1. Air Conditioning:
The air conditioning system of a semi-truck is essential for the comfort and safety of the driver during long hauls. Regular maintenance and inspection should be performed to make sure that the system is in proper working order. The primary components to check are the refrigerant levels, drive belts, hoses, and compressor.
Inspecting the belts of a semi-truck is an important part of regular maintenance. Belts should be inspected regularly for cracks, wear, and fraying. Replace any worn or damaged belts immediately to prevent costly repairs in the future.
3. Braking System:
The braking system of a semi-truck is critical for safety on the roads. Inspect brake pads, the master cylinder, disc rotors, and calipers at least once a year or more often if necessary. Check for leaks and make sure that all components are properly adjusted for optimal performance.
4. Cooling System:
Check coolant levels as well as hoses and other components of the cooling system. If there is any visible leakage, replace the hoses immediately. Make sure that all connections are secure and tight to ensure efficient engine performance.
5. Drive Shafts or CV Joints:
Check drive shafts or CV joints for wear and tear as well as proper alignment. Any misalignment can cause major damage to the truck down the line, so it’s important to inspect them regularly.
Inspect electrical systems for corrosion, loose connections, interior lights, exterior lights, and fuses. Corrosion should be removed with an appropriate cleaner or solvent to prevent further damage from occurring. Tighten any loose connections and check that all lights are working properly.
7. Engine Mounts:
Make sure that all engine mounts are in the correct position and secure to prevent excessive vibrations from occurring. If any of the mounts are loose, replace them immediately to ensure proper operation of the truck.
8. Exhaust System:
Check for cracks or leaks in the exhaust system and repair any issues immediately. The exhaust system should also be checked for blockages due to debris such as leaves or twigs which can diminish performance.
Fluid levels should always be monitored and checked regularly for leakage, clogs, contamination, or other problems. The fluids that need attention include fuel, antifreeze/coolant, engine oil, power steering fluid, brake fluid, and transmission fluid.
Fuses are an important part of any electrical system and should be inspected regularly for damage or corrosion. If there is any visible wear or damage to the fuse box, replace it immediately to prevent further damage from occurring.
Inspect seat belts for proper operation as well as the structure of the seat itself for cracks or tears in the material. Replace any damaged or worn seat belts or seats right away to ensure a safe ride for both driver and passengers.
Check all components of the steering system such as tie rods, ball joints, drag links, etc., for wear, corrosion, and other issues. Make sure all components are in the correct position and secure to prevent any dangerous situations while on the road.
Check tire pressure regularly as well as tread depth for proper operation. Tires should also be inspected for cracks or bulges which can indicate a puncture that needs to be fixed immediately to ensure safety on the roads.
14. Transmission Mounts:
Transmission mounts should always be checked for proper alignment and position as well as wear or damage that may cause vibration or engine noise during operation. Replace any worn parts right away to prevent further damage from occurring.
Inspect wheels for rust, dents, or any other damage that may cause the wheel to become unbalanced. Also check the lug nuts for proper torque and make sure they are tight to prevent the wheel from becoming loose while on the road.
