How to maintain auto parts (I)

If the fuel filter, oil filter, air filter, hydraulic oil filter and various filters and other parts are too dirty, it will lead to poor filtration effect, too many impurities will enter the oil cylinder, aggravate the wear of the parts, increase the possibility of failure, and if it is seriously blocked, it will also lead to the vehicle can not work normally. Parts such as the radiator of the water tank, the air-cooled engine block and cylinder head radiator, and the cooler radiator are too dirty, which will lead to poor heat dissipation and excessive temperature. Therefore, for such "dirty" parts, it is necessary to clean and maintain them in time.
1. Afraid of "dirty".
If the fuel filter, oil filter, air filter, hydraulic oil filter and various filters and other parts are too dirty, it will lead to poor filtration effect, too many impurities will enter the oil cylinder, aggravate the wear of the parts, increase the possibility of failure, and if it is seriously blocked, it will also lead to the vehicle can not work normally. Parts such as the radiator of the water tank, the air-cooled engine block and cylinder head radiator, and the cooler radiator are too dirty, which will lead to poor heat dissipation and excessive temperature. Therefore, for such "dirty" parts, it is necessary to clean and maintain them in time.
2. Fear of "heat".
The engine piston temperature is too high, which can easily lead to overheating and melting: rubber seals, triangle tapes, tires, etc. are overheated, which is easy to premature aging, performance degradation, and shortening service life, and the coils of electrical equipment such as starters, generators, and regulators are overheated, which are easy to burn and scrap; Vehicle bearings should be kept at the appropriate temperature, if overheated, the lubricating oil will deteriorate quickly, eventually leading to bearing burnout and vehicle damage.
3. Afraid of "strings".
Various couplings in the diesel engine fuel system, the main and slave gears in the drive axle main reducer, the hydraulic control valve block and valve stem, the valve core and valve sleeve in the full hydraulic steering gear, etc., these coupling parts are specially processed and ground in pairs during manufacturing, and the matching is very precise, and they are always used in pairs during the life of use, and must not be interchanged. Some inter-matched parts, such as piston and cylinder liner, bearing and journal, valve and valve seat, connecting rod head tile cover and shaft, etc., after a period of running-in, relatively good fit, in the maintenance, should also pay attention to the pair assembly, do not "cross the door" with each other.
4. Fear of "anti".
The engine cylinder gasket can not be installed in reverse, otherwise it will lead to premature ablation damage to the cylinder gasket: the piston ring of some special shapes can not be reversed, and it should be assembled according to the requirements of different models: the engine fan blades also have direction requirements when installed, and the fan is generally divided into exhaust and suction, which can not be reversed, otherwise it will lead to poor engine heat dissipation and high temperature for tires with directional patterns, such as herringbone tires, the ground imprint after installation should make the herringbone tip point to the rear to ensure that it has a large driving force. For the two tires installed together, different models also have different requirements, and they cannot be installed at will.
5. Fear of "shortage".
When repairing the vehicle, some small parts may be missed due to negligence, and even some people think that it doesn't matter whether they are installed or not, which is very dangerous and harmful. Engine valve locks should be installed in pairs, such as missing or missing will lead to valve loss of control and damage to the piston and other parts: engine connecting rod bolts, flywheel bolts, drive shaft bolts installed on the clincher pin, locking screws, fuses or spring pads and other anti-loosening devices, once missing, in use will likely lead to serious failures: once the oil nozzle used to lubricate the gear in the engine timing gear chamber is missing, it will lead to serious oil leakage there, so that the engine oil pressure is too low: water tank cover, oil port cap, fuel tank cover is lost, It will intrude into sand, dust, etc., and aggravate the wear of various parts.
