There are three bearings on the main shaft when they get REAL BAD they will take out the oil pump then of course the rest of the trans will be full of metal from the destruction . Time to fix it is NOW before it gets to the destruction stage because it will double the cost when it blows . I have done a few 5000's both before and after so I have seen the mess first hand.

It also might explain the low preasure in it now as it got alot of use after and had the clutch packs replaced too. I still have that tractor and dream of fixing it up again someday when the funds allow. That tractor could sure pull a 4-14 plow, only problem was traction even with fluid and 3 weights on each side. It sure would put a buddy of mine and his 656 farmall to shame at a plow day. ;^) Greg NE [Reply]  [No Email]

I also run an extra gallon or so of oil in them so the splash is heavier and lubes them better . I run extra oil in all of my SOS's too the 801/4000's will cavitate on a steep side hill when I was pulling logs with them finally stopped it with an extra gallon in them .

I haven't looked at this tractor in a long time but only remember the pain in the butt level plug on the side like my 63 4000 and 59 971. I just wish I knew 1/8th as much about these trannys as you do as I really like them. Picked up my 971 this summer from an older farmer that parked it when it quit moving, sure enough it was the imput shaft splines and thanks to the folks like you on this board I knew about the trick to stand the rearend on end to keep washer from falling out. Was out tooling around with it about three hours later the same day and it works great. I did make me up an adapter to run tranny with a drill first to check the oil preasures at the three ports to see if it was worth taking a chance on. Didn't need another tractor but you know how that goes, price was right and wanted to save another sos. thanks Greg NE [Reply]  [No Email]

The description of the problem initially does suggest input tho. Rod [Reply]  [No Email]
