I just rebuilt my 1952 Super A hydraulic cylinder block last weekend. I installed a new kit of o-rings and gaskets from the CaseIH dealer. I noticed a couple days later my control valve o-rings were leaking. So I got new o-rings separate from the kit and installed these last Friday night. It appeared these o-rings had a slight thicker wall. I thought this was going to work but it started leaking later Friday night and is still leaking. Anyone have any ideas what I can do next? I have looked all over for thicker o-rings with the 1/2 inch I.D. to match close to what the control valve requires. Everybody I talk to says they had no leaks after installing the o-rings even the CaseIH dealer mechanic. Someone recommended teflon orings but I can't see how I would stretch a teflon o-ring over the shaft.
