Yep, that is what my valves look like. I did read through the trouble shooting pages but didnt find anything that i had not already thought about. I talked to a buddy at bible study tonight who brought up an interesting thought which he had happen to some equipment he owned in the past. He said the feed line to the pump had collapsed but you could not tell until it was removed and inspected. Not sure if that is possible with the rubber line on this bobcat but I think I may look at that tomorrow. When you rebuild your valves did you find damage?
"When you rebuild your valves did you find damage? "
I had pitting/corrosion at the front end of the spools, and the O ring seals were worn. This caused significant leakage, but nothing that would cause a failure of the system. The whole thing is pretty solidly built.
(The O rings are more correctly called quad rings or X rings because of their sectional profile).
What I would do next is crack some pipes to see if the oil is flowing. Maybe start with the pipe between the vari-speed valve and the central manifold. In a healthy system, with everything in neutral, oil should ONLY be flowing from the vari valve to the manifold in the direction of the arrow. Nothing should be flowing towards the manifold from the main relief valve. Then you basically work backwards until you find the valve thats the problem.
