22A4 Boat Engine Damper Drive Plate from R&D Marine
Fitted between the 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 22A4 Damper Drive Plate is from the R and D Loop element range. Common applications for the 22A4 drive plate include small marine engines which have a flywheel with the 6.125" diameter fixings aperture.
R and D drive plate technical details:
- Spline: 10 teeth B10 x 23 x 29 DIN 5464 (29mm diameter) for PRM 80, 120 & 150 gearboxes, Hurth ZF & HBW, Technodrive TMC 30 & 40 gearboxes and the Borgwarner 500.
- Diameter of drive plate back plate which bolts to the engine flywheel: 155.45mm (6.125")
- Back plate fixing holes: The small back plate has 5 x 6.35mm holes (0.25") on 142mm PCD (5.593). This was a very common fixing arrangement for BMC, Leyland, Thornycroft and Perkins engines
- Drive plate maximum thickness: 32mm (1.25")
Fitted with a type A loop element for 80Nm 60 ft lb torque, which can be mounted either round on the flywheel and rotated in either direction. This drive plate element will provide linear stiffness up to 3 degrees of deflection and is failsafe.
