Flexible Shaft Couplings

1 Flexible Shaft Couplings For engines 5 to 1500 HP Reduces engine noise andvibration transmission Fail safe design Bolts between existing shaftflanges Requires no machining Simple to install Simple to periodically checkalignment Wide range of stock Accepts propeller thrust Impervious to salt water,diesel and lubrication oils Fast installation time Electrical continuityavailable Worldwide availability Competitively pricedR & D Marine has developed a wide range of competitively priced FlexibleCouplings to fit all major R & D Flexible Couplings reduce engine noise, vibration transmission andare designed to accept propeller thrust, a separate thrust bearing and bulk headare not required.

2 The Couplings are made from a polyester elastomer which is not affected by saltwater, diesel and lubrication electrical continuity is required an earthing connector can be fitted in thecentre of most Flexible is quick and easy as the R & D coupling requires no machining andcomes supplied with bolts to connect between the two existing Shaft alignment on installation and during service checks is quick and easyusing the red cone headed are available ex-stock and worldwide through our distribution WorksClothall RoadBaldockHertfordshireEnglandSG7 6 PDContact Us By:Tel: +44 (0)1462 892391 Fax: +44 (0)1462 896448 Web Site: mail.

3 CONNECTORS R & D Marine Earthing Connector consists of a silver impregnated rubber strip, which when fitted through the axis of the couplingbetween the two fail safe straps gives electrical continuity. R & D have sizes to fit most 910 series PROCEDURE FOR R&D EARTHING carrying out the following procedure, ensure that the connector is not contaminated by grease or dirt. fitting the coupling into the drive train, remove 2 off bolts holding one of the fail safe straps. the fail safe strap to uncover the hole in the centre of the coupling .

4 Up the earthing connector (lengthways) as tight as possible. into the hole previously uncovered by removing the strapas far as possible. the fail safe strap ensuring that the connector is notdamaged, replace 2 off bolts. the coupling as per the installation electrical continuity on installation and thereafter at three to six month Suit Coupling910-021910-001, 002, 007, 013, 014, 019, 020, 028, 043910-004, 005910-003, 006, 009, 012, 036, 037, 044, 052910-017, 018, 025, 026910-029, 038, 039, 040, 057910-032, 033910-015, 016, 022, 024, 046, 048, 053910-030, 041, 042, 047, 051910-035, 045, 049.

Tightening details as alignment of engine by placing feeler gauges between the RED CONEHEADED BOLTand the rigid half coupling . Repeat for the SAME bolt at 90 intervals by rotating the the gap is the same in all four positions, the engine is accurately aligned. Recommended minimum to maximum gap difference: mm / Run installation to bring engine compartment to working temperature.
