I have a customer with a fleet of Hyster E50Z-33 (G108) forklifts. All of these lifts are AC drive but DC hydraulic motor. The fleet is getting old and tired (20,000+ hrs). Over the last year or two they have been going through a lot of hydraulic pump motors. The operators are terrible at not locking out the units when the brush wear indicator code comes on the dash, which doesn't help. I have gotten a few of these motors rebuilt locally with relatively poor results, reman motors have held up better. The motor failures are always the same, brushes worn down to nothing and burn up the commutator. Anybody got any ideas for anything I might be missing that could be causing this?
