I bought a old Massey Ferguson MF30 industrial tractor. When I bought the tractor, the seller said the tph did not work, but a seal kit was about three hundred to fix it. he also said, if you raised the hitch to high, it would blow the seal again. It wasnt the seal. Its blowing the valves out of the internal hydraulic pump, Twice so far. It only does it when the hitch is raised to the top and I cant afford to keep replacing pump parts. Could it be the relief valve? It cant be that simple and I hate to blow apart another pump. Any help would be greatly appreciated.

UncleBuck,

It sure sounds to me as though the relief valve may be the problem....but I'm wondering if it's even still there?

You may want to do some investigating. I'm almost willing to bet that the relief valve was sticking open, or leaking, so somebody removed it and plugged the port.

I think you're on the right track. It could be that simple.

UncleBuck,

I believe I've found the proper part for you, but you might find one cheaper somewhere else.

See the link below.

Thanks for the advice. The relief valve is still there but i did not think to look in the port itself. The valve did have a small piece of metal in it that I cleaned out the time before it blew last. Fortunately it's sitting on the shelf in the garage waiting for new chambers so Ill have to go check the ports. Thanks for everything.
