Piston pin for Caterpillar 320-D

The piston pin 0947134 serves as the mechanical link between the piston and the connecting rod in an internal combustion engine. It facilitates the oscillatory motion of the piston within the cylinder, allowing the connecting rod to translate this linear movement into the rotation of the crankshaft. This component is engineered to withstand the compressive and tensile forces generated during each combustion cycle.

This part is compatible with the Caterpillar 320-D excavator. It is designed to fit within the engine assembly of this specific model, including units with serial number FAL00458. The pin ensures the correct alignment and movement of the reciprocating engine components.

In any internal combustion engine, the piston pin acts as a pivot point. It allows the piston to tilt slightly as the crankshaft rotates, which is necessary to accommodate the angular motion of the connecting rod. Proper installation and lubrication are necessary to ensure the pin functions correctly within the piston boss and the connecting rod small end.
