Clark CEM 16S:
Hydraulic pump outages

Hello everyone,

Clark is not my ususal brand to work on, so i don't know the usual problems.
My customer has a Clark Cem16S 2001, sometimes the hydraulic pump works fine for lifting, tilting and shifting, and sometimes nothing happens when you opperate the lift-, tilt- or shift-stick. Only when i touch the drive pedal, the pump runs slow for steering. The signals from switches and potentiometer from lift,tilt and shift-stick are fine.
I suppose that this problem is caused by the pump electronics. But it's a bit expensive to just change. I hope that anyone recognize this problem and knows the answer to solve it.
