I have a 656 gear drive that has lost hydraulic power to the power steering, loader and 3 pt. I guess there is a small amount of pressure as the 3 pt. will slowly lift the mower about a foot after several minutes.
I've inspected the check valve screen and filter and they looked OK. What can I do to check the pump? What else could be wrong? What else can I check?
I may have found something. Last night I took the pump out removed it from the flange. The two o-rings between the pump and the flange were gone. That could explain why there is no pressure on either main and hitch systems.
Glad to hear you got it going again. Don't be a stranger!
