Suggestions For Maintenance Of Basic Vehicles After Delivery Of Export Heavy-duty Trucks

After the delivery and operation of the new export heavy-duty truck, the early running in and basic maintenance directly determine the vehicle's later failure rate, fuel economy, and overall service life. Many overseas fleets directly carry out high-intensity heavy load operations on new cars, ignoring the maintenance standards during the new car running in period, resulting in accelerated engine wear, premature aging of parts, increased chassis clearance, and continuous small vehicle failures in the later stages. Proper basic maintenance after the delivery of a new car is the key to reducing maintenance costs and maintaining vehicle stability in the long run. It is suitable for reference and execution by all cross-border long-distance and heavy-duty construction teams. Pay attention to standardized operation during the running in period of new cars and eliminate violent driving. During the break in period of a new heavy-duty truck, if the engine, gearbox, and chassis transmission components are not fully engaged, it is strictly prohibited to drive at full load for a long time, exceed the speed limit, start suddenly, or brake abruptly. It is recommended to control the load reasonably for the first two thousand kilometers, drive at a constant speed, and avoid low-speed and high load towing operations. A gentle and standardized driving style can allow the power components to fully break in, effectively improving the vehicle's sealing and transmission efficiency, laying the foundation for long-term stable operation in the later stage. Complete the first maintenance on time and lock in the best performance of the entire vehicle. The first maintenance is the core node of new car maintenance. During the running in period, a large amount of metal debris and impurities will be generated in the engine oil. If not replaced in time, it will exacerbate the internal wear of the engine. Overseas fleets must strictly follow the manufacturer's standards to complete the first maintenance on time, replace the engine oil, oil filter, and fuel filter element, and comprehensively inspect the condition of the transmission oil and rear axle gear oil. After the first maintenance is completed, tighten the chassis screws of the entire vehicle, check the sealing of the pipelines, and eliminate the hidden dangers of assembly gaps in the new car. Carry out regular inspections of oil, water, and gas pipelines. At the beginning of new car delivery, it is necessary to develop the habit of checking the oil and water daily, regularly checking the coolant, engine oil, and brake oil levels to avoid problems such as high temperature and wear caused by running low on fluid. In response to complex environments such as frequent dust, rain, and low temperatures overseas, it is important to inspect the working status of the air path dryer, promptly drain the accumulated water in the air storage cylinder, prevent pipeline icing and valve body jamming, and ensure the sensitivity and stability of the braking system. Regularly check the status of the chassis and suspension system. After initial long-distance driving and bumps and vibrations, the chassis fasteners of the new car are prone to slight looseness. Daily maintenance should focus on rechecking key parts such as steel plate springs, saddle bolts, thrust rods, shock absorbers, tire screws, etc., and promptly tightening loose points. At the same time, check the tire pressure and wear condition to ensure that the air pressure on all four wheels is balanced, avoid running and uneven wear problems, and improve driving stability. Establish a dedicated maintenance ledger for new cars and plan maintenance cycles in advance. The wear and tear pattern of new car operating conditions is more stable, and the fleet can establish independent maintenance records to record the first maintenance time, consumables replacement cycle, and operating mileage. Flexibly adjust maintenance intervals based on local road conditions, oil products, and climate, predict component wear in advance, and achieve preventive maintenance. In summary, the initial maintenance of export heavy-duty trucks after delivery is crucial. Scientific running in, timely first maintenance, regular inspections, and refined management can effectively avoid early failures of new cars, optimize vehicle performance, extend vehicle service life, help overseas fleets reduce long-term maintenance costs, and continuously improve transportation attendance efficiency and operational revenue.
