My steering hand pump is leaking profusely out the side of the case. Now, it was fine but, I am just finishing the install of a new clutch and TA. I also rebuilt the MCV with new springs, seals and gaskets. Upon starting the tractor I tried the brakes and turned the wheels fully both directions then I drove it a bit without issue until we noticed the oil leaking from the steering motor. I doubt this is a coincidence so what have I messed up? I checked the oil pressure at the dump valve port and it is 290 psi. I checked the lubrcation pressure and it is 22 psi. I have put new seals in the hand pump. And I checked the tolerances within the pump and they appear good. After reassembly all looked dry and fine until about the 6th time I cranked the steering wheel completely to one end and oil again sprayed from the case outer seal. My guess is something in the MCV is hanging up and causing a pressure spike. Do you have any ideas where to look? Thanks in advance
