I have a T550 with about 1200 hours on it. I have a service manual as well. My T550 works fine except that the lifting capacity seems to be low. At low rpm the bucket hardly moves up, full throttle it moves pretty good. With a full load of dirt no movement at low rpm and sometimes can't lift it at full rpm. The bucket tilt is very similar but not as bad. I changed the hydro oil recently. I adjusted the pedal linkage. Would the main relief valve cause this? This doesn't make sense based on the more power at higher rpm. Could one of the lift arms be leaking internally? I have some oil around one of the lift arms but I was thinking I filled the hydro oil too full and it was leaking out the side. My sight glass is unreadable(it just is clear) . Thanks for your help!
