22AM4 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 22AM4 Damper Drive Plate is from the R and D High Deflection element range. Common applications for the 22AM4 drive plate include BMC, Ford and Perkins engines which have a flywheel with the 6.125" diameter fixings aperture.
Drive plate 22AM4 can replace PRM drive plate MT4907 and R&D drive plate 22AA4.
Clutch plate technical details:
- Spline: 10 teeth 1" SAE spline (29mm diameter) for PRM 100, 101, 140, 160 & 260 gearboxes, ZF 10, 12 Hurth HBW 35, 50, 100, 125, 5 & 10 gearboxes, Technodrive TMC30, 40, 50 & 60 and the Borgwarner 500 gearbox.
- 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 the softer type AM high deflection 'finger type' element for 135Nm 100 ft lb 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.
