Product Description
Cummins 3915772 OEM Timing Pin Housing Seal (Rectangular Ring) – 5.9L 12-Valve (1989–1998)
The Cummins 3915772 OEM Timing Pin Housing Seal is a genuine Cummins rectangular ring seal designed for the timing pin housing on 1989–1998 5.9L 12-Valve Cummins engines. This small but critical seal helps prevent engine oil leaks around the timing pin housing and timing gear cover, ensuring a proper seal during timing adjustments, injection pump service, and front gear housing maintenance.
Whether you're replacing a worn timing pin seal during a P7100 timing adjustment or servicing a VE-pump-equipped 12-Valve Cummins, the OEM Cummins 3915772 seal provides the proper fit, material quality, and long-term reliability that aftermarket substitutes often lack. Replacing this seal whenever the timing pin housing is removed helps prevent future oil leaks and maintains factory sealing performance.
