HI : Hope someone can help/ I picked up a Genie Z454/22 manlift at auction. I have most everything working other than only one drive wheel will spin. THe other one literally seems locked up THe one that moves i can nudge back and forth a little bit . THe other is frozen solid. I put it into free wheel mode and nothing. IU am hoping that the hub is just locked up from sitting a long time if its not that then it must be the motor ? Form what I can tell if hydraulic fluid is going to one wheel it should be goin to the other ie there are no valves etc that directs flow left or right it just looks like the directional valves are forward and reverse. I am going to pull the wheel tomorrow . ANyone have any other suggestions ?
