Roll pin for Terex BT4792

The roll pin, part number 224-12001, serves as a cylindrical fastener within the throttle assembly of the Terex BT4792 crane. This component is engineered to secure mechanical parts through an interference fit, ensuring that linkages and control elements remain properly aligned during operation. By maintaining the integrity of the throttle linkage, it supports the consistent transmission of inputs from the operator to the engine control system.

This pin features a diameter of 1/8 inch and a total length of 1 1/8 inches. It is specifically intended for use in the Terex BT4792 model. Proper installation of this fastener is necessary to maintain the mechanical connections required for responsive engine speed control.

Roll pins are commonly used in heavy machinery to lock components in place on a shaft or within a housing. Their spring-like design allows them to exert constant radial pressure against the walls of the hole, which helps prevent loosening caused by the mechanical vibrations inherent in crane operations.
