Worldwide availability

Competitively priced

R & D Marine has developed a wide range of competitively priced FlexibleCouplings to fit all major installations.

The R & D Flexible Couplings reduce engine noise, vibration transmission andare designed to accept propeller thrust, a separate thrust bearing and bulk headare not required.

The couplings are made from a polyester elastomer which is not affected by saltwater, diesel and lubrication fluids.

If electrical continuity is required an earthing connector can be fitted in thecentre of most Flexible Couplings.

Installation is quick and easy as the R & D Coupling requires no machining andcomes supplied with bolts to connect between the two existing shaft flanges.

Checking alignment on installation and during service checks is quick and easyusing the red cone headed bolt.

Products are available ex-stock and worldwide through our distribution network.

EARTHING 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 couplings.

INSTALLATION PROCEDURE FOR R&D EARTHING CONNECTORS

1. While carrying out the following procedure, ensure that the connector is not contaminated by grease or dirt. 2. Before fitting the coupling into the drive train, remove 2 off bolts holding one of the fail safe straps. 3. Remove the fail safe strap to uncover the hole in the centre of the coupling. 4. Roll up the earthing connector (lengthways)

as tight as possible.

5. Push into the hole previously uncovered by removing the strapas far as possible.

6. Replace the fail safe strap ensuring that the connector is notdamaged, replace 2 off bolts.

7. Fit the coupling as per the installation instructions.8. Check electrical continuity on installation and thereafter

at three to six month intervals.

INSTALLATION PROCEDURE FOR R & D MARINE COUPLINGS1. 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 rotating the shaft.

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 bring engine compartment to working temperature. Re-check torque settings.

Recommended tightening torque:M8 - 27 Nm 20 lbsft 3/8 UNF - 40 Nm 30 lbsft M10 - 61 Nm 45 lbsft 7/16 UNF - 81 Nm 60 lbsft M12 - 108 Nm 80 lbsft1/2 UNF - 100 Nm 75 lbsft 5/8 UNF - 210 Nm 155 lbsft M18 - 338 Nm 250 lbsft 3/4 UNF - 366 Nm 270 lbsft

(Pitch circle diameter is the distance between the centre of hole at 12 O`clock position to the centre of the hole at 6 o`clock)

The R & D 910 Series couplings consist of a contoured flexible disc moulded in tough yet resilient new type Polyester Elastomer. The contoured disc givesclearance for bolt heads, and is able to flex freely to take up any temporary misalignment of the engine and shaft, due to flexing of the boat structure or theengine moving on its rubber vibration isolation mountings. Forward thrust is taken in compression on the disc between the two half couplings and reverse thrustis taken again in compression on the disc between the two fail safe straps. In the unlikely event of a disc failure, the steel straps make the coupling fail safe andensure drive is maintained in both forward and reverse.

Couplings as standard are non-conducting but we can supply a silver impregnated rubber element to fit in the centre of the coupling between the twofail safe straps to give continuity if required.
