The hydraulic pump on our 980G recently went bad, so we replaced it with a new pump straight from our Cat dealer. As soon as it was installed both the tilt and lift have been drifting quite noticeably. Before the old pump went bad, this loader had no cylinder drift at all. We have looked into the main control valve, ride control accumulator, now they are thinking of re packing the cylinders. Is there anything else we could try?
