This key sits in a machined keyway in the crankshaft and prevents the mounted components from spinning freely on the shaft. Proper key engagement is critical for maintaining correct ignition timing and clutch drive alignment.\u003c\/p\u003e\n\u003cp\u003eA sheared or worn shaft key will cause ignition timing to shift unpredictably, resulting in poor performance, detonation risk, or a no-start condition. Always inspect the key and keyway during bottom-end service.
