when the hydrolics work it does a good job but for no reason they stop lifting and it raises real slow. It is full of oil, i have run front screw in and out several times thought a plunger might be sticking still no luck. Do i need to rebuild pump? Is the pump shot? Need some help

Thanks,

Chris

If it comes and goes as far as working, it might be sludge build up in the reservoir. Have you ever drained and flushed the hydraulic system. It might pay to pull the pump and clean everything up.
