Hi all,
I'm completely new to forklift trucks so apologies in advance for my lack of knowledge.
I've purchased an Hyster H50j 1983 serial# F003A02645D which ran ok on a concrete yard when I went to view it but on getting it back to my yard which is a bit rough it struggled in the ruts and on a shallow incline. The engine runs great and the mast lifts OK.
So far (after looking through discussions primarily on here) I have dismantled the inching valve and replaced seals, that seemed to give a slight improvement, but not managed to get hold of a gauge to test pressures yet.
Took the front wheels off to clean the breaks as the seller said he felt they were binding a bit, wheels turned by hand afterwards but on putting back on the floor and trying again seemed to have less go than before?
Emptied the hydraulic tank and transmission (I think... the casing between the engine and the differential?) as it was suggested that the wrong oil might be an issue. I have found a filter set inside the hydraulic tank. This contained quite a lot of silvery swarf which was suggested by a local tractor centre might be the remnants of an hydraulic pump that possibly failed in the past and not been cleaned out properly? I've ordered a new filter. The supplier said there should also be transmission filter but I've not been able to find one? any indication of it's location (if it has one) would be great.
Other discussions suggest a clutch pack or torque converter problem but I think these may be beyond my abilities.
Thank you in advance for any help.
