Farmall 100, touch control internally leaking

Patrick Martin · Apr 28, 2011

Hey, been a long time since I've posted here.

Has anyone figured out where these leaks are coming from?
My touch control unit is still not picking up loads like it's supposed to.

It's not leaking externally or in the engine but somewhere internally and the fact is I put a fresh kit in it.

It'll pick up and then slowly bleed down with a load on it. Pistons and cylinders are nice.

Check valves that lock the pistons in place are leaking. Did you just put a seal kit in it? If so did you get the plastic check valves, their operating pistons and their sleeves put in correctly. Also, thermal relief valve might be leaking.

Suction side air leaks can mimic other issues and be difficult to find. Pressurize the reservoir with 20psi, and see if there are leaks with spray detergent, like a leaky tire. orings and cracks at fittings are possible. Jim.
