    Posted: 03 Jun 2012 at 11:57am
I have an i600 with a backhoe and loader. It was not running when I bought it but have it running now. When any of the cylinders come to the end of there stroke on the hoe or the loader it will stall the engine like there is no pressure relief at all. The loader valve pack is a cessna not sure if the hoe is the same. Dose anyone know if the relief valve is adjustable and what kind of pressure it should be set to relief at.    Thanks Clem

there are relief valves in the system,the first one you need to check is in the loader valve. i don't know if its adjustable,but to check it there is a port on the bottom of loader valve. with a gauge installed in this port roll loader bucket all the way. should be 2250 psi. CAUTION don't over do it here if relief is stuck and stalling engine like you say, it can destroy the pumps internals. there are other circuits to check but start here.  i was able to find a used valve  for mine   good luck
