Description

The Cummins Rod Bearing Set 3802071 (0.25 mm undersize) is a precision-engineered replacement designed for diesel engines with reconditioned or lightly ground crankshaft journals. This bearing set directly replaces Cummins OE part number 3802073 , ensuring OEM-correct fitment, proper oil clearance, and reliable long-term performance. Engineered for use in Cummins diesel engines , these 0.25 mm undersized rod bearings are ideal when standard bearings can no longer maintain correct clearance due to minor journal wear. They restore smooth crankshaft rotation, reduce friction, and support consistent engine balance under heavy-duty operating conditions. Manufactured using high-quality bearing materials with advanced overlay and backing construction, the Cummins 3802071 rod bearings provide excellent load-carrying capacity, fatigue resistance, and oil film stability. Precision-machined shells ensure accurate sizing and uniform contact across all connecting rod journals.
