This R & D marine damper drive plate is 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, the 42AN49 damper drive plate is from the R and D high deflection element range.

Common applications for the 42AN49 drive plate include SAE 7.5 flywheels mated to gearboxes with 26 teeth spline, Borgwarner Velvet drive 70, 71, 72, 73 C, PRM inline gearboxes, Paragon P series, Technodrive TM93, TM170, TM26, TM345, TM485, TM545, TM880, TMP1200 & 1500, Twin Disc, Volvo MS, HS1, 270-280 leg, ZF Hurth HSW and IRM220 gearboxes.
