37A Powerlift/Rockshaft Rebuild.

Grandpas37A · Oct 12, 2014

Got a 37 A that I'm working on. Changed the fluids. The powerlift still doesn't work however. Does anyone have a link on how to rebuild them? Thinking the piston is stuck. Also a link for parts would be great. Thanks

For the rockshaft cylinder you will need; 1-A3957r washer, 1-A3956r seal. 1-A623r gasket,1- A1447r gasket and 1-A412r gasket. Once you take the rear rockshaft off, you will see the cylinder bolted on the housing, remove the 4 bolts holding the cylinder in place and remove it. that will leave you the piston fhooked to the connecting rod. the A3957r washer and A3956r seal will go on the piston. Just reverse assembly. You will need a good friend or a engine hoist to remove and replace the rear housing.You may not need the A1447r gasket. That goes between the powerlift box and the rear housing. A good 30w oil in the Powerlift box some use hydraulic oil and you should be good to go.

Do you have the pto engaged?

Is the clutch engaged?

Forgot to ad, the rockshaft won't go down unless there is a heavy object on it. You may try a large pipe wrench or adjustable wrench and rotate the arms down. When started and the lever or foot controls are used, it should rotate in the up position.
