Many car owners are careful when buying auto parts, but it's easy to forget about the maintenance of parts after installation. In this way, in the case of gradually increasing car travel, parts are very easy to wear and tear, and the use time is constantly shortened. Then, let's learn about the maintenance methods of auto parts together!

1. Auto parts are afraid of getting dirty

If the fuel filter, oil filter, air filter, hydraulic oil filter, various filters and other components are too dirty, the filtering effect will be poor, and too much foreign matter will enter the oil circuit cylinder, causing the components to wear and fail. is more likely. Vehicles may also not function properly if there is a severe traffic jam. If the radiator fins, air-cooled engine block and head fins, cooler fins and other components are too dirty, the heat dissipation will deteriorate and the temperature will be too high. Therefore, clean and maintain such "dirty" parts immediately.

2. Auto parts are not heat resistant

If the temperature of the engine piston is too high, the overheating is easy to cause the cylinder; the rubber seals, V-belts, tires, etc. are overheated, which are prone to early aging, performance degradation, and shortened life; the coils of the starter, generator, regulator, etc. The bearings of scrapped vehicles need to be kept at a proper temperature. Once overheated, the lubricating oil will quickly deteriorate, and eventually the bearings will burn out and the vehicle will be damaged.

3. Auto parts are afraid of strings

Various couplings of diesel engine series, main and slave gears in the main reducer of the drive axle, hydraulically operated valve blocks and valve stems, valve bodies and sleeves of full hydraulic steering, etc. These couplings are specially machined at the time of manufacture, ground in pairs, are very precise, are used in pairs throughout their service life, and must never be replaced. Some intermeshing components, such as pistons and cylinder liners, bearing bushes and journals, valves and valve seats, connecting rod cylinder covers and shafts, mesh relatively well over time. During maintenance, care should also be taken to assemble in pairs to avoid "closeness" to each other.

4. Fear of resistance

When installing the engine pad, do not install it in reverse. Failure to do so will result in early ablation damage. For some special shapes of piston rings, they cannot be installed in reverse. Please assemble according to the requirements of different models; the installation of fan blades also has direction requirements. Fans generally have two types of exhaust and suction, do not do the opposite. On the contrary, the engine heat dissipation becomes poor and the temperature is too high. For tires with a directional pattern similar to herringbone tires, in order to ensure greater driving force, the ground traces after installation must be such that the front end of the herringbone faces the rear. Regarding the two tires installed side by side, the requirements vary according to the type of vehicle, so they cannot be installed casually.

5. Fear of insufficiency

When repairing the vehicle, some small items may have been accidentally installed. In addition, some people think that it does not matter whether it is installed or not. This is very dangerous and harmful. The door latches of the engine must be installed in pairs. For example, sometimes the valve is out of control due to missing or missing installation, collided with the piston, etc. and damaged; Cotter pins, locking screws, bumpers or spring washers installed on engine connecting rod bolts, flywheel bolts, drive shaft bolts, etc. If the loose device has installation leakage, it may cause serious failure in use. If the oil nozzle for lubricating the gears of the engine timing gear chamber leaks, the oil leakage from there will become severe and the pressure of the engine oil will become low. If the box cover, oil cover, oil cover is lost, gravel, dust, etc. will invade, aggravating the wear of various parts.

6. I am afraid of oil

The paper filter element of the dry filter has strong hygroscopicity. Once oil is attached to it, the high-concentration mixture is easily sucked into the cylinder, resulting in insufficient air volume, worsening fuel consumption rate, lower engine output, and possibly diesel engine. "Flying car". If the oil adheres to the V-belt, it will promote corrosion and deterioration, and at the same time, it will be easy to slip, and the transmission efficiency will decrease. If oil is attached to the brake pads, friction pads of dry clutches, brake bands, etc., it is prone to slippage or poor operation, threatening driving safety; if the carbon brushes of the starter motor and generator are attached with oil, poor contact will lead to starting The motor power is insufficient and the voltage of the generator drops. The rubber of the tire is very sensitive to the corrosion of oil. When it comes into contact with the oil, the rubber will become soft and peeling. Short-term contact will cause abnormal damage to the tire and serious damage.

7. Fear of repetition

Some parts are supposed to be disposable, but if individual drivers or mechanic reuse them for the sake of economy or not knowing "no taboos", accidents can easily occur. Generally speaking, after removing the engine connecting rod bolts, nuts, imported diesel injector fixing bolts, the water retaining ring of the cylinder liner, the sealing copper gasket, various oil seals of the hydraulic system, the sealing ring and the important parts of the pins, openings Regarding the engine cylinder gasket after the pin and other components, no damage was found during inspection, but it was replaced with a new one. The old one has poor elasticity, poor sealing, and is easy to age. It also needs to be replaced after long-term use, which is very troublesome, so if there is a new one, it is better to replace it as much as possible.

8. Not resistant to pressure

The outer tire of the tire should be stacked and stored for a long time. If it is not turned over in time, it will be deformed due to extrusion and affect its life. The paper filter elements of the air filter and fuel filter will be greatly deformed when stamped. The filter cannot be reliably played; the oil seal, V-belt, air pipe, etc. cannot be pressed. After pressing, it will also deform, affecting normal use.

9. Fear of fire

Auto parts include tires, triangular tapes, cylinder liner water retaining rings, rubber oil seals and other rubber products. If they are close to an open flame, they are prone to aging, deterioration and damage. On the other hand, they may also cause fire accidents. Especially some diesel cars are difficult to start because of the cold winter. Some drivers must often use the burner to heat, so as not to burn the lines, oil lines, etc.

10. I am afraid of doing laundry

Auto parts Some people who start driving or start repairing may think that all parts need to be cleaned, but in fact this understanding is one-sided. For the paper air filter of the engine, when removing the dust from it, do not wash it with any oil. Simply tap with your hand, or blow high-pressure air out of the filter. For leather parts, do not use oil to clean, just wipe with a clean rag.
