197-9251: 129.5mm Long Piston Pin

Description: A Piston Pin is a cylindrical metal pin that passes through the small end of the connecting rod and the piston skirt pin bore. It allows the piston to move freely and smoothly along the connecting rod while maintaining proper alignment. It acts as a pivot point, allowing the piston to pivot or oscillate around the pin as the connecting rod moves up and down. Attributes: • Designed to withstand the combustion pressure and piston's force on the connecting rod • Endures the reciprocating motion without excessive wear or deformation Applications: A Piston Pin is used to connect the piston skirt with the connecting rod to transfer the motion or force from the piston to the crankshaft through connecting rod in the engine, this is widely used in Cat Articulated Truck, Challenger, Gen Set Engine, Industrial Engine, Pumper, Engine - Machine, Truck Engine, Excavator, Marine Engine, Motor Grader, Marine Powertrain, and Wheel Loader.
