Pin for Caterpillar machinery

The 131-3469 pin functions as a mechanical fastener designed to join components in heavy equipment. It acts as a pivot point, allowing for the necessary range of motion in assemblies such as excavator arms, crane booms, loader linkages, and undercarriage systems. By securing these connections, the pin maintains the alignment of moving parts while managing the mechanical stresses transferred through the machine structure during operation.

This component is engineered for use in various Caterpillar machinery applications. It is designed to fit into specific pivot points and bushings where precise tolerances are required to prevent excessive play or movement within the joint. Maintaining the correct fitment of this pin is necessary for the proper function of the connected assemblies.

Pins of this type are used throughout heavy machinery to create hinge points that enable the articulation of hydraulic attachments and structural frames. They are typically installed in conjunction with bushings to reduce friction and wear at the point of rotation. Regular inspection of the pin ensures that the joint remains secure and that the machine operates within its intended mechanical parameters.
