How to repair and maintain the gearbox of wheel loader


Maintaining the gearbox of a wheel loader is essential to improve performance and efficiency. Periodically changing transmission fluids, cleaning filters, checking transmission components for wear and adjusting the transmission system can reduce energy loss and friction and ensure proper transmission operation. This not only improves the working efficiency of the loader, but also extends the service life of the gearbox, reduces maintenance costs and replacement costs, and ensures the reliability and durability of the loader. As a professional wheel loader manufacturer in China, OXPLO can give you the following suggestions.

1. Follow the manufacturer's recommendations: First of all, it is important to carefully read and follow the loader's manual and the manufacturer's repair and maintenance guidelines. These guidelines usually contain specific requirements and recommendations for gearboxes. Ensure operation and maintenance as recommended by the manufacturer.

2. Regular check of liquid level and quality: Regular check of liquid level and quality of transmission is the key to maintain its normal operation. Ensure that the transmission fluid is within the appropriate range and that the fluid quality meets the specified standards. If you want to add or replace liquids, be sure to use the specifications of the recommended model.

3. Pay attention to the gearbox temperature: too high or too low temperature will have a negative impact on the gearbox performance. Therefore, check regularly and ensure that the temperature of the gearbox is within the normal range. If too high a temperature is detected, the cause should be found and repaired in time.

4. Replace the filter regularly: The filter is essential to keep the inside of the gearbox clean and prevent contaminants from entering. Replace the filter regularly to ensure that it effectively filters impurities and maintains good working condition.

5.Check and adjust the belt: the tightness of the belt is crucial to the proper operation of the gearbox. Check the wear of the belt regularly and adjust or replace it as needed.

6. Check and maintain the transmission chain and gear: check the wear of the transmission chain and gear regularly, and carry out the necessary lubrication and maintenance. Make sure the chain is lubricated and the gear is working properly and repaired or replaced as needed.

7. Check the seals and pipes regularly: check the seals and pipes of the gearbox for leakage or wear. Any problems found should be repaired promptly to prevent fluid leakage and further damage.

8. Closely observe abnormal conditions: Regularly check the working condition of the gearbox, and closely observe whether there is abnormal noise, vibration or oil leakage and other problems. Any abnormal situation should be repaired in time to avoid further expansion of damage.

There are some additional tips and caveats

1. Pay attention to correct operation: Correct operation is the key to protect the gearbox. Avoid sudden gears, sharp acceleration or deceleration, and unnecessary shocks and excessive loads. These actions may cause damage to the internal parts of the gearbox.

2. Replace the lubricating oil regularly: the lubricating oil of the gearbox plays an important role in maintaining normal operation and reducing friction. Replace lubricating oil regularly according to manufacturer's recommendations to ensure proper operation. Select the appropriate lubricant brand and specification to ensure optimum performance and protection.

3. Pay attention to the maintenance and maintenance interval: according to the use of the loader and the working environment, develop a reasonable maintenance and maintenance interval. If the loader is operating under harsh conditions, such as dust or high temperatures, frequent maintenance may be required. Pay close attention to the manufacturer's suggestions and adjust them according to the actual situation.

4. Make records and logs: The establishment of maintenance and maintenance records and logs is an important way to track the condition of the loader gearbox. Record details such as dates, repair items, replacement parts, and lubricating oil changes. This helps track maintenance history, identify potential problems, and plan future maintenance efforts.

5. Preventive maintenance: In addition to regular maintenance, preventive maintenance is also important. By inspecting and testing critical parts and systems, potential signs of failure can be detected in advance and repaired or replaced. This helps avoid emergency repairs and increased downtime.

Regular maintenance and maintenance of wheel loaders' gearboxes can extend their service life, increase efficiency, and reduce the risk of breakdowns and downtime. Following the manufacturer's recommendations, properly planning maintenance plans, and recording maintenance details are all important steps to ensure that the gearbox is operating at its best.
