I got my B6000 with a FEL about 3 months ago and have had a few problems with the hydraulic system. The first occurred when I was clearing snow from the driveway. The bucket was full of snow and I could not quite reach over top of a 2 X 2 wood driveway marker, so I tried to use the loaded bucket to push it down a bit farther into the soil. As the 2 X 2 started to take up some of the load, it suddenly broke and the bucket dropped about 5 inches and stopped abruptly when the hydraulics stopped it from dropping any farther. Hydraulic oil started leaking out from somewhere around the oil pump. Looking more closely at the pump I could see it had cracked in the casing all along the side. I suspect when the loader dropped suddenly and came to a rapid stop, this created an oil pressure shock wave that reflected back to the pump and over stressed the pump case causing it to crack. Any thoughts on this? If there is an over-pressure relief valve on the system, I dont think its working. When my lift or curl cylinders reach the end of travel, the engine loads down and will stall completely if I dont release the control valve lever fast enough.
There is no other device on the hydraulic system that look like a pressure relief valve. Any input from you guys would be much appreciated. By the way, this is a great forum! I have learned a lot from all the members that share their know-how for the benefit of us new-comers.
P.S. - Make of the FEL and control valve is unknown.
