I have a clark TMG 20 (sit down) Hydraulic lift function is very slow. could it be a fluid divider issue or possible pump going out. Im used to hearing the motor run faster as it lifts, stay at a low speed now the whole time. No codes. Can you help??

Are the switch's on the hydraulic control levers ok? is it making good contact and adjusted properly? How is the pump motor itself are the brushes good and motor cables tightand in good condition,is it getting full voltage?
Is the spool in the control valve getting full travel up and down when you use the control lever for lift/down?
Ok im gonna look into that. No. The tilt and side shift work normal- just lift function.
Have you checked the lift potentiometer as this is what controls pump speed when lifting. TMG machines had a separate power steer motor so are not fitted with any flow or priority valve. Are all hyd functions slow?
