Hey, I have a 1967 Clark C 20 B has been a good little forklift for the last five years. I've had it never really did any kind of maintenance on it. The cylinder has always leaked. I'm just getting tired of always cleaning up the garage floor, so I took the chains off, started disconnecting the hose, but And I tried to hoist it out with a cherry picker, but apparently there's some plate that slides underneath the forklift that keeps that from happening, so I need to take the carriage off. Does anybody have any experience with this or could help me locate a service manual? I've looked online and I really don't see anything. I see operators manual, but I don't see any real repair manuals..
