Product Description
Cummins Main Bearing Set 3800298 is a standard-size crankshaft bearing kit designed for compatible Cummins ISX and QSX 15-liter diesel engines.
This complete set includes seven upper main bearing shells, seven lower main bearing shells, and four crankshaft thrust washers. The bearings support the crankshaft, reduce friction between rotating components, and help maintain proper oil clearance during engine operation. The thrust washers help control crankshaft end play.
Used in select Cummins ISX dual overhead camshaft (DOHC) and ISX15 engine configurations, this set is suitable for engine rebuilding, crankshaft servicing, and repairs involving worn or damaged main bearings.
