49AD5 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, this Damper Drive Plate is from the R and D range. Common applications for this drive plate include SAE 11.5 flywheels mated to PRM301, PRM302, PRM401, PRM402, PRM500 & PRM750 gearboxes.

The technical details:

This type of plate is especially suited to workboats with slow speed applications & pleasure boats. Note that this type of damper drive plate can only be fitted to rotate in the standard direction of rotation (anti-clockwise when looking at the flywheel) with the element facing the gearbox. The 49AD5 damper plates are also failsafe.
