Hello everyone, have searched this site for info on P/S leak but havn't found much information. Hope I'm not repeating someone else question. I just bought a 1965 MF 135 tractor with a gas engine. Was told the tractor hasn't been run for more than 10 years. Hoping to do a good restore on it.
Got it running with very little work, but no power asst. on steering. Filled P/S pump, and all the oil got pumped out of a litle vent hole in top of steering column. Pulled column and replaced o ring and seal, as soon as I started the engine, seal popped and started leaking again even before I could turn the steering wheel.
Pulled the return line at pump, good flow coming back to pump, pulled control valve, can't see any visible cause in valve. Anyone know what I should look for next. Thanks for the help in advance.
This tractor does not have seprate hyd rams at each front wheel, the asst. ram is tied into the back of the steering gear. Thanks. Pat
