Hey I have a question on my 9150 hope someone can help I know the tractor is mostly a white not sure which one, but anyways bought it at auction and well should of left it there. On the way home driving it and the power shift starting jerking between gears. Got out to look for oil leaks and none. I doubt this was the first time it happened. Well had only a couple more miles to go and got home. To find out it leaks the oil from the 3 speed to the transmission 3speed no longer functions . My Question is do they leak from the rear seal of the 3 speed or from a oil cooler someone said they heard this was a common problem. Currently I have the 3 speed sitting on the bench will need to disassembled but I can't see a seal on the rear of the 3 speed unless it is inside further. If someone can help me with this I may have a couple more questions this tractor was worked on before and some things don't look right. And have contacted 2 of my local Agco dealers and niether on is familar with them. Well thanks if someone can help.

Talk to a White/Oliver dealer.

It's been a while since I have worked on one, 5+ years, but I think the cooler for the three speed is its own cooler mounted to the back of the engine?

I may be thinking of the 9170/90 now that I think of it...

there is a seal at the back in overdrive housing that will leak oil into transmission/rearend. good time to re-seal the over/under while it's out.

Yes I did look at the cooler and they are seperate, so I guess it is the seal in the 3 speed. Is this common for the seal to go out or would something take it out? The reason I ask is supposivly this tractor had a new engine put in 1000 hours a go. And it doesn't look very proffesional what I noticed was under the bellhousing on the engine there are shims where it mounts to the tractor frame on one side has 3 shims and the other a flat washer is there a alinement issue here? And the pto shaft which goes from the pto housing up to the front would be the 2nd one you would pull out from the rear it has some rough spots on the end of the splines but engages fine yet

also I found the rear bearing race on the input shaft of the 6 speed so removed it and found the housing around that bearing has a hairline crack on the bottom part with the least material. Was this caused by putting it in park while moving? or somthing else? I think a new bearing will do good there and may get a lot of use from it yet. Is this a common problem or is there a good way to repair that crack without gutting the rearend? Well thats it for now any help would be appreciated. Or I need to find a White agco dealer that can tell me something.
