Touch Control Leak on Farmall C

A while back, I posted a question regards repairing a leak from the control valve on the Touch Control unit on my Farmall C. I wondered if it could be done without removing the unit from the tractor. New boots and O rings now installed in the control valves and they seem to be holding. Old O rings were there, but flattened and hard. As to replacing with the unit on the tractor, I think that would be about impossible. I ended up removing it and doing the work on my work bench. Also, I determined that the cavity around the cylinder rods is the domain of the mud daubers. Don't see how a little insect can haul so much dirt! There was only space for the mechanism to move. Everything else back in there was full of mud dauber nests. You really can't get back into that area until the unit is off the tractor.

Haas, I remember your post, and think I replied. I found out the same thing you did. I tried for an hour to get it apart with the unit on the tractor and gave up, as I had some work to do with it. I just filled up the unit and went back to work. I am going to have to remove the unit and install soon though. I only bought one boot and o ring but since I am going to have to remove the unit I am going to go ahead and do both.

You may also need gaskets for where the pump manifold connects to the Touch Control unit and for the filter screen. I was able to sucessfully reuse the filter screen gasket, but needed the one for the manifold. Also forgot to mention that in order to get the control valves out, you have to remove the big bolts that hold the rockshaft arms and push the rockshaft assembly out of the way to get the control valves to come out. It probably be a good idea to pull the pistons out of the cylinders and put new boots and O rings there too. I did not do that, as I had not ordered the parts and there was no sign of a leak. My unit still had the original leather boots on it.

Haas, It is very refreshing to read about how the problem was finally solved. All too often we don't know if our suggestions worked or not.
