Hi Stick on our Cat 345 Has low power pushing out And rapidly drifts back down with control in hold, however some times it will hold which makes me think it is not a piston problem more of a computer problem, any thoughts ? thank s Ken

Hello,

The controller does not control the functions, only the pump.

Could be a loose piston but, could also be a loose relief or blocking plug seals. Depends on the valve setup for this machine.

Check you antir drift relief and valve assembly first len look at the main control valve and spools. If they check good, inspect the stick cylinder next.
