Cummins®

The Cummins 3016650 Piston Pin is a critical component in heavy-duty truck engines, essential for efficient engine operation. This part connects the piston to the connecting rod, facilitating the reciprocating motion necessary for engine function.

Basic Concepts of Piston Pins

A piston pin, or wrist pin, is a cylindrical component that links the piston to the connecting rod within an engine. It allows the piston to move vertically while the connecting rod rotates, converting linear motion into rotational motion. Piston pins are available in floating and fixed types, each suited to different engine designs and applications. Floating piston pins move freely within the piston and the small end of the connecting rod, reducing friction and wear. Fixed piston pins are secured in place, providing a more rigid connection ¹.

Purpose of the 3016650 Piston Pin

The 3016650 Piston Pin plays a significant role in truck engine operation by connecting the piston to the connecting rod. This connection enables the piston to move up and down within the cylinder while the connecting rod rotates, transferring the piston’s motion to the crankshaft. This reciprocating motion is fundamental to the engine’s operation, allowing it to generate power ².

Key Features

The Cummins 3016650 Piston Pin is characterized by its precision engineering and material durability. Crafted from high-quality materials, it is designed to withstand the high stresses and temperatures within an engine. Its precise manufacturing ensures a perfect fit within the piston and connecting rod, minimizing friction and wear. Additionally, the pin may feature unique design elements that enhance its performance and longevity, such as a polished surface to reduce friction or a specific coating to improve durability ³.
