12AA87 R & D Marine Volvo Engine Damper Drive Plate

Fitted between a Volvo Penta boat 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 12AA87 Damper Drive Plate is from the R and D High Deflection element range. Common applications for the 12AA87 drive plate include the Volvo Penta MD2010, MD2020, MD2030 and MD2040 when fitted with PRM Delta gearbox.

The technical details:
Spline: 17 teeth 24/48DP (19.7mm diameter) for Newage PRM Delta gearbox.
Diameter of drive plate back plate which bolts to the engine flywheel: 175 mm 6.89"
Back plate fixing holes: This drive plate was designed for the Volvo 2010, 2020, 2030 & 2040 marine engine flywheels, 6 x 1/4" holes on 163mm PCD (6.417")
Drive plate maximum thickness: 32mm (1.25")
Fitted with the softer type AA high deflection element for 135Nm 100 ftlb torque, providing a maximum deflection up to 30 degrees. This type of drive 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 drive plate element facing the gearbox. These damper plates are also failsafe.
