🔌 Function
Retains the pulley on the alternator shaft, clamping it hard enough that belt drive torque is carried through the shaft taper or key rather than through the nut itself.
⚠️ Common Signs of Failure
- Charge warning light or a falling battery voltage under load
- Belt squeal, or a pulley seen wobbling or running out of line
- Nut found loose, with the pulley able to move on the shaft
- Fretting or bright rub marks between the pulley bore and the shaft
- Damaged shaft thread or a rounded nut recovered on removal
🛠️ Service Notes
- Confirm thread, length, grade and any single-use restriction against the exact application
- Clean the threads and use the specified torque, angle and locking method
