Super A final fluid change

Went to play with the loader in the snow yesterday and was surprised to find that the tractor would not move. After idling for a few minutes, I could rock the tractor back and forth by hand, so apparently there's some water in the main transmission, but not a huge amount.

I can take care of the transmission easily enough, but those final drive pans scare the %$#@ out of me.

What are the odds that a bolt is going to twist off on me when I go to pull those pans? Would I be better served just trying to suck the old oil out through the fill hole? I've got a very expensive mityvac kit that I bought for bleeding brakes, and have never used.
 
Mine surprised me and came out fairly easy, some almost too easy. Think of them like the bolts on your crankcase oil pan. That whole seam has been soakin' in oil for years.

How much flex have you got on that vac system? There's not much room to snake through that fill hole and the past the edge of the bull gear to get to the bottom. Prolly be just as easy to drop the pans and have it done. O' course, that'll likely mean a couple of gaskets.
 
MKirsch: I've never encountered problems removing those sump pan bolts. When full oil is always above the top of pan. They come quite easy.
 

So they are exposed to the gear oil then? Good.

My biggest problem then will be dropping the loader bracket in the rear to access the fill plug.
 
By all means drop the pans then fill with new 90 or even 150wt then you can probably find leaks up at the top of the final drive good luck.
