Hi I have a D7 7M. The outa bearing on the RH final has let go. You can put a crow bar behind the sprocket and move it heaps!!! So what I would like to do is hopefully drop the track and remove the final housing complete from tractor and bolt a good used one back in. Can that be done? And does anyone in Aust have one they would like to sell? Cheers.

If you tell people where you are in Oz it makes life a lot easier to find parts and help.

Oh yeah ok. I'm in Central west NSW. Not to worried on location in OZ mate. Have a truck and float and all major highways run thru my area. So should be able to get on freight easy enough? Cheers.

the amount of work required to replace the whole final drive would be equivalent or more work than just replacing the outer bearing. my d6 9u had the outer bearings failed on both sides of the final drive. i completely dissassembled and rebearinged and resealed both final drives. but i could have gotten away with just replaceing the outer final drive bearings and the outer bellows seals if i wanted to do it cheaply. you can replace the outer final drive bearing without removing the track frame and with out pulling the sprocket off the sprocket shaft.

I have a lot of that stuff. No complete finals though.
What specifically do you need.

Thanks for the replys guys. rmyram that was some good info thanks for that. Andrew I'll have a go at the suggestion of removing bearing etc. I'll grab a service manual first tho. Then I'll drop you a line. I suspect I'll need bellow seals, bearing complete and anything else easy to damage when this kind of breakdown happens on that side of final. But I'll chasing parts for sure. Won't happen for a month or so yet. I'm starting the rebuild on the old E shortly I'll do that first. Thanks

the bellows seal may still be intact and may only require new cork gaskets, it is amazing how forgiving that seal design is.

The bellows seals are crazy expensive, and be sure your axle shaft that is pressed into the tranny housing (dead axle) is not damaged. If it is, you need to replace that, too and that is a big job.
