Cummins®

The Cummins 3092572 Piston Pin is a component designed for use in heavy-duty truck engines. It plays a role in ensuring the efficient operation of the engine by facilitating the connection between the piston and the connecting rod. This component is integral to the smooth and efficient movement of the piston within the engine cylinder.

Basic Concepts of Piston Pins

A piston pin, also known as a wrist pin, is a cylindrical component that connects the piston to the connecting rod in an internal combustion engine. Its primary function is to allow the piston to move up and down within the cylinder while the connecting rod converts this linear motion into rotational motion at the crankshaft ¹. Piston pins come in various types, including floating and fixed pins, each suited to different engine designs and applications. Floating pins are free to move within the piston and small end of the connecting rod, reducing friction and wear. Fixed pins, on the other hand, are secured in place, offering a more rigid connection ².

Purpose of the 3092572 Piston Pin

The Cummins 3092572 Piston Pin is specifically designed to enhance the operation of truck engines. It facilitates the connection between the piston and the connecting rod, ensuring smooth and efficient movement. This component allows for the precise transfer of force from the piston to the connecting rod, which is crucial for the engine’s performance and durability.
