[QUOTE="OldMachinist, post: 3252, member: 437"] The machine has a little over 1700 hrs. on it. I bought it from a rental company and it had a few other problems that they couldn't figure out also. It had one wheel hub that kept coming loose and I found that the hole in the axle hadn't been tapped deep enough from the factory. One foot pedal would jam up sometimes and found that to be someone used the wrong hardware to hook the pedal to the seat bar interlock. But the cavitation was only a minor problem when I got it and it just kept getting worse. I should note that what Bobcat calls the seal kit for this hydraulic pump I would call a rebuild kit. It contains a new wear plate, diaphragm, gasket, seal, check ball and spring. So you replace every thing except the gears and bushings in the pump. Also the service manual says you can service the pump without removing the engine. I wouldn't recommend doing it that way but it says you can do it. Don [/QUOTE]
