□amper Drive Plates R&D Marine has developed a wide range of competitively priced Damper Drive Plates to fit most engine/gearbox combinations. The R&D Damper Drive Plates reduce gear noise and allow the engine to run Linear Stiffness elements for general applications and High-Deflection elements to stop gear noise and spline wear at slow speeds. All dampers are designed to be Fail-Safe and maintain the drive if the flexible element fails. The flexible elements are made from a Polyester Elastomer which has good heat qualities and is not affected by salt water, diesel and lubrication oils. Non-standard items are available for special installations, maximum back plate Installation is made quick and easy as the R & D Damper Drive Plate requires no machining and is ready to bolt to the flywheel. • Reduces gear noise lower speeds • Fail safe design • Machined ready to install • Elements suitable for every • Element has good heat • Special back plates up to salt water, diesel and lubrication oils • Wide range of stock • Competitively priced • No springs to rust or fret Products are available ex-stock and worldwide through our distribution network.
