all, but I have no access to the server at all.

There have been some big storms moving thru the area so it is possible that the power might be out up there or some other problem along the line.

All the sites that I host are down right now, and until I can contact Joe I have no way of doing anything about it.

It is possible the site will be down until tomorrow, all depending on how long it takes to get in touch with him.

Sorry for the inconvenience but this is where we are at right now.

Hello people
I need info on how to adjust the steering on a 1951 D2. The foot brake works with a small effort but does not return without pulling up on the peddle. This is my (our) first working with a cat. We have worked with several IH wheeled tractors. We own 3 IH tractors and 4 Gibsons and have had 2 case tractors.

   By TomA ( on Thursday, July 03, 2003 - 10:36 pm:

It sounds like the brake pedal has siezed on the shaft. there is a grease fitting that is accessable through a hole in the fender. Also check to see if the return spring is working properly. You may have to take the foot pan out to check this out.

The fellow says it works good for about 150 yards and then it is like the clutch goes out and quits pulling like the clutch was pushed in. He says it has a wet clutch and I think they put regular hydraulic fluid in it. 1) how do I know it is a wet clutch? 2)Can you change the clutch without pulling engines etc... I am only paying $2000 for it and will do the work myself. ADVICE??

Current SAE 30 TO2 is NOT the same as engine oil and unsuitable for use in engines, it is true that the old straight 30W was used in both but the modern 15W/40 for engines and TO2 for transmissions perform much better and are partly responsible for improved component life over the last 20 years.

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!

Need help with a Cat. 951C problem. I recently bought a 951 for some light land clearing work. After using it for around 50 hours I suddenly lost all breaking and drive on the right side.There is also fluid leaking out around the sprocket on the right side as well that wasn't there before. The left side seems to be working fine. The break clutch fluid was low (approx. 4 gallons), but filling it didn't help. I don't know much around the internal mechanics of the drive and breaking systems. Can someone help me out with some general information about these systems and maybe even some specific information about what have happened. I have my ideas....

D4D LGP Swamp Dozer Track Headaches.

I own a Cat D4D LGP crawler dozer whose 3304 engine runs like a Swiss watch, but I'm being slowly nickel-and-dimed to death with undercarriage problems. The D4 dozer is used in very muddy terrain to excavate catfish ponds, and the job has come to a grinding halt for now as I finally just ran out of ideas as to how to stop the track from peeling off the sprocket. The sprocket teeth wear down at a ridiculously fast rate, and I've gone through three sets of sprockets in as many months of use. Additionally, the track adjuster cylinders periodically spring grease leaks and have also been replaced twice, along with their pistons and seals. The main problem, though, is that there seems to be some sort of fatal mis-allignment that starts off with the track skipping off the rollers and then jumping off the sprocket or front-idler if the operator does not stop and reverse direction right away. I tried changing the front idler spacer shims but that had no effect on the problem. I'm reluctant to sell this D4 Cat since the drive train runs so well, but I'll be forced to do so if the undercarriage gremlins are not exorcised once and for all. Any ideas ?

   By muttley ( on Monday, August 01, 2005 - 2:24 am:

Rick, I would hazard a guess that your D4H is going to need a rebuild pretty soon. Worn piston rings will cause engine oil to vent out of the exahust, though you might get by with a replacement of the piston rings, and without having to go the whole hog and replace crank bearings and all the associated seals tec.

I have a Cat 955H track loader that has a steering problem. This happened once before but started working again. I don't seem to be getting any pressure from the steering clutch pump. If I take the hose cap off going into the filter I get no oil. I also took the hose off going to the pump from the strainer and filled it with oil(a pipe from the bottom of this housing goes directly to the oil pan). The oil did not get sucked into the pump so am wondering if this proves the pump is bad? The machine's S/N is 60A10479. Are there other places to get this pump or a center housing for it? Cat is telling me it is discontinued.

Microprocessor controls

Wrestling with my insomnia and thinking.

What happens with all this new equipment that has microprocessor controls when they fry? Will the manufacturers continue to support the growing number of systems. Will an aftermarket develop for obscure equipment microprocessors?

What about electronic engine a diesel engine useless now without them functioning? I understand some new dozers won't even move if a sensor goes out.

Equipment is not like doesn't get replaced every 5 or 10 years...not normally. Is this the new intention, to make it so that it has to be replaced when the microprocessors go out?

Can the systems be over ridden and run without the microprocessor controls? I don't particularly need a microprocessor to sense the digging load and provide a 6 percent rise in engine rpm until the load is reduced (thought this was what a govenor did anyway)...all in the name of a 1 second reduction in cycle time... I seriously doubt it. I don't think we make people to operate that consistent to take advantage of the benefit.

The programming in some of these systems is so unique that only the original programmer can reproduce it. In the drilling business we have multimillion dollar BOP control systems that have been replaced because the multiplex programming team dispersed to the winds.

Your thoughs?

