Troubleshooting Symptoms of a Cracked Gear

A failing gear often shows early signs such as clicking noises, hesitation under load, or the locomotive stopping while the motor continues to spin. These symptoms indicate the original gear has split and can no longer grip the axle properly. Installing a fresh replacement gear restores full torque transfer and prevents additional wear on the motor and drive block.
