First time poster-
Just bought a new used JD 7510 with MFWD- Tractor has some issues as most do with this many hours and years (10K hours), but the main one I'm concerned with is that the MFWD won't disengage. I got underneath and checked the wiring and tested for power at the solenoid- I have good power and ground. I checked the ohms on the solenoid, and I have a little over 11 ohms. Don't know if that falls in the correct range or not. Next thing I think maybe should be to change the valve that the solenoid goes onto? Unless there's a way to test for leakage in the seals in the clutch box? I also got a nice surprise when I picked the front end off the ground and I have at least 1/2" of wobble in the front axle trunnion. So that's gonna have to come out too.
Would love it if someone has some insight on how to troubleshoot this MFWD unit before I go tearing it out of there! Thanks.
