Cummins®

The 3895487 Cam Follower Roller, manufactured by Cummins, is a specialized component designed for use in commercial trucks. Cummins, a well-established name in the engine manufacturing industry, produces this part to enhance the performance and reliability of truck engines. Cam follower rollers play a role in the operation of an engine by facilitating the transfer of motion from the camshaft to the valve train, ensuring precise and efficient valve operation ¹.

Basic Concepts of Cam Follower Rollers

Cam follower rollers are components within an engine that interact directly with the camshaft. Their primary function is to convert the rotational motion of the camshaft into linear motion for the valve train. This conversion allows for the opening and closing of engine valves at precise intervals, which is important for the engine’s combustion process. Roller-type cam followers, like the 3895487, are specifically designed to reduce friction and wear between the camshaft and the valve train components. They achieve this by rolling over the cam lobes instead of sliding, which minimizes contact stress and enhances the longevity of the engine components ².

Purpose of the 3895487 Cam Follower Roller

The 3895487 Cam Follower Roller is integral to the operation of a truck engine. It translates the motion from the camshaft to the valve train, ensuring that the valves open and close at the correct times. This precise timing is vital for the engine’s performance, fuel efficiency, and emissions control. By facilitating smooth and efficient valve operation, the 3895487 Cam Follower Roller contributes to the overall reliability and efficiency of the truck’s engine ³.
