🔌 Function

Stores rotational energy to smooth the firing pulses, carries the ring gear the starter engages, and provides the drive face to the transmission.

⚠️ Common Signs of Failure

• Starter grinding or failing to engage cleanly, from damaged ring gear teeth
• Vibration or a rumble that changes with engine speed
• Scoring, heat cracking or bluing on the friction or drive face
• Speed or position signal lost or erratic, from a damaged sensor hole or target
• Bolt holes or dowels worn, letting the flywheel move on the crankshaft flange

🛠️ Service Notes

• The sensor hole and the serial breakpoint are the deciding details, so confirm the engine is from serial number 106090 onwards and takes the alfa sensor arrangement
• At 42.5 kg this needs lifting support and two people, and it must never be handled on the ring gear alone
• Use new flywheel bolts and tighten to specification, and check the rear crankshaft seal while access is clear
