Pump drive disc for Link-Belt LS238H

The pump drive disc, part number CDHG0048, functions as a mechanical coupling within the hydraulic system of the machine. Its primary role is to transmit rotational power from the engine or power take-off unit directly to the hydraulic pump, enabling the pump to generate the necessary flow and pressure required to operate the crane's various hydraulic actuators and functions.

This component is specifically engineered for use in the Link-Belt LS238H crawler crane. It facilitates the connection between the prime mover and the hydraulic pump assembly, ensuring that power is transferred effectively to support operations such as boom movement, winch control, and slewing. Proper installation of this disc ensures the alignment and power transmission required for the hydraulic system to maintain consistent performance levels during operation.

In heavy machinery, a drive disc of this type acts as an interface between the engine flywheel or coupling housing and the hydraulic pump input shaft. These discs are often designed to accommodate minor misalignments and dampen rotational forces between the engine and the pump, which helps protect the pump input shaft and the engine crankshaft from excessive stress during startup and load changes.
