1964 Ford 4000 Industrial with PTO and Hydraulic issues

Rosastringworks · Apr 29, 2014

I have a 1964 Ford 4000 Industrial model with 4 speed transmission. It also has a lever on the left side for selecting low, standard, and high range. Which in effect gives 12 speeds forward and 3 reverse. My dad bought it slightly used in about 64/65. It has always been a good tractor, but it sat for about 15 years in a shed. The engine was froze, the clutch was bad, and all the sheet metal rusted off it. I am pretty handy so I basically took it apart and replaced or repaired most everything I could see or think of. Including the clutch, brakes, radiator, fenders, etc.. I converted it to 12 volt and repainted it. It looks and runs great.

Here's the bad news. When I swept the floor after getting it all back together and running great, I found an o-ring on the floor in the sweepings. The o-ring is about 1.5 inches in diameter (just by memory, didnt measure it). I don't really know where it came from for sure. However the lift arms don't work and the PTO will not work consistently, and when the pto does turn, you can literally grab it and stop it by hand. There are no noticeable sounds or whines.

I have removed the Allen plug from the pump and oil does flow out. My suspicion is that the o-ring went around the hydraulic lines where I broke the tractor apart to replace the clutch. Could that be the reason why both the lift arms and the PTO do not work. I would really appreciate some assistance as I have no real idea as to what to try first.

I have tried to look at the parts manual and the repair manual for ideas, but they don't seem to address the "o-ring" issue. Please help! Thanks very much, Jerry Rosa, rosastringworks@gmail.com
