Have a D4E 27X standard shift that has a steering problem. This is the tractor that I move the rest of the non-running stuff around with. The right clutch was not releasing properly and steering was being done by the brake. Anyway decided that the problem was in the hydraulics of the Cultch Control Valve 8V and rebuilt it. Did not find any visible problem, but replaced all the seals and added. There were no shims in the unit before rebuild This fixed the problem of the left cultch handle not returning, but seems to have solved only a small part of the right steering clutch release problem - At idle speed, the tractor now will steer fine to the left, but does not drift to the right unless the break is used.

Do not think it is the pump since left works fine, but that is an easy rebuild it it could be the problem. Any suggestions??????? Posts 15, When the handle is released and the oil pressure to the yoke cylinder is stopped, the steering clutch springs pull the yoke assembly back to the engaged position.

Things to check: 1. Adjustment and movement of the steering control linkage. Too much leakage in the steering clutch control valve. Steering clutch discs or plate wear.

Weak clutch springs. Seals or steering clutch piston wear. He's the expert on the later stuff. Took some digging to find the oil pump specs. It is a two section pump, one section is the scavenge pump for the clutch and the other section is the pressure pump which should put out psi 2, rpm pump rpm and 8. Might be a good idea to check pump pressure. The minimum pressure needed to operate the steering clutches is psi.

Couldn't find the relief valve pressure setting other than a 1. Thanks Old Magnet We are going to check the pump pressure, but first we were going to replace filter and clean the screen.

May even replace fluid, although looks fine. We are also going to reset both linkage right and Left to see if that solves the problem. While rebuilding the control valve, we removed the cover to the yoke cylinders and checked the linkage length for each and they seemed to be fine.Discussion in ' Dozers ' started by FirstEliminatorApr 16, Log in or Sign up.

Cat D4 Transmission problems

He was moving some bolders around his yard with it and the dozer was doing just fine. His son got on the thing and the next thing my friend knew is that the dozer wasn't moving very well. It would roll along on flat ground, but as soon as he tried to push anything it would feel like the clutch is slipping.

He pulled the plate off and his brother had tried to adjust a linkage inside to put more pressure on the clutch. However, we realized this really only changes the position of the outside lever and doesn't do anything to push the clutch further on.Log in or Sign up. Heavy Equipment Forums.

I was pushing a small amount of dirt and it just stopped, not loud noises or anything. You can feel the gears shift but no movement or binding on the motor. Just looking to know where to start, anyone have any common problems or suggestions? ZEPPOct 29, Seems you'd have to break a bevel gear pinion shaft or lose the pinion shaft splines to kill power to both finals.

Problem with steering clutch booster control might be a suspect but again not likely both sides would go at once. Does the same thing happen if forward and reverse? Could also be a problem with transmission control. Speed clutches engage before direction clutch If I remember correctly.

Thank you so much. In September I bought a used Cat skid steer.

Caterpillar D2 D4 detailed starting sequence

I live in Texas and welcomed a closed cab with A. Have a very old Skat trak open cab. I had just bought ac. That had plenty of cedar and began clearing, after 2 months I had piled up a good amount, and decided to do some burning. While pushing ends and left overs in the machine abruptly quit, fortunately the bucket was down and was able to get out, only to watch the machine burn completely up in a matter of minutes.

Contacted State Farm and got amazing news it was covered and they did an amazing job of helping me through the process of replacing the machine which I did by December 1. I replaced with another Caterpillar c, amazing machine, I also immediately purchased a first alert fire extinguisher, JUST in case.

After a year and a half of just pushing cedar, the weather was right to do some burning and don't you know the machine quit, smoke coming out engine compartment same as last time, only difference was bucket was tipped up and door wouldn't open.

I was able to operate the emergency latches and grab fire extinguisher, made my way around machine and found the fire extinguisher would do absolutely nothing. So I had to watch another caterpillar burn to the ground.

Why is this happening -- I have learned that caterpillar sucks air in from the bottom of the machine to cool engine. Skat trak pulls from the top and Bob Cat from the sides.The Caterpillar D4 track-type tractor is a small bulldozer manufactured by Caterpillar Inc. Caterpillar first introduced the RD4 in [1] as the diesel follow on to the successful CAT 30 gas model. The RD4 originally weighed in at 10, pounds, and used Caterpillar's D engine, an inline four-cylinders, with a 4.

The D4 U series was fitted with the more powerful D engine. The later D4 series engines quickly increased in power, so the number "4" just became a figure of merit rather than indicating actual engine power. The Caterpillar D4 was used as the base tractor for the Trackson built loader that was known as the T4 or Traxcavator shovel. From Wikipedia, the free encyclopedia. Small bulldozer. Caterpillar Inc.

Help, At first I figured I has bad fuel or a fuel filter that was full of water junk. But I replaced filter little water theredrained lines Looked like clean fuelDrained some fuel out of tank, it looked OK too So I primed the lines and it would not start Knowing the book says not to put fuel in new filter, I checked filter, after 10 min of cranking it only had 1 inch fuel in it SO I filled filter with good fuel anyway Well it started like a champ But after 10 min of running it acted like out of fuel again does not quit, just run at idle speed, some smoke too.

Let it sit 20 min it will run a short time then do it again. I'm going to check the lines between the engine and tank for a leak BUT,My question are: What is in the tank? Tank is full and hate to drain it. How do you test pressure out of the transfer pump? There is no primer pump on the filter housing? I know the manual says not to fill the filter because the chance of crud getting into a new filter but if it's filled into the outside holes on the filter it should be okay.

As far as checking fuel pressure- on the filter housing there may be a fitting, some engine don't have them but may have a plug to remove so said fitting could be instaled. Generally fuel presure runs in the area of psi. Hope Hector or Catmech or anyone verifies that. Did you check to make sure there is only one O ring seal on the fuel filter- sometimes when changing a filter the old O ring will stick to the filter base and cause air in the system.

Did you look to see if there are 2 fuel filters? You'd like to think they're close together if more than one but that's not often the case. It does not sound like a lack of fuel from the tank or an air leak. If it is getting air it should just die and if its blocked lines it shouldnt run at revs for 10mins and then after a rest.Discussion in ' Dozers ' started by flametamerAug 21, Log in or Sign up.

When it is in neutral, it is still in forward or reverse depending on if the shifter is leaning toward the forward or reverse side. It never gets to neutral. The fluid level is good, and it looks clean. It has been sitting for a while. I think it is a hydraulic or internal transmission problem but that is as far as I can go. Any help will be appreciated.
