🔌 Function

Smooths engine output by storing rotational energy between firing strokes, carries the starter ring gear, and presents the drive face to the transmission.

⚠️ Common Signs of Failure

• Grinding or whirring on cranking, with the starter failing to engage cleanly
• Chipped, hooked or missing ring gear teeth over one worn arc
• Judder or vibration as drive is taken up
• Heat cracking, blueing or scoring across the friction face
• Run-out or a wallowed bolt hole found when the flywheel is off

🛠️ Service Notes

• Check the starter pinion and its engagement for matching damage, since a worn pinion will chew a new ring gear
• Flywheel bolts are often single use and tightened to a set torque and sequence, so check the manual before reusing them
• Inspect the rear main seal and the spigot bearing while access is open
