What Causes the Grinding Noise When Starting in First Gear?

[StAndres]

The reasons for the grinding noise when starting in first gear are: 1. The clutch is not fully depressed; 2. The linkage mechanism is loose; 3. Severe wear of the clutch disc or damage to the pressure plate; 4. The gear is not fully engaged; 5. The release bearing lacks lubricant, causing dry friction or bearing damage; 6. Severe oil and dirt buildup between the release bearing sleeve and the guide tube, or fatigue, breakage, or detachment of the release bearing return spring and the pedal return spring, resulting in poor return of the release bearing. The solutions for gear engagement noise and abnormal sounds are: 1. Ensure the clutch is fully depressed; 2. Check the linkage mechanism and tighten it; 3. Replace the damaged clutch disc; 4. Master the correct gear engagement method and ensure the gear is fully engaged; 5. Tighten the loose gear lever (loose connecting rubber sleeve).
