🔌 Function

Smooths crankshaft speed fluctuations, provides starter engagement and transmits engine torque to the generator or driven equipment.

⚠️ Common Signs of Failure

• Cracked or heat-checked friction/coupling face
• Loose flywheel fasteners
• Fretting at crankshaft mounting face

🛠️ 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
