Too, I have had the vanes stick and not want to pump properly right off. The first thing I'd do is look on the inlet or the outlet side of the pump and see if there is a small fitting/plug that you can remove. With the plug out pour in a quart or two of hydraulic oil, and replug the hole. I've had to repeat this proceedure several times on occasion to ever get the pump to actually pick up, but give a couple of shots of oil, it never failed to work. [Reply]   [No Email]

Do you know where someone can access a schematic of the pump & tank? I've a parts manual, but strangely, it doesn't even include the Hydraulic system (that I can find). Thanks again.

No guarantees but I do have a few of the parts books for the hydraulic systems so I'll look when I get back to the shop and see what I've got. [Reply]  [No Email]
