Hydraulic O-Ring Leak

Jim Sedgewick · Feb 11, 2014

I have a 1957 IH 350 Utility. The high and low pressure hydraulic tubes coming from the pump into the seat area are leaking hydraulic oil. I replaced the o rings with some I had on hand. There is still a leak Where the tubes come into the seat area. Does anyone know if a certain kind of o ring is required? Any help is appreciated.

Be careful to be sure it is the surface between the flange and casting that has the leak. Many have cracked at the tube to flange (crack in the tube) and some have had issues at the braze of the tube to the flange. THere are Teflon rings available from Motion Industries and Kaman https://ec.kamandirect.com/us/index.jsp
You will need the ID and section diameter. Jim
