Cummins®

The Cummins 3377249 Cam Repair Bushing is a specialized component designed for the maintenance and repair of heavy-duty truck engines. This part is integral to ensuring the smooth operation of the engine by addressing wear and tear on critical components such as camshafts and lifters. Its role in maintaining engine performance and longevity makes it a significant part of engine maintenance routines.

Basic Concepts of Cam Repair Bushings

Cam repair bushings are components used to repair and maintain the camshaft and lifter interface within an engine. They function by providing a smooth surface for the camshaft to rotate against, reducing friction and wear ¹. These bushings interact directly with the camshaft and lifters, ensuring that the motion transmitted from the camshaft to the lifters is efficient and consistent. This interaction is vital for the proper operation of the valve train, which controls the opening and closing of the engine’s valves.
