leaking touch control??

Thu Jan 24, 2013 11:03 am

Hello People,

I have recently purchased a 1952 Cub and i think I have a leak in my touch control unit i think its leaking into my engine oil. I have filled the unit up to the fill point but after a while i have to add more Hytran to the unit and my motor oil has taken on a milky color. If I do have a leak were would it be coming from and is it a fairly easy fix. This is my first tractor and Im new tho this so any help is great...

That is a common problem. the seal or O-ring on the shaft of the pump lets it leak into the front of the crankcase. There are a couple of videos in the How to section on fixing it.

From your description, it sounds pretty certainly that your hydraulic pump is leaking. When it leaks, the fluid ends up in the crankcase with your engine oil. I would say that an overhaul of the pump is needed.

Assuming that the leakage is at the shaft seal, then you would need to replace the O ring. Stock# HY396
touch control pump
drive shaft o-ring

I think he has another problem also. He said his oil was milkey also.

If the milky did not appear till he started losing TC fluid and gaining crankcase level, might it be contamination in the TC unit? I know when I changed my TC fluid for the first time after sitting up for over 25 years,(the tractor, not me) I drained out some curious jelly-like substance along with the fluid. Maybe this could cause the oil to appear milky.

HY288 is the one for the pump. some of the earlier ones had a seal rather than an o-ring., but a 52 probably has the o-ring
