Hi All,
I am new to this very informative site and hope that you may be able to help me understand my problem.
At work, we have a M5030 (11 years old) with a loader. On Monday, hydraulic fluid filled the crankcase to the point of overflow. Suspecting a faulty hydraulic pump, I called the dealer and they advised that a seal kit would cost 20 - 30 dollars or if it was a bad pump, it would cost around 1000 dollars to replace it. We decided to try and replace the seals on our own to see if that would correct the problem. There was one demolished internal seal and the seal that is on the outside cover around the shaft was torn allowing the fluid to get to the engine. After replacing the seals, we bolted the pump back on and cranked the tractor. The loader worked flawlessly, but now it has no steering. In fact, the steering wheel will turn with no friction and has no stopping point.
It appears that the pump is a two section unit, one controlling the loader and 3pt. hitch and another that controls the steering. I took the pump apart again, but I don't undersand how the fluid gets to the section of the pump that powers the steering.
I know just enough about hydraulics to get myself in trouble and would appreciate any feedback that you may have. Worst case, I will take it in next week, but I hate to be stumped. Thanks for your advice.
