🔌 Function

Clamps the flexible coupling to its mating flange, the integral flange under the head spreading the clamping load across the joint face.

⚠️ Common Signs of Failure

• Knocking or a vibration from the coupling that comes and goes with load
• Screws found slack, with fretting or bright rubbing marks on the joint face
• Elongated or bruised holes in the coupling flange
• Thread stretched, so it binds part way down
• Head corroded or the drive rounded

🛠️ Service Notes

• The flexible coupling sits in the drive line between the engine and the gearbox. A screw that works loose here can let the coupling break up, so renew the complete set rather than a single screw and tighten to the figure in the engine's manual
• Inspect the coupling element itself while the screws are out, as slack fasteners usually mean the element has already been working
