leaking ram piston?

You will have to pull the lift cover off and then remove the four bolts holding the ram cylinder to the hydraulic housing casting. Clean both mating surfaces and replace all three gaskets. One has three holes in it and is what actually contains the pressurized oil. The other two are just ther to make the ram cylinder be level so the three hole one doesn't blow out from being unlevel.

Be sure and hone the cylinder while it is out and replace the steel rings or obtain a new NAA piston that carries the rubber O ring with backup washer.

Good time to replace your pressure relief valve too while it is easy to get to with the cover off. However you can replace it with the cover on by going through the left side inspection plate opening.

Howsomevers; yer also reporting lifting cylinder leakage. Most would take this opportunity to replace the old 3-ring piston with the new improved NAA O-Ring piston. A much more "forgiving" and really improves lift-piston performance. $25, cheap.

These are all discussed many times before, iff'n you really wannna giffyer eyeballs a workout, do an "archive search" at the top of this great N-Board.

Otherwize, consult yer I&T FO-4 manual. $22, cheap..... ....Dell

You are probably looking at less than 40$ worth of stuff.. most of it is the 28$ piston.. etc.
