Ron, if you have any screens or strainers in the hydraulic circuit, check to be sure they are clean. Duall loaders are noted for using cut tire sections for their seals in the cylinders. This along with the fact that you may or may not be using HY-Tran for the hydraulic fluid in your system, or something similar, eats that rubber up like it's going put of style. Seen many strainers on the 300's,350's,400,s etc, plugged so solid that it collapsed the screen in the reservoir. Make a thorough check of the system. Oil will get hot at ambient temps., but not to the extent you describe. One other thing to check might be? Has the pump been getting slower? It may be that you have an internal leak in one of the cylinders. This would cause a reciprocal reaction to the function of the loader.I still believe you have a restriction in the system. I wish you good luck.
