Cummins®

The 181027RX Valve Tappet, manufactured by Cummins, is a component designed for use in heavy-duty trucks. Cummins, a well-established name in the automotive and heavy-duty truck industries, produces this valve tappet to enhance the operation of engines in demanding applications. Valve tappets play a role in the internal combustion engine by facilitating the transfer of motion from the camshaft to the valves, ensuring precise valve operation ¹.

Basic Concepts of Valve Tappets

A valve tappet, also known as a lifter, is a mechanical device within the valve train of an engine. Its function is to convert the rotational motion of the camshaft into linear motion to open and close the engine’s valves. Valve tappets interact with other components such as camshafts, pushrods, and rocker arms to achieve this. There are several types of valve tappets, including solid, hydraulic, and mechanical tappets, each with distinct characteristics and applications ².

Operation of the 181027RX Valve Tappet

This Cummins part operates by receiving motion from the camshaft and transferring it to the valves through the pushrods and rocker arms. This mechanical process ensures that the valves open and close at the correct times, maintaining the engine’s valve timing and clearance. The precise operation of the 181027RX Valve Tappet is vital for the efficient functioning of the engine ³.