Hey Guys,
I am new to Cat Dozers and looking at purchasing a D4E #28X01662 for odd jobs around the farm. It was used for a drilling unit a neighbor is selling. It had a large drilling platform and deck off the back powered by the PTO & Hyds. This has since been removed and I must re-fit the fuel tank and ROPS, hyd hoses and a few other things. The undercarriage is about 65% and pins have not been turned yet. Muddy wrk. 8' foot tilt blade is tight! No slop in it what so ever! Seller claims about 2500 hrs on it. What do you think its value range would be and do the D4E's have any notorious problems with the trans, motor or anything I should be aware of? Would a drilling unit promote wear in other areas to look out for?
Any advice would be much appreciated!

In 1952-53 The people of the Bella Coola Valley, located on the central coast of British Columbia. Decided at that time to construct a road from the coast of B.C. to Anahim Lake B.C. Using nothing more than a late forties era International TD 18 Dozer and a new 1952 D6 Catapiller these people constructed what amounts to a wonder of the world. 43 miles of wilderness road, constructed using only these two machines and a lot of dynamite, as well as blood sweat and tears, a road that gains almost a mile of elevation through the rugged coast mountains of B.C. For anyones interest this is a must see road, still used but little changed in many sections since construction I am writing a tribute to these amazing people and would like to get good photos of these two machines, for use in that tribute.

One dealer wants to sell me a 39 link assembly w/ a 6.91 pitch (sprocket to match) and another one is trying to sell me a 40 link assembly w/ a 6.75 pitch (sprocket to match). I have searched the web and made many calls but I cannot determine the year of the machine or the correct (original) undercarriage. I have been told (and I don't know if this is correct but it sounds reasonable) that as long as the sprocket matches the link assembly then it would not matter which way I went... is this a true statement? Is the later (I believe D5) 39 link undercarriage better than the older (I believe D6) 40 link undercarriage? Will this have any effect on the torque at the pad/ground of the machine (w/ a different pitch? - I know changing tires on an car changes the effective gear ratio)? Will my pads (currently have a 40 link assembly - Berco CR2000) bolt up to a 39 link assembly (fyi.. one salesman came and took measurements - claims that the sprocket appears to be for a 6.91 pitch even though it has the 40 link assembly on the machine - sprockets are worn past being pointed or sharp - more like bumps now)? Any preference over Berco versus Nexus (Cat Classic). Lots of questions I know. Any help at all will be greatly appreciated.

Hi Hector, thank you for your response.
It is a D4E with a clutch, not sure whether that answers your question about direct or not.
The mechanic told me that there are two broken ball bearings and two gear wheels broken inside the transmission and that is why I want to replace it.

I've got a D6c 10k dozer with a 3306 engine that's got a low oil pressure problem. I plumbed in a pressure gage and I get 6-7 lb. at idle and around 20 lb. at full speed. The manual says minimum is 7lb. at 6-800 rpm and 24 lb. above 1500 rpm. My check was with the engine only partially warmed up and the book spec. is at 210 F oil temperature so my actual pressure is probably even lower that I tested.

Replacing the oil pump and crank bearings doesn't sound like it would be too bad of a job if that's what it takes. Does anyone know of any other likely causes or checks I should do before pulling the pan?

The local Cat dealer suggested that I tear apart the oil filter to look for debris and to get the oil tested.

Sorry for the second posting, but I believe the machine is a Cat D4 7U with a Cat loader and bucket on it. Does anyone know the weight and horsepower of these things? Also, is it impossible to start them in the cold? I live in Minnesota, so cold is an issue.
I used to own a TD-9 with a Drott loader on it, and I got a lot of work out of the machine. Are these old cats comparable to my old 9. Assuming its in great shape, could I work if for logging and clearing a few times a week, or should I forget it. Any thoughts are appreciated. Thanks.

I was running my D7 17A Cat this past weekend building a tank and the engine started to knock when I was backing up to get another load of dirt. The exaust stack was clear before the engine knock started and was clear after the knock began. It sounds like the noise is coming our of the front of the engine around the timing gear housing. I took a wrench and cracked open each injector line one at a time while the engine was running and the knocking sound becomes much less when #4 injector line is opened. I chalk mark on the front drive pulley on the crank shaft and used the gasoline cranking motor to turn over the engine with the compresson release on. It appears that the noise occurs on every second revolution of the crank shaft. I took the side cover off of # 3 & 4 crankcase and checked the rods but could not see any problems with rod clearance. This was done using two pinch bars. I did not look at #1 & 2 rods. I removed all access covers on the timing gear housing but could not find any problems with any of the gears except for a tiny chunk that was knocked out of one tooth on the side of the timing gear. The timing gear had a slight wooble while the engine was running slowly. I am going to put in some new injectors this coming weekend but a mechanic told me that he did not think this would resolve the problem. I also removed the tappet covers at the top of both heads (two cylinders per head) and could not find any problems with the exhaust and intake tappet clearance adjusting bolts. Three years ago I had problems with a bearing and gear failure on the governor. The lower bearing on the fly ball governor came apart and the ball bearings could not be found when I replaced the parts. I did find a couple of the bearing balls when I changed the oil later. I think this may be what caused the chip on one of the timing gear teeth. I was told by a heavy equipment contractor that fuel injection problems could some time sound like a rod knock. Has anyone experienced a similar problem like this in the past?

