- Position the designated component correctly before installing the lock nut.
- Start the nut by hand to prevent cross-threading.
- Tighten it using the correct wrench or socket.
- Follow the manufacturer’s specified torque value for the application.
- Avoid over-tightening, which may damage the nut, nylon insert, fastener, or secured component.
- Confirm that the assembly is secure before returning the generator to service.
Important: Nylon insert lock nuts may lose locking effectiveness after removal or repeated use. Replace the nut when required by the manufacturer’s service instructions. Always verify the equipment model, serial number, installation location, thread size, and original part number before ordering.
