4020 Powershift transmision leak

Northvale - PA · Jun 25, 2012

I have a transmission oil leak somewhere below the rear axles. I say somewhere because it seems to be right above the 3pt hitch lower link pivot assembly, but not visible, and 1 side only. I tried jacking up the tractor and tightening the axle bolts, but no change. Could it be the axle gasket? What else is right above the the link pivot assembly?

Sounds as if load control shaft seals are leaking. If it were mine I'd replace with bushings/seals from Bolings Machine shop. Place L/D control lever in "D". Trans/hyd oil needs to be drained before shaft is removed. Support draw bar support with a jack or come-a-long before removing shaft. On reassembly install shims to remove as much side to side motion of draw bar support.

thanks, I did not know that the draft control was the bottom pivot. Makes sense, but on all my other tractors, draft control is at the top link.

I would use the seals from Boling machine shop too.
