During the use of the tanker , regular maintenance should be performed to eliminate potential safety hazards, improve the performance of the tanker, extend its service life, and ensure safety.
First, the 2000km tanker maintenance is mainly based on fastening and lubrication.
1. When driving the tank truck every 2000km, inspect and tighten the connecting bolts and nuts of the engine mount, intake and exhaust manifold, and muffler, and check if each gasket is intact.
2. Check and tighten the connecting bolts of the drive shafts, cross shafts, intermediate supports, and steering mechanisms (especially the vertical and horizontal tie rods, steering upper and lower booms, steering transmission shafts, etc.), leaf springs, axles, and wheels.
3. Clean and maintain oil filters and diesel filters.
4, check the fan belt tension.
5, check the tire pressure, according to the provisions of inflation.
6. Check and fasten the connecting bolts and nuts on the cab and the car box.
7. Observe the operation of the supercharger. If there is any noise or vibration, it should be eliminated in time.
8, check the turbocharger bearings for oil leakage, such as oil spill is ruled out.
9. Check if the intercooler and the pipeline seal are good.
10. Check the dust in the air cleaner housing.
11, according to the lubrication table for lubrication.
2. Maintenance of 8000km of tank trucks (execution of 2000km maintenance projects plus addition of the following items) Mainly based on inspection and adjustment.
1. Replace the engine oil of the tanker and flush the oil pan.
2. Check and add the lubricant of the differential between the transmission, middle and rear axles of the tank truck and the middle axle, and clear the ventilation plug.
3. Adjust and lubricate the front and rear hubs and wheel brakes.
4. Adjust the gap between brake shoe friction plate and brake drum.
5, check the tanker parking brake work.
6. Check the steering wheel of the tanker for free rotation.
7, replace the power steering fluid.
8, check the tanker tires, transposition in accordance with the provisions of the order.
9, check and adjust the front wheel toe.
10. Clean fuel tank, oil pump inlet fittings and piping.
11. Clean the oil filter rotor, remove the deposit on the inner wall of the rotor cover, and clear the nozzle.
12. Clean the air filter element.
13, adjust the valve clearance.
14, radiator and intercooler in good condition.
15. Clean the diesel primary filter element; replace the diesel fine filter and the oil filter element.
16, focus on the inspection of safety components (such as the brake system of the rod, pipelines, steering system vertical and horizontal tie rods, steering knuckle arms, steering arm and the connection parts, etc.).
Check the shock absorber and find that it has been replaced in time.
Check bushings such as leaf spring brackets and rings for replacement.
Lubrication according to lubrication table
3. Maintenance of 24000km of tank trucks (Execution of 8000km maintenance projects and addition of the following items)
1. Check and replace the brake friction plates every time the tanker travels 24,000 km.
2. Remove the rear axle drive shaft and tighten the bevel gear flange nut and the intermediate drive shaft flange nut according to the specified torque.
3. Remove the rear cover of the middle and rear axle housings, clean the inner space of the reducer, tighten the differential bearing cap nut and the differential case nut according to the specified torque, and replace the middle and rear drive axle lubricants.
4, replace the transmission lubricant.
5. Check the wear condition of the leaf spring bracket and the eyebolt sleeve, and replace as appropriate.
6, replace the air filter filter.
7, according to the lubrication table for lubrication.
4. Maintenance of 48000km of tank trucks (Execution of 24,000km maintenance project and addition of the following items)
Disintegrate the assembly to eliminate hidden dangers.
For every 48,000km of tanker trucks, crankcase ventilation shall be cleaned.
Clean the cooling system and fuel tank.
Clean the oil cooler.
Professionals check the injection pressure and fuel injection of the injector on the test bench and make necessary adjustments.
Check the fuel advance and make necessary adjustments.
Adjust the oil pump as needed.
Remove the cylinder head as required, clean and inspect the parts, and grind the valve.
Except for the first 48,000km treatment according to the situation, every 48,000km will need to be tested, adjusted and maintained every 48,000km to eliminate hidden dangers.
The disintegration of the tanker engine should be determined according to its own working conditions. Where the work performance is good, it should not disintegrate or extend the disintegration cycle properly to maintain the original technical performance.
The fuel injection pump generally does not need to be adjusted. If the engine is not working properly, it should be checked and adjusted by a professional on the injection pump test bench.
Demolition of parking and service brake controls and piping. Clean the air reservoir check valve, check the brake valve, and adjust as appropriate.
Check the air compressor as appropriate.
The clutch, transmission, transmission shaft, mid-axle, rear axle, front axle and steering system are dismantled as required.
Replace the power steering oil and the filter element in the steering oil tank.
Examine the spare wheel lifter, replace worn parts, clean and lubricate.
The rims are rusted and painted.
Check the integrity of the tank frame (with or without deformation, cracks, loose rivets, etc.) and repair if necessary.
Repair and maintain body and accessories, replace damaged parts.
Check and adjust the battery electrolytic density.
Maintain the starter and generator, check the bearings.
Lubricate by tanker lubrication table.
This is to ensure that your car tanker is safe and sound.
