How to Select (details required)1. Engine horse power and Engine Speed2. Gearbox type and reduction ratio3. Gearbox flange details. Diameter of flange. Diameter of register. Pitch circle diameter of fixing holes. Size and quantity of holes

(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)Example

1. Ford 150 HP at 2500 RPM2. Borg Warner Velvet Drive 72C 2:1 Reduction3. 5” Flange, 2.500 dia Register, 4.250 PCD, 4 off holes 0.437 diameter

To calculate Power of coupling required. Horse Power of Engine x Reduction Ratio x 100 = HP/100rpmEngine Speed

150 x 2 x 100 = 12 HP/100 rpm Coupling Required 910-009 Borg Warner2500

The R & D 910 Series couplings consist of a contoured flexible disc moulded in tough yet resilient new type Polyester Elastomer. The contoured discgives clearance 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 boatstructure or the engine moving on its rubber vibration isolation mountings. Forward thrust is taken in compression on the disc between the two halfcouplings and reverse thrust is taken again in compression on the disc between the two fail safe straps. In the unlikely event of a disc failure, the steelstraps make the coupling fail safe and ensure 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 betweenthe two fail safe straps to give continuity if required.

Couplings 910-030, 910-035, 910-041 and 910-045 will require suitable adaptors for the gearbox flange

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.

Flexible Engine Mountings

R & D Marine Engine Mountings

How to select (details required)1. Engine type, number of cylinders2. Type of gearbox and reduction ratio3. Weight of engine and gearbox combined by weighing or manufacturers literature4. Is flywheel in conventional place between the engine and gearbox5. Position of engine mounting points6. Find centre of gravity by balancing on a roller (if possible)

7. If Centre of Gravity cannot be found, assume weight distribution of 60% on rear mounts, with 40% on frontmounts. (if rear mount is in line with flywheel).

Installation DetailsMaximum clearance between the underside of the height adjusting nut and top washer must not be more than 10mm. If moreheight is required use a spacer under the mounting casting. This applies to all mountings in the R & D Marine Range.

Damper Drive Plates

• For engines up to 800 HP

• Torque range 60-1400 lb ft

• Reduces gear noise

• Allows engine to run at

lower speeds


• Machined ready to install

• Elements suitable for every

application

• Element has good heat

qualities

• Special back plates up to

533mm (21.0") diameter

• Element is impervious to

salt water, diesel and

lubrication oils



• No springs to rust or fret


R & D Marine has developed a wide range of competitively priced DamperDrive Plates to fit most engine/gearbox combinations.

The R & D Damper Drive Plates reduce gear noise and allow the engine to runat lower speeds.

Linear Stiffness elements for general applications and High-Deflection elementsto stop gear noise and spline wear at slow speeds.

All dampers are designed to be Fail-Safe and maintain the drive if the flexibleelement fails.

The flexible elements are made from a Polyester Elastomer which has good heatqualities and is not affected by salt water, diesel and lubrication oils.

Non-standard items are available for special installations, maximum back platediameter of 533mm (21.0").

Installation is made quick and easy as the R & D Damper Drive Plate requiresno machining and is ready to bolt to the flywheel.


Element SelectionConsider the following criteria when making a decision on the element design.

Loop type General purpose robust element which can be mounted either way round on the flywheel and can rotate in eitherdirection. Linear stiffness up to 3 degrees of deflection.

Hammer Head More torsionally flexible than the loop type, usually has smaller diameter element than our other designs butstill retains the ability to be mounted either way round on the flywheel and rotate in either direction. Three stage stiffnesswith up to 9 degrees of deflection.

High Deflection (H/D) Softer than our other designs with a maximum deflection up to 30 degrees, slightly larger diameterelement than other designs and can only be fitted to rotate in the standard direction of rotation (anti-clockwise looking at theflywheel). With the element facing the gearbox. Suitable for work boats with slow speed applications and pleasure boats.

Details required for Damper Selection1. Manufacturer of Engine, Engine Horse Power, Engine Speed, Number of cylinders2. Manufacturer of Gearbox, Model Number and Input Spline Details.3. Back plate diameter, Number of holes, Size of holes, Pitch circle diameter of holes.

Does the plate fit on the face of the flywheel or locate in a register?4. Will the element of the Drive Plate fit on the outside of the flywheel or be reversed and fit inside a flywheel recess?5. Type of application. Pleasure or Work Boat? Does it spend long periods at low engine speeds

• If an existing installation with a failed part •6. Type and Part Number of Damper that has failed7. What has failed. Spline or Element/Springs?

Damper Selection ProcedureExample 1) Ford 150 HP at 2500 RPM 6 Cylinder

2) Borg Warner Velvet Drive 72C Spline 26 teeth 20/40 DP 1.394 diameter3) Back Plate diameter 14.250, fixing holes 6 x 0.375 diameter on13.500 pcd spaced in 3 groupe of 2. No register4) Element fits on outside of flywheel5) Work Boat with a lot of slow speed work.

The R & D Damper comprises 3 main components, Spline plate, Element and Back plate, these 3 components are given a code which make upthe finished part number.. The following procedure will lead you through the selection process.

1. Select the correct power and style of element for the application .Use the manufacturers maximum torque figure for the engine or calculate from the known data of maximum horsepower rating at what rpm. Using the example installation above we get 315 lb ft or 427 Nm

To calculate output Torque of engine Horse Power of Engine x 5250 = Torque lbft 150 x 5250 = 315 lb ft Horse Power of Engine x 7123 = Torque Nm 150 x 7123 = 427 Nm

Engine Speed 2500 Engine Speed 2500From the Element selection chart we see the most suitable element has a code of AD and a fixing of 4 x 1/2 (8.00)

2. Select the correct Spline Plate to suit the Gearbox Input ShaftUsing the example, go to the Gearbox Details to find the Borg Warner 72 has a 26 Tooth 20/40 DP input spline. In the Selection Chartbelow look down the Element Fixing column find 4 x 1/2 (8.00) looking across find the 26T 20/40 DP input spline, in the next column isthe correct code of 48 for the spline plate. The furthest column to the right gives the list number of the Back Plates available for thisElement fixing, in this case List 7

3. Select the correct Back Plate to suit the FlywheelUsing the example, go to Back Plate List 7 on page 4. Looking down the list find the matching bolt pattern, in this case Back Plate 2
