As the backbone of modern logistics and transportation, trucks operate under high-intensity conditions year-round. Scientific and standardized maintenance can not only significantly extend vehicle lifespan but also effectively ensure driving safety and optimize operational efficiency.
This article provides a detailed overview of the key maintenance points for truck core systems, helping you establish a scientific maintenance system.
1. Engine System Maintenance Guidelines
The engine is the core component of a truck and must be carefully maintained. During the break-in period for a new vehicle, strictly control speed and load. It is generally recommended to avoid excessive loads and high-speed driving within the first 10,000 kilometers to allow the engine to break in properly, resulting in smoother power output and better fuel economy.
Regularly check antifreeze and engine oil levels. Choose genuine engine oil from reputable brands that meet engine specifications. Also, refuel at reputable gas stations. Inferior diesel fuel can damage critical components such as the high-pressure fuel pump and fuel injectors, leading to high repair costs.
In addition, the diesel fuel filter, fuel-water separator, and air filter should be replaced regularly. The replacement cycle depends on fuel quality, mileage, and road conditions. Use genuine parts whenever possible to protect the engine.
2. In-depth Maintenance of the Braking System
The braking system is crucial for driving safety, and its routine maintenance cannot be neglected. Before driving, check the brake fluid level; if it is low, immediately check for leaks in the brake fluid lines. Brake fluid easily absorbs moisture from the air, so it is recommended to change it annually.
Heavy-duty trucks commonly use pneumatic braking systems. It is necessary to regularly drain water from the system and replace the dryer periodically to prevent moisture from corroding the lines, affecting braking performance, or even causing brake failure. Also, regularly check the air pump’s operation and the wear of the air pump belt, replacing it promptly.
In addition, regularly check the wear of the brake discs and brake pads; replace them immediately if excessively worn. Ensure that the brake lines are free of leaks, damage, and aging.
3. Scientific Management of the Tire System
Tires are the only part of a truck in contact with the ground, and their condition directly affects driving safety and transportation efficiency. Before each trip, check tire pressure. Both over-inflation and under-inflation are harmful. Adjust tire pressure appropriately according to different road conditions and weather; for example, lower the pressure on wet, hot roads and inflate the tires promptly when the temperature drops suddenly.
Carefully inspect tires for damage, such as cracks or rib breaks. Replace any damaged tires immediately. After the truck has traveled a certain mileage, rotate the front and rear tires to ensure even wear and extend tire life. Furthermore, tires older than 6 years should be replaced regardless of their appearance; perform tire rotation as required during secondary maintenance or after 10,000 kilometers.
4. Maintenance of Other Key Components
(1) Cooling System: Check coolant level and quality annually or every 20,000 kilometers to ensure proper radiator and fan operation and prevent engine overheating.
(2) Transmission System: Change transmission fluid every 40,000 kilometers, check drive shaft connections and lubrication to ensure smooth transmission.
(3) Lighting and Signaling System: Inspect all lights and signaling systems monthly, promptly repair or replace faulty parts to ensure driving safety.
(4) Suspension System: Inspect suspension components every 10,000 kilometers to ensure proper functioning and improve driving stability and comfort.
Truck maintenance is a systematic project that requires truck drivers to pay close attention and conduct frequent checks during daily use, strictly adhering to maintenance cycles and requirements.
Only in this way can trucks maintain good condition and complete transportation tasks efficiently and safely.
