Truck maintenance is generally divided into one guarantee, two guarantees and three guarantees.
First, the vehicle level maintenance inspection items
(1) Replace the oil, oil filter, gasoline filter and air filter.
(2) Check whether the liquid level position of automobile coolant meets the requirements.
(3) Check the liquid level position of the brake and clutch.
(4) Check whether the oil level of the power steering oil tank meets the requirements, and check whether there is oil leakage at each oil pipe interface of the system.
(5) Check the liquid level of the battery and the glass cleaning tank.
(6) Check the tightness and aging of belts of generators, air conditioners, water pumps and booster pumps.
(7) Check whether the front and rear lights of the car are complete (including headlights, width indicators, turn signals, brake lights, reversing lights and fog lights).
(8) Check the tire pressure and wear condition of the automobile, tighten the tire screws according to the specified torque, supplement the tire pressure to the specified value of the vehicle model, and carry out tire transposition according to the wear condition.
(9) Check whether the automobile exhaust emission is up to standard.
Second, the vehicle secondary maintenance inspection items
(1) After the engine passes the operation of three cleanings and three filters, it should be easy to start, run smoothly, exhaust normally (referring to the exhaust standard), the water temperature and oil pressure meet the requirements, the speed is stable, there is no abnormal sound, the belt is moderately tight, and there are no four leaks (water, oil, electricity and gas).
(2) The free travel and toe-in in the direction meet the requirements, the steering is light, flexible and reliable, and the front wheel has no left-right swing and deviation when driving.
(3) The free stroke of the clutch meets the requirements, with convenient operation, complete separation, stable and reliable combination, no abnormal sound and no oil leakage in the hydraulic system.
(4) Gearbox, drive axle, universal joint (or half shaft) transmission device, etc. Good lubrication, reliable connection, no abnormal sound and overheating, no tripping, flexible gear shifting and no oil leakage.
(5) The free travel of the brake pedal and the braking interval meet the requirements, the driving and parking braking are good, there is no deviation and delay during braking, the inertia proportional valve works normally and there is no oil leakage.
(6) The tire pressure is normal (different models have different high and low air pressure standards).
(7) The cantilever and the shock absorber are fixed reliably and function normally, and the temperature of the hub bearing is not too high after driving.
(8) The generator, starter, lights, instruments, signal lights, buttons and switches are complete and can work normally.
(9) Add lubricating oil to all lubricating points of the whole vehicle.
(10) Wash and clean the whole vehicle.
Third, the vehicle three-level maintenance inspection items
Three-level maintenance centers on assembly disassembly, cleaning, inspection and adjustment.
