[QUOTE="Dirty70Bird, post: 119696, member: 18459"] I suspect the pressure relief valves on the hydraulic pumps have some dirt in them. There are 4 of these valves, 2 / pump. They are located behind some large hex caps 1 3/16 IIRC. I have a similar issue, and have recently figured out a way I might be able to disassemble them to clean them properly. I have had them out of my machine, but to disassemble, you need some magnification and small snap ring pliers, and 3 different o ring seals. I do have an exploded diagram of these pressure valves that I could send. The o rings are standard size o rings and cheap at a hydraulic shop. Otherwise replacements are available for around $300 each. [/QUOTE]
