21R5 R & D Marine Damper Drive Plate
Fitted between the engine and the gearbox input shaft, a damper drive plate is designed to transmit the engine power to the gearbox, whilst reducing transmitted gear noise and providing a cushioned drive when selecting gear. All R and D Damper Drive plates include a 'failsafe' design.
Also called the Driven Plate, Damper Plate or Clutch Plate, the 21R5 Damper Drive Plate is from the R and D hammer head element range. Common applications for the 21R5 drive plate includes engines fitted with the PRM 601 or PRM 1000 gearboxes, SAE 11½.
