R&D Marine 4" Split Clamp On Coupling for 25mm Shaft, Volvo Penta

 

Part No: 808454

 

This clamp on split half coupling is machined from solid steel and mates with the gearbox output coupling to connect a 25mm metric diameter boat propeller shaft to a Volvo Penta gearbox, usually via a flexible coupling.

The clamp on split type propeller shaft coupling is machined to suit the boat propeller shaft diameter but can accommodate the variations that can occur with normal boat propeller shaft tolerances. It is simple to install and can be adjusted to the required position on the shaft. This clamp on shaft coupling is bored only (no keyway) and is secured to the boat propeller shaft with the clamp bolts supplied.

Typical applications include:

4" nominal gearbox flanges of Volvo Penta MS & RB gearboxes.

Recommended torque for the clamp bolts: 54Nm (40 lbsft)

Coupling dimensions:

For propeller shaft diameter 25mm (bored only, no key way)

a - Flange outside diameter = 4.00"

b - Hole pitch circle = 80mm

c - Number of holes = 4

d - Hole size = 10mm

e - Register diameter = 60mm female

f - Coupling length = 3.28"

g - Coupling clamp boss diameter = 3.38"
