31R5 R & D Marine Gearbox Damper Drive Plate
Fitted between the engine and the PRM 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 31R5 Damper Drive Plate is from the R and D hammer head element range. Common applications for the 31R5 drive plate include marine engines with SAE 11.5" (11½) flywheel fixings.

- Spline: 17 teeth 16/32 DP (28.84mm diameter) for PRM 301, 302, 401, 402, 500 and 750 gearboxes.
- Diameter of back plate which bolts to the engine flywheel: 352.5mm (13.875") SAE 11½"
- Back plate fixing holes: One single set of fixing holes 8 x 10.6mm on 333.4mm pcd SAE 11.5

Fitted with the multi-directional 'R' Hammer Head element for up to 745Nm 550 ft lb torque, providing a smaller element diameter which is more torsionally flexible than the loop type elements and provides three stage stiffness with up to 9 degrees of deflection. The 31R5 damper drive plate is also failsafe.
