Failure Symptoms

The first sign of a damaged 12-tooth gear might be an audible clicking or grinding noise during operation, especially under load. If left unaddressed, the damage can progress to chipped or broken teeth, leading to increased vibration, power loss, and potential jamming of the drive system. Continued operation risks complete gear failure, which could cause significant damage to connected components and halt equipment operation.

Installation Tip

Ensure the gear mounting surface and shaft are perfectly clean and free from any burrs or debris. Avoid using excessive force or hammering to seat the gear, as this can damage the gear teeth or the shaft.

Service Note

When replacing this gear, inspect the mating gear and any associated bearings for wear or damage.
