Clutch disc for Grove RT 522

The clutch disc 9904103635 serves as a primary component within the transmission system of Grove cranes. It functions by engaging and disengaging the engine from the transmission, which allows the operator to regulate the flow of power to the drivetrain or lifting systems. When pressed against the engine flywheel, the disc transfers engine torque to enable controlled movement of the machine.

This part is compatible with Grove RT 522 and TR522 rough-terrain crane models. It is engineered to fit specific transmission configurations used in these units, including those identified by serial numbers 45805 and 48137. The disc consists of a metallic core with friction material applied to both sides to facilitate the transfer of torque during operation.

In heavy machinery, the clutch disc acts as the interface that manages the connection between the power source and the gear train. By controlling the friction contact, it allows for smooth transitions during gear changes and prevents engine stalling under load. Regular inspection of the clutch assembly is necessary to ensure the disc maintains proper contact with the flywheel and pressure plate, which is essential for maintaining the intended power transmission efficiency of the crane.
