How to maintain auto parts

Many car owners in the purchase of accessories very carefully and carefully, but after installation is easy to forget the maintenance of accessories, so that in the case of the car journey gradually increased, accessories are very easy to wear and tear, the use of time in the continuous shortening. The following provides you with ten accessories maintenance precautions, only car owners reference.

1, afraid of "dirty"

Fuel filters, oil filters, air filters, hydraulic oil filters and various types of filters and other parts if dirty, will lead to poor filtering effect, too many impurities into the oil cylinder, exacerbate the wear and tear of the parts, increasing the likelihood of failure; if the serious clogging, it will also lead to the vehicle can not work properly. Water tank heat sink, air-cooled engine block and cylinder head heat sink, cooler heat sink and other parts are too dirty, will lead to poor heat dissipation, the temperature is too high. Therefore, for this kind of "afraid of dirty" parts must be cleaned and maintained in a timely manner.

2, afraid of "hot"

Engine piston temperature is too high, easy to cause overheating melting and hold cylinder; rubber seals, triangular tape, tires and other overheating, easy to premature aging, performance degradation, shorten the service life; starter, generator, regulator and other electrical equipment, coil overheating, very easy to burn and scrap; vehicle bearings should be kept at the appropriate temperature, such as overheating, will make the lubricating oil deteriorate very quickly, and ultimately lead to bearing burnt out, the vehicle is damaged.

3, afraid of "string"

Diesel fuel system in a variety of coupling, drive axle main reducer within the master-slave gears, hydraulic manipulation valve block and valve stem, fully hydraulic steering valve core and valve sleeve, etc., these with the coupling in the manufacture of special processing, grinding into pairs, with very precise, in the use of the life of the use of the pairs of always use, do not interchangeable. Some of the mating parts, such as the piston and cylinder liner, axial tile and journal, valve and valve seat, connecting rod big head tile cover and rod body, after a period of time, the role of friction, relatively good with the maintenance, should pay attention to the pair assembly, do not "string door" each other.

4, afraid of "anti"

Engine cylinder gasket in the installation can not be installed in reverse, otherwise it will lead to premature damage to the cylinder gasket erosion; some special shapes of the piston ring can not be installed in reverse, should be assembled according to the requirements of different models; engine fan blade installation also has the direction of the requirements of the fan is generally divided into two kinds of exhaust and suction, can not be made in reverse, otherwise it will lead to poor engine heat dissipation, high temperatures; on the direction of the pattern of the tire, such as herringbone pattern For tires with directional patterns, such as herringbone pattern, the ground marks after installation should make the herringbone tip point to the rear to ensure maximum driving force. For the parallel mounted two tires, different models also have different requirements, can not be installed at random.

5, afraid of "missing"

In the maintenance of vehicles, some small parts may be negligent and missed, and even some people think that it does not matter what is installed and not installed, which is very dangerous and harmful. Engine valve locking piece, should be installed in pairs, such as leakage or missing will lead to the valve out of control and hit the piston and other pieces; engine connecting rod bolts, flywheel bolts, drive shaft bolts installed on the cotter pins, locking screws, insurance pieces or spring pads and other anti-loosening devices, once the leakage, in the use of the serious failures will likely lead to; engine timing gear room used to lubricate the gears of the oil nozzles once the leakage, will lead to The serious oil leakage, so that the engine oil pressure is too low; water tank cover, oil port cover, fuel tank cover is lost, will make gravel, dust and other invasive, exacerbate the wear and tear of various parts of the machine.

6, afraid of "oil"

Engine dry air filter paper filter, hygroscopicity is strong, such as stained with oil, easy to make the concentration of higher mixture inhaled into the cylinder, so that the air volume is insufficient, increased fuel consumption, engine power decline, diesel engines may also cause "flying car"; if the triangle tape stained with oil, will accelerate its corrosion and aging, and at the same time prone to slipping, leading to Transmission efficiency is reduced; dry clutch ` friction plate, etc., if stained with oil, easy to slip, poor work, thus threatening the safety of driving; starter motor and generator carbon brush, etc., stained with oil is due to poor contact and lead to starter motor power, generator voltage is too low. Tire rubber corrosion of oil is very sensitive, and oil contact will make the rubber soften or peeling, short-term contact will lead to abnormal damage or even serious damage to the tire.

7, afraid of "wash"

Some of the first drive or learn to repair the personnel, may think that all spare parts need to be cleaned, in fact, this understanding is one-sided. For the engine's paper air filter, in removing the dust on it, you can not use any oil cleaning, just gently patted or high pressure air from inside the filter element to the outside can be blown through; for leather parts, should not be cleaned with oil, just use a clean rag to wipe clean.

8, afraid of "pressure"

Tire tires if long-term storage and not timely turn, will be deformed due to extrusion, affecting the service life; air filter, fuel filter paper filter, such as extrusion, will produce a large deformation and can not be reliably play a role in filtration; rubber oil seals, triangular tape, tubes, etc. can not be extruded, otherwise the same will be deformed, affecting the normal use.

9, afraid of "near fire".

Tires, triangular tape, cylinder blocking ring, rubber oil seals and other rubber products, if close to the fire, it will be easy to aging or damage, on the other hand, may also cause fire accidents. Especially some diesel cars, winter cold difficult to start, some drivers commonly used blowtorch heating, be sure to prevent burned lines, oil circuit.

10, afraid of "repeat"

Some parts should be a one-time use, individual drivers or repairmen but in order to save or because they do not understand the "taboo" and repeated use, which is very likely to lead to accidents. Generally speaking, the engine connecting rod bolts, nuts, imported diesel injectors fixed bolts, cylinder liner water blocking ring, sealing copper gasket, all kinds of hydraulic system oil seals, seals, and important parts of the pin, cotter pin and other parts of the dismantled, must be replaced with a new product; for the engine cylinder cushion, overhaul, although no damage was found, and it is best to replace the new product, because of the old product elasticity is poor, poor sealing, easy to erode and damage, the use of Not long to be replaced, time-consuming and laborious, so if there is a new product to try to replace the best.
