Flexible Shaft: Couplings R&D Marine has developed a wide range of competitively priced Flexible Couplings to fit all major installations. The R&D Flexible Couplings reduce engine noise, vibration transmission and are designed to accept propeller thrust, a separate thrust bearing and bulk head The couplings are made from a polyester elastomer which is not affected by salt water, diesel and lubrication fluids. If electrical continuity is required an earthing connector can be fitted in the centre of most Flexible Couplings. Installation is quick and easy as the R & D Coupling requires no machining and comes supplied with bolts to connect between the two existing shaft flanges. Checking alignment on installation and during service checks is quick and easy using the red cone headed bolt. Products are available ex-stock and worldwide through our distribution network. Reduces engine noise and vibration transmission Fail safe design Bolts between existing shaft Simple to periodically check Wide range of stock Accepts propeller thrust Impervious to salt water, diesel and lubrication oils Fast installation time Electrical continuity Worldwide availability Competitively priced

INSTALLATION PROCEDURE FOR R&D MARINE COUPLINGS 1. Roughly align engine and stern gear without flexible coupling i.e. only two rigid half couplings pushed together. 2. Bolt "R & D Marine" coupling between the two rigid couplings. Tightening details as below. 3. Check alignment of engine by placing feeler gauges between the RED CONE HEADED BOLT and the rigid half coupling. Repeat for the SAME bolt at 90° intervals by 4. If the gap is the same in all four positions, the engine is accurately aligned. Recommended minimum to maximum gap difference: 0.25 mm / 0.010 inch. 5. Run installation to...
