Restoration of 52N. After engine rebuilding and new clutch I am moving to the hydraulic issue.
Problem: Lift is jerky going up and it does not go all the way down to 8" from ground.
The cylinder is dripping oil, the pump has a light oil movement indicating that the pump appears to be working. The intake valve control has good free manual movement and the exhaust has a strong spring return. The hand lift control is not bent.
I do not want to remove the pump unless I really have to.
According to the IT manual, the improper lift lowering is probably caused by incorrect adjustment of the quadrant. I guess this will be my next step since I have the top cover removed. It looks like a tedious adjustment procedures. (I did not check, and I should have, if the intake valve control goes flush to pump housing)
The pump and bottom got a good cleaning with degreaser.
I have the new NAA hydraulic piston and the relief valve on order.
Suggestions…?
