To ensure the quality and service life of automotive gears during maintenance, a series of measures need to be taken to protect the gears from wear, corrosion, and other damage. Here are some key suggestions:

1. Regularly replace gear oil:

Gear oil will lose its lubrication performance over time, and regular replacement of gear oil can ensure that gears always receive appropriate lubrication.

2. Check the quality of gear oil:

Regularly check the color and viscosity of gear oil, as well as whether there are foreign objects such as metal shavings, which can help determine the wear of gears.

3. Keep the gearbox clean:

Regularly inspect and clean the gearbox to remove dust, moisture, and impurities that may cause gear wear and corrosion.

4. Avoid overloading during use:

Avoid running the car under overload or extreme conditions to reduce excessive wear on the gears.

5. Check the gear clearance:

Regularly check the meshing clearance of the gears to ensure that the clearance is within the manufacturer's specified range. Excessive or insufficient clearance may affect the performance of the gears.

6. Use appropriate lubricants:

Choose lubricants that are suitable for the gear type and working conditions, ensuring they have appropriate viscosity, extreme pressure performance, and oxidation resistance.

7. Avoid moisture and corrosion:

Ensure good sealing of the gearbox to prevent moisture from entering, as moisture can cause lubricant emulsification and accelerate gear corrosion.

8. Regularly check the sealing of the gearbox:

Regularly check the sealing of the gearbox to ensure there are no leaks, as leaks can cause lubricant loss and increase gear wear.

9. Avoid sudden acceleration and braking:

Avoid sudden acceleration and braking, as these actions can generate impact loads and accelerate gear wear.

10. Professional maintenance:

When there is a problem with the gear, seek professional repair services to avoid further damage that may result from self repair.

11. Regular maintenance:

Regular professional maintenance, including cleaning, lubrication, and necessary adjustments of the gearbox.

12. Use high-quality gears:

Choose high-quality original or certified replacement gears to ensure the quality and performance of the gears.

Through the above measures, the quality and service life of automotive gears can be ensured during maintenance, thereby ensuring the normal operation of the transmission system and the performance of the vehicle.
