[auctioneeral]

ford 1920 3pt. hickups,oscilates up and down. After reading posts on here, It sounds like it maybe the lift piston seals.
Does anybody have service manual were they could send me pages of the detail of the 3pt lift piston. I have found online
drawing of lift piston area of part numbers. But I have not yet started to tear it apart yet.

I'm going with piston seals. There's no mystery in there. Just start unbolting it. On my 3910 the unit was heavy enough that I used a cherry picker to install it after cylinder repair.

Service manual says replace all O rings and seals so I would get the rocker arm rings and seals also.
