Farmall 100 touch control

Charlie M · Sep 6, 2021

The touch control on my 100 is leaking oil so I bought a kit to overhaul the unit. First problem is how to remove the lift arms. I did the unit on my Super C last year and they came off without much effort but that thing had leaked oil everywhere possible so they weren't really rusted to the shaft. I don't see a way to get a puller on them. Is heating them to get them loose the only option or is there a trick to removing them.

Just realized I don't need to remove the arms. I'm taking the gas tank off so there is plenty of room to get into the hydraulic unit to remove it from the tractor. The arm I'm thinking about on my Super C was loose so that is why I took it off.

Even if you do not need it we had to remove the right arm and the outside left arm every time we mounted the corn picker. Dad had bull point bar that weighed about 30 pounds. I would use it to drive the arms off driving through underneath the gas tank. The mounting rock shaft was tapered and once the shaft was loosened it fell right off. We however removed these same two lift arms every year and they never got a chance to rust or seize in place.

No tricks. Just the same old standard rusted part removal techniques. Forget soaking with blaster, that will take years, if it ever works. Heat is going to be the quickest way to get them of, and probably the least traumatic to the parts. They're cast so heating them won't change their strength any, far as I know.

I was thinking coming through from the opposite side with a long drift once you get the arm heated up. Looks like LMack uses a simliar technique.
