[QUOTE="Tazza, post: 8104, member: 82"] Cylinder creep is normal. I think the acceptable amount is a few inches per hour with no bucket attached. As for the lack of power, it sounds like you have a problem with your relief valve or a pump problem. The hydraulic system is separate from the hydrostatic system (drive). You have 3 separate pumps. Thats why your drive is fine. The hydraulic pump does act as a charge pump for the hydrostatics but that doesn't need much pressure or flow. I would start by hooking up a pressure gauge to the quick couplers and check what your pressure is. It should be between say 2,400 and 3,000 PSI. The newer machines run higher pressures than the older ones. If its way low it sounds like a relief valve problem. [/QUOTE]
