7060 tranny/rear end oil level issues

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

I bought this tractor a couple of months ago. Hard starter but adding a gear reduction starter, had the injectors done, drained tank, new fuel line, new batterys and cables and she cranks right up now.
New water pump, hoses, filter, that's done.

Time to start changing fluids. Engine done, time for the tranny.

The tractor shifted well, no issues, just wanted fresh oil and filters everywhere. Drained the tranny that was at least 3 gallons overfull. Suction screen was fairly clean. Topped it off with ~7 gallons of oil and everything is good. The top rear end sightglass was full so while I was draining oil I took the sightglass off to get the level down. Again at least 3 gallons over full.

Had to go out of town for 4 days. Top sightglass now has oil in it and the tranny dipstick is down half an inch. Hmmm. The range tranny cover under the suction screen has a drip so I pulled it off to reseal. It wouldn't stop dripping so I got a good light and sure enough the shaft seal had a nice steady flow of oil coming from the rear end side of things. It finally stopped and no oil in the top sightglass now.

So I orderd a seal today. It looks pretty straight forward to pull the three pump assembly off. The manual says to remove the axial piston pump and then remove the other two pumps as a unit. Replace seal and reassemble. If anyone has done this and want's to offer any advice I'm all ears and would really appreciate it.

I have new AGCO filters for the rear end so I can stay busy changing that oil while waiting for the seal.

	I use a slide hammer with metal screw to pull seal. Make a long driver that will just slide over shaft to drive shaft straight and long enough to hit it from out side of housing. Not a good place to drive a seal in. Any time you have the pumps out replace that seal. MACK

	Thanks Mack. That was what I was thinking for removal/install.

	Got the rear end drained today. Put in two new AGCO filters. Everything very clean. Nothing unusual except for three orings in one filter housing? Took a good look at the pumps. I think if I make up a stud with no head on it it should be easy to remove and replace the three pumps as a unit. Working by myself again.Glad I removed the auxillary tank, lot's more room. The lines don't look too bad. Just need that seal to come in. I also noticed what I think the problem is with not wanting to go in park. Cable looks really bad. Looked at replacements and there in the $175 range! Louisiana is really flat so need to think about that one.

	Forgot to say no need to drain rear end. Very little oil will leak out while changing seals. I would remove piston pump, then the other two to gather. All three is a pretty good load under there + the gasket behind piston pump will leak some times, good time to replace it. MACK

	Finally got to work on the 7060 again today. Had to get the tobacco out of the barn that was cured then had to plant the field with soybeans for a cover crop. The pumps cannot come out as a unit. Have to pull one and then the other two can come out. Got the seal out and it was rock hard. Now the bad news. I ordered the wrong seal. The old seal has a number on it. What's everyone's experience with going to someone like Motion Industries for a seal? I don't want to wait four days for a seal but I sure don't want to do this job over either.

	Any seal that # should be ok. MACK

	Mack I took your advise on the piston pump gasket. Have that and the correct rear end housing seal for the shaft headed my way. I was reading my manual and it mentioned the 70265398 seal in the adapter housing can also cause oil transfer problems. I have this seal so I thought lets take a look. It looks pretty simple to change. Am I missing anything here? Also I don't have parts 21, 39 or 40 in my assembly? My tractor according to the serial number is like the 103rd one produced.

	Finally had time to get the seal in yesterday. Used three 7/16 long bolts to slide the first two pumps on. Worked real slick. So far as I can tell it is not transferring oil anymore between the tranny and rearend. Thanks for all the advice.
