The maintenance methods for trailer accessories mainly include the following aspects:
Tire maintenance: Tires are one of the most vulnerable parts of trailers. Check the wear of tire tread regularly to ensure that the tire pressure meets the specified standards. Check whether there are cracks or cracks on the tire surface. Once safety hazards are found, the tires should be replaced in time, and the selected tire models should be consistent.
Chassis maintenance: The chassis part includes suspension system, front axle/rear axle oil seals, front axle/rear axle bearings and other components. It is necessary to regularly check the looseness of the suspension system, replace worn parts, and check whether the chassis connection bolts are loose to ensure the stability and safety of the chassis.
Air brake system maintenance: The air brake system is the safety guarantee of the trailer. It is necessary to regularly check the working condition of the brake pump to ensure that the braking performance meets the requirements. At the same time, check whether there is oil leakage in the transmission system and repair it in time. Regularly replace the brake pads and adjust the clutch clearance to ensure braking capacity and driving safety.
Electrical system maintenance: The electrical system of the trailer includes the cabin lights, turn signals, etc. It is necessary to regularly check whether the electrical system connectors are loose or corroded, and the cable wear. If there is wear, it should be replaced in time, and the electrical system should be kept clean and dry to reduce the risk of short circuit.
Axle maintenance: Daily maintenance of the axle includes checking the tightness of the bolts and nuts of the wheels and suspension system to ensure that they reach the specified torque. Regularly check the thickness and looseness of the brake shoe friction pads and brake drums, and replace the worn parts in time. In addition, the inspection and maintenance of the hub bearing clearance is also very important to ensure the smooth and safe operation of the vehicle.
Battery maintenance: Check the fixation of the battery to ensure that it is firm and reliable. Keep the electrolyte level between the upper and lower limits. If it is close to the lower limit, add electrolyte or distilled water to the high level line in time. Keep the positive and negative cables of the battery in good contact, and keep the battery clean and dry.
Clutch master cylinder fluid level check: The normal clutch fluid level should be between the high and low levels. If the liquid level is lower than the standard line, it may mean that the master cylinder or slave cylinder cup is damaged and needs to be repaired in time.
