A-3908277-AI Sleeve, Wear; Front Crankshaft Seal

One New Aftermarket Replacement Front Crankshaft Wear Sleeve for Cummins C-Series Diesel Engines

This front crankshaft wear sleeve restores a clean sealing surface on the crankshaft snout, preventing front main seal oil leaks caused by wear grooves on high-mileage Cummins 6C, ISC, and ISL 8.3L diesel engines. The sleeve is pressed over the worn crankshaft journal to provide a fresh running surface for the front crankshaft oil seal, making it an essential part of a complete front seal repair on agricultural tractors, construction equipment, and commercial vehicles powered by the Cummins C-Series engine family.