But, now the right clutch is always engaged and will not dis-engage. I pulled the plug out of the right clutch pistion and it appears to be stuck. It was working fine after the bearing replacement and started acting up the next day. I am asuming that something is broke or stuck. Has anyone had this problem before.

I am considering buying an older 955 track loader. it is is very good condition, but has not run in the last 6 years. It has been stored inside, so not weathered.. it has a 2 cyl pup engine to start the diesel engine. the main engine apparently has a cracked oil pan that was bandaged with epoxy, but no leaks again.. can the pan be removed and repaired, or is the most reasonable repair to patch it again ?? (recommended product??).

finally, the owner believes that the clutch needs adjusting, is this a large and significant job??

   By VAfarmer on Saturday, April 17, 2010 - 9:00 pm:

A neighbor has a 9U D6, navy surplus, and remainder life on his farm. 2699 hours. Data plate says it weighs 25,900 lbs. Serial # 9U11919. Seems to have the same issues as most vintage Cats, the APU magneto is not providing fire. Everything is complete on pony and dozer. Dozer is solid otherwise. He just pulls it to start it.
So thats my question to those who have one or knows about them, are pony motor APU parts like the magneto available?

I want to buy a CAT Dozer, and really wanted a D8, but simply cannot look past this D6 until I know.

My needs are for a dozer to push a root rake to clear about 50-60 acres of clearcut (mostly brush) and some dirt moving as always. Stumps are 5-9 years but not rotten. Have some new stuff with roots 1-2" is diameter. I'm making pasture. Also I have a lot of 8-12" cedars that need pushed and piled, for this, I really wanted a D8, and I know I'd work the snot out of a D5 or D6 with the cedars. However, I can use the smaller CAT to surgically move and pull stuff, and for a lot less fuel.

Are Magneto parts available, or should I just the wait and look for a bigger CAT?

Hello, my name is Darryl, and I was reading some of the post that you replied to about a D3 dozer having steering problems. I have kinda the same problem. We were using the dozer this weekend and the left side brake hung. We didn't stop using it when it happened and I think it wore the brakes out on that side. I got the brake pedal unstuck and I've adjusted on the brake and it will not turn on that side, so that is why I think it burnt the shoes off. The dozer will still push anything up good, but no left side steering. Is there something in the hydraulics that caused it to stick like that or maybe it was a one time thing? I know that I'm going to have to replace the brake shoes on it. Could you tell me what all has to come apart to replace them? I've looked at it and didn't know if I could just replace them or does the clutch assembly have to come out. Any help will be greatly appreciated.

Early Cat 955H SN# 60A3334 with hand steering clutches. I am looking at getting this dozer but it currently will not run. I am planning on checking out the motor before trying to start it as the crawler cracked the oil cooler housing last time it was ran and has set for 2 years since then. I need to get it home first though as the owner wants it out of there and it will be going to scrap if I dont't get it. What do I need to do to winch this unit onto a trailer, whats required to freewheel these loaders as I have access to a trailer with a 15ton winch on it that will pull it up as long as it will roll freely. Any help or general info about these early 955H's is appreciated.

RD4 caterpillar dozer 4G2179 1948(pretty sure)Pinion flops around and won't engage...
Can't start the diesel until I get this fixed.
Do I have to pull pony motor to fix this?? What do I need to do to fix it??
Any help would be appreciated.
Or does anybody know where I can buy a starter to use instead of pony motor?

   By hector gemme on Sunday, April 01, 2012 - 1:54 pm:

You could check your lever action on the bar ass if he push correctly on the sleeve ass.with pinion and check your oil level in the cluch housing she maybe out off oil

   By hector gemme on Sunday, April 28, 2013 - 5:13 pm:

When these machine are running too slow they can blowing oil out from exhaust and check if the air breather is't plugged

I have a 55 cat D2 5U was wondering if any of you would be able to explain how to oil the wet it just a matter of putting lubricant in the pipe, which seems to lubricate the collar or is the lube fed from the transmission? I have ordered a parts and shop manual...but that should be in next week...and its sunny outside!

   By hector gemme on Tuesday, May 14, 2013 - 12:31 pm:

The transmission is completement separated from the master cluch and you should have a depstik for checking the oil level in master cluch

977H track parts interchange

I have a 977H 53a. It looks like I will need to replace the tracks and do some roller work.

If I am looking for a used set of tracks what is going to fit.

The only number I can read on the links is the master, as it must have been replaced.


I count 37 links.

my email is robertbible at gmail dot com. It looks like I will have to learn about track repair.
