🔌 Function

Locates and drives its mating component from the shaft, transmitting the drive through a positive fit rather than by friction alone.

⚠️ Common Signs of Failure

• Knocking, rattle or backlash from the drive under load or on a throttle change
• Hub bore or keyway found worn, bruised or spread on strip-down
• Fretting corrosion or bright wear on the shaft where the hub sits
• Hub loose on its shaft, or a fastener repeatedly working slack
• Timing or drive position that will not stay where it was set

🛠️ Service Notes

• Inspect the shaft, key and mating component at the same time — a worn hub will have marked whatever it drives
• Clean the taper or bore dry before assembly and tighten the retaining fastener to your engine's figure
