Product Description
The Cummins 3915772 OEM Timing Pin Housing Seal (rectangular ring) fits the timing pin housing on all 1989–1998 5.9L 12-Valve Cummins 6BT engines. This precision-molded genuine Cummins seal prevents oil leaks at the timing gear housing where the timing pin assembly is installed. When servicing or replacing timing pins—especially during pump timing or P7100 work—this small but critical seal ensures a proper oil-tight fit that aftermarket substitutes cannot match.
