prince valve help needed

[ponyexpress976]

I got a tw-6 that has been leaking for a while and now spews fluid out of the back of the auto return valve. Tightened the allen head bolts and that seemed to help but did not totally stem the tide. Given the dirty location I didn't want to tear it open. Is there an internal o-ring or some other seal I need to fix the issue? I noticed the back cap and the adjustment block had no gasket material. Is that normal?

Spool valves are normally a machined fit, without any seals or o rings. Chances are the valve is worn.

Something that can be rebuilt or should I start shopping for a replacement?

There are O-rings at the front and back of the spool. The cover on the detent needs no seal some valves have a visible vent in the cover.

I have a TW-5 that was leaking from the controls as well when I bought it. There is an o-ring kit that you can get to replace all the o-rings in the control valves. . I just called Timberwolf and they sent me the right stuff.
