While the HOWO from Sinotruk is one of the best commercial vehicle brands around the world, it is not the only option for global truck drivers. In terms of the maintenance of heavy-duty trucks, experienced drivers always keep fundamental and general principles in mind. We invite you to review the following bullet points to understand the general maintenance requirements for heavy trucks. It is also valuable to forward these points to your friends and colleagues in need.
Regular Inspection & Preventive Maintenance
- Conduct routine checks on the engine, transmission, brakes, suspension, and other critical systems.
- Look for wear, leaks, corrosion, or damage.
- Address minor issues early to avoid costly repairs and downtime.
- Follow a strict maintenance schedule to extend component lifespan and reduce operational costs.
Fluid Checks & Replacements
- Monitor and replace fluids as per manufacturer guidelines:
- Engine Oil: Prevents friction and overheating.
- Transmission Fluid: Ensures smooth gear shifts.
- Brake Fluid: Maintains braking efficiency.
- Coolant: Regulates engine temperature.
- Power Steering Fluid: Supports responsive handling.
- Use high-quality, truck-specific fluids for optimal performance.
Air Filter Maintenance
- Clean or replace air filters regularly.
- Promotes fuel efficiency and protects the engine from contaminants.
Greasing & Lubrication
- Lubricate moving parts like universal joints, kingpins, wheel bearings, and chassis fittings.
- Use appropriate grease types based on load, temperature, and environmental exposure.
- Apply systematically to reduce friction and wear.
Tire Care
- Check tire pressure and tread depth frequently.
- Rotate tires to ensure even wear.
- Replace tires showing signs of damage, wear, or ageing.
- Proper inflation improves fuel economy and safety.
Brake System Maintenance
- Inspect brake pads, rotors, callipers, and air brake components.
- Replace worn parts and adjust slack adjusters and brake shoe clearance.
- Ensure air compressors and lines are leak-free and functioning.
Electrical System Checks
- Inspect battery, alternator, wiring, and connectors.
- Clean terminals and ensure proper charging.
- Test lights and electrical components to meet safety standards.
