Stop oil leaks at the source with the Cummins Front Cover Seal. Pressed into the timing cover, this seal forms a reliable barrier against hot engine oil migrating past the crankshaft. It is also molded from a specialized elastomer that remains flexible through repeated heat cycles, allowing it to maintain constant contact with the crankshaft surface. That controlled contact helps prevent shaft scoring while stopping oil from reaching belts, pulleys, and the alternator. Using this Cummins 6303173 front cover seal helps maintain a clean engine bay and avoids the leaks that draw unwanted attention during inspections.
