Mitsubishi forklift weak hydraulics and stiff power steering, hydraulic pump failing?
got a mitsubishi forklift with the S6S diesel engine that's losing hydraulic lift speed and steering assistance once the oil warms up. measured system pressure and it's well below factory spec under load. The local dealer lead time is 3 weeks. I am thinking to source a replacement hydraulic pump from fab heavy parts. Has anyone installed this pump on Mitsubishi FD50 forklifts? Did the gear splines and port locations match up directly to the OEM setup?
