🔌 Function

Secures the flywheel or flexible plate to the crankshaft flange, maintaining the clamp load that keeps the joint concentric and free of fretting.

⚠️ Common Signs of Failure

• Vibration or rumble from the flywheel end that changes with load
• Starter grinding or jumping out of engagement
• Rust-coloured fretting dust at the flywheel joint
• Screw found stretched or necked, or the head face found fretted
• Flange faces found polished where the joint has been moving

🛠️ Service Notes

• Follow the specified sequence and torque-angle procedure - a flywheel joint that is unevenly clamped frets and then fails
• Clean and check the flange faces before fitting; debris or a raised burr will lose the clamp load however well the screws are tightened
