Hi gang,
I have an Allis WD that developed a hydraulic problem, I'm hoping somebody here can let me know that I missed something obvious?
It came to me with a 3rd-party loader, and I've used it for snow removal and dragging my driveway & trails for 7 years now, so I'm pretty familiar with it. The lack of power steering combined with heavy snow in a trip-bucket over a tricycle front made me wanting a better snow solution, so I picked up a rear blower and a 3-point add-on kit from OK Tractor.
After I installed the 3-point add-on hardware, I had no hydraulics. I hadn't touched anything hydro yet, the tractor was backed into the shed & I was planning to nose it in, remove the loader, then tweak the hydro so it would run the rear 3pt instead of the bucket, but the bucket wouldn't raise.
So I took apart the pump. I ordered new springs & gaskets before I took it apart, just assuming a spring had broken. When I got it broke down, the springs were fine (replaced them anyways), the only thing I noticed was a bunch of gunk. Hoping that it was just clogged, I scrubbed everything & put it back together. Since I was at it, I also replaced the lines going to the rear cylinders.
I have the Service Manual, Operating Instructions, & Dealer Parts Catalog, I went though all 3 looking for any clue. I have tried every combination of screws A/B/C/D, plates locked, plates unlocked, etc, etc, etc, to no avail. I even took off the line to one of the rear cylinders, no fluid comes out. It's obviously bypassing or clogged somewhere, but I'm at a loss on what to try next. Any and all advice is greatly appreciated!
