The relief valve is NOT adjustable, and we have already tried a new one. It didn't help at all. Yes the performance gets worse as the oil warms up. Does this mean the pump needs replaced? is it the pump that we have been told is called the "prime pump"? If so, where can I get one cheap?
I have a LS 180. It is a 2001 and has been a great machine. Recently it has had a loss of hydraulic pressure when lifting and bucket tilting back. It used to lift over 3000 pounds easily, now it has trouble lifting 500 pounds. We put a pressure gauge on the aux and its only reading 1600 pounds...
