The flywheel ring — also known as a ring gear — is a toothed metal ring mounted around the outer edge of the engine flywheel. Its teeth engage with the starter motor's drive gear each time the engine is cranked, transferring the rotational force needed to turn the engine over and initiate combustion. On heavy-use compaction equipment like the RD7H series rollers, the ring teeth are subjected to repeated high-load engagement and can wear or chip over time. When the ring is worn, the starter motor fails to catch cleanly, leading to slow cranking, grinding, or a complete no-start condition that takes the machine out of service.
