## 🔌 Function

Stores rotational energy to smooth crankshaft speed, supports starter engagement through the ring gear and transfers engine torque into the transmission coupling.

## ⚠️ Common Signs of Failure

-   Starter grinding or failure to engage from damaged ring-gear teeth
-   Drivetrain vibration caused by run-out or imbalance
-   Cracking around the crankshaft or transmission mounting holes
-   Abnormal noise during starting or shutdown
-   Loose fasteners, fretting or damaged mounting faces

## 🛠️ Service Notes

-   Inspect the ring gear teeth for chipping, burring and one-sided wear before refitting — a damaged tooth ring will chew up a new starter pinion
-   Check the clutch or damper mating face for scoring, heat cracking and blueing, and check the crankshaft rear seal and any spigot bearing while access is good
-   Clean the crankshaft flange and the flywheel face so both are dry and free of oil, old sealant and burrs; a trace of oil on that joint is enough to let the flywheel work loose
-   Locate the flywheel the correct way round on its dowel or locating feature, and renew the bolts wherever the manual calls them single-use
-   Tighten the bolts progressively in a criss-cross pattern to the figure and stages given in the workshop manual for your engine, and never lever against the ring gear teeth to hold it
