[QUOTE="skidsteer.ca, post: 10951, member: 307"] If your relief valve set screw backed off or the relief had a broken spring, the pressure would drop and the hydraulics would be lazy as you describe. It's hard to imagine it getting so bad it won't move the empty loader arms. That would be under 500 psi imo. Hooking a pressure guage into the front couplers would confirm if there is a lack of pressure (generally 2250 to 3000 psi) A worn out pump would act the same but get worse as the oil warms up. If you idle the engine and move the foot pedals does the engine labour at all? like its trying to do some work. If you have no pressure the engines tone/sound should not change. Ken [/QUOTE]
