WOW over 200 views since I last posted and no suggestions. I decided to pull the top cover off of the transmission last night. On initial inspection everything looked fine. I thought that maybe the oil supply line might be partially plugged so I removed the lines to blow them out. I removed the shor...

Here is an update. I pulled the engine, clutch housing and front cover yesterday. Everything seemed to be OK. The spring for the oil cooler bypass valve was in the right hole and the valve was not binding. That is where I thought the problem was going to be. I’m not sure where to look from here. Doe...

Everything didn’t go as I had hoped. When I got the loader back together the left steering clutch and brake was frozen. I put the loader in gear and let the clutch out and the brake came free. Great. :) That’s when I found the steering clutch was frozen also. I was able to move it to an area where I...

update oil in clutch housing

Here is an update on the transmission leak. I finally pulled the engine and checked the input shaft, seal and bearing. Everything was good. No slop in the bearings. I decided that I needed to spin the input shaft to build pressure in the pump because the leak would only show up when the engine was r...

If it is an earlier model with dry steering clutches the steering clutch fibers are probably rusted to the plates. If you can get it against something that won’t move and work with it you may get them broke loose. Just keep the levers pulled back and work the master clutch to put a load on them.

There should be two ½ inch bolt holes in the head to attach lifting eyes. The one on the rear of the engine is on the side and the one on the front is on top. I made some lifting plates from ¼ inch plate and cut slots in them to pass a chain through. I drilled a ½ inch hole in the other end to bolt ...

Before you start tearing everything apart, check for water in the steering clutch housing.
Find the plugs that are in the bottom of the housing and remove them. If water runs out then let it dry for a couple of days and try to run it again.

You should adjust both sides at the same time. As far as the braking, the harder you pull the more pressure you put on the drum. Just like brakes on a car or truck. If you pull the lever back hard and quick that track should stop and the dozer should turn. If you pull back with a little less pressur...

It’s great to hear that the leak is fixed. Was the seal damaged and did you need to install a sleeve on the shaft?

If the hoses or fittings are not leaking the oil could be coming from the front seal on the transmission. I have this problem on a straight 450. It will go through about a gallon an hour. The oil was draining out of a weep hole in the bottom of the clutch housing. I pulled the engine and replaced th...

I have been into several of those pumps but only one that was on a John Deere. Ford used the same pump design on the early model diesel pickup engines. The flex ring that Leonard is talking about is a flexible plastic looking ring that attaches to rivets on the pump and governor. The ring will deter...

The problem may just be a linkage adjustment.
Have you adjusted the clutch and reverser per the manual?
It sounds like one of the reverser clutch packs is getting pressure when it's not supposed to.

It sounds like a pin holding the linkage may have come loose in the housing.
The other thing may be that the brake lining could have "unglued" from the band and is wadding up against the drum.

Thanks for the pictures dmh. I had to remove the clutch housing on my 450 loader back in October. It was quite a job to get it out and even more difficult to get back in. It’s a lot heaver than it looks. I see in your pictures that the clutch return spring is broken. I had to replace mine also and t...
