## 🔌 Function

Clamps the flywheel to the crankshaft flange, providing the bearing area and tensile strength the crankshaft-to-flywheel joint needs.

## ⚠️ Common Signs of Failure

-   Knocking or rumble from the flywheel end under load
-   Starter grinding or jumping out as alignment moves
-   Rust-coloured fretting dust around the flywheel flange
-   Screw found stretched or necked at the thread, or the head face found fretted
-   Flywheel and crankshaft flange found polished by relative movement

## 🛠️ Service Notes

-   Check the thread and length against the M16 x 1.5, 109 mm specification before fitting - flywheel joints use several screw lengths
-   Renew rather than reuse where the workshop procedure identifies the screw as torque-to-yield or single-use
