Upgraded Oil Pump Valve for Harley Davidson

For 1957-1976 Ironhead Sportster

• HD.M.G.I. has devised a solution for the problem of oil accumulation in the crankcase in engines manufactured before 2000.
• The steel ball does not always seal the oil pump's feed hole, causing the oil tank to empty into the crankcase when the engine has been stopped for some time.
• The solution consists of a special ball made of FKM 70 ±5 Shore (Viton) material, which withstands oil and temperatures from -25 to +230 degrees Celsius.
• The complete kit includes the ball, a special spring, and an aluminum adapter that is placed between the spring and the ball.
