I took the live pump off my D and looked it over carefully. The governor side bearing had worn to .013" oversize, so I turned and bored a new one and pressed it in. Then I replaced the oil
seal, put it all back together and gave it a test. No good. It was slightly better but still very slow and weak. Again, if I pressurize the reservoir with compressed air, the hydraulics
operate fine, and the cylinder moves fast; but as soon as I take the pressure away, it's back to slow motion and no power. It couldn't even raise the plow.
So today I took it off again (I'm getting fast at this!) and took it apart so I could see the distributor's side seal. The previous bozo had welded the gear through the snap ring to the
shaft, so I had to do some careful grinding to remove it without during the shaft. I did very well and got it apart without hurting the shaft, I'm proud to say. I can see no place where
this thing is leaking. As far as I can tell the two seals are solid. Yet, oil comes out there when I pressurize it.
Now I cannot get it the rest of the way apart. The spring inside and the lever are in there, and I can't figure out how to pull them out. Darn, I hate stupid engineering like this.
Ridiculous modern stuff anyway. Grrr! Does anyone here have a suggestion who I could send this thing to to be rebuilt? I have to make a living in that shop, and this D is taking way
too long.
Or does anyone have a rebuilt one I could buy that I could trade this pump for? I'm at the end of my ideas and getting sorely frustrated.
Thanks for any help at all.

P.S. I showed my email, so feel free to type directly if it's easier.
