Many car owners are very careful when buying auto parts, but it is easy to forget the maintenance of parts after installation. In this way, with the gradual increase of car travel, the parts are very easy to wear and the service time is continuously shortened. Let's learn about the complete collection of maintenance methods of auto parts!
1. Auto parts are afraid of being dirty
If the fuel filter, oil filter, air filter, hydraulic oil filter, various filters and other components are too dirty, the filtering effect will become worse, and too many foreign matters will enter the oil circuit cylinder, resulting in component wear and higher possibility of failure. If there is a serious traffic jam, the vehicle may not work properly. If the radiator fins, air-cooled engine block and head fins, cooler fins and other components are too dirty, the heat dissipation will become worse and the temperature will be too high. Therefore, clean and maintain such "dirty" parts immediately.
2. Heat resistance of auto parts
The engine piston temperature is too high and overheating is easy to produce barrel holding; Rubber seals, V-belts, tires, etc. are overheated, prone to early aging, reduced performance and shortened service life; The coils of starter, generator, regulator and other electrical appliances are overheated and easy to burn. The bearings of scrapped vehicles need to be kept at an appropriate temperature. Once overheated, the lubricating oil will deteriorate quickly, and finally the bearings will be burned and the vehicles will be damaged.
3. Auto parts fear string
Various couplings of diesel engine system, master-slave gears in the main reducer of drive axle, hydraulically operated valve block and valve rod, valve body and sleeve of full hydraulic steering, etc. These couplings are specially processed and ground in pairs during manufacture. They are very precise. They have been used in pairs throughout their service life and must not be replaced. Piston and cylinder liner, bearing bush and journal, valve and valve seat, connecting rod cylinder head, bearing cap and shaft and other meshing components mesh relatively well with the passage of time. During maintenance, attention should also be paid to assembly in pairs to avoid "approaching" each other.
4. Fear resistance
When installing the engine pad, do not install it in the opposite direction. Otherwise, it will cause early ablation damage. For some piston rings with special shapes, they cannot be installed in reverse. Please assemble according to the requirements of different models; The installation of fan blades also has direction requirements. Generally, there are two kinds of fans: exhaust and suction. Please do not do the opposite. Otherwise, the heat dissipation of the engine becomes worse and the temperature is too high. For tires with directional patterns similar to herringbone tires, in order to ensure large driving force, the ground trace after installation must make the front end of the herringbone face the rear. The two tires arranged in parallel have different requirements according to different vehicle types, so they cannot be installed casually.
5. Fear deficiency
When repairing the vehicle, some small objects may accidentally Miss installation. In addition, some people think that it doesn't matter whether it is installed or not. This is very dangerous and harmful. The door locks of the engine must be installed in pairs. For example, sometimes the valve is out of control and damaged by collision with the piston due to missing or missing installation; If there is leakage in the installation of locking devices such as cotter pins, locking screws, bumpers or spring pads installed on engine connecting rod bolts, flywheel bolts and transmission shaft bolts, serious faults may be caused in use. If the oil nozzle used to lubricate the gears in the engine timing gear chamber leaks, the oil leakage from there will become serious and the pressure of the engine oil will become low. If the box cover, oil cover and oil cover are lost, gravel and dust will invade and aggravate the wear of various parts.
6. Oil is afraid of me
The paper filter element of the dry filter has strong moisture absorption. Once the oil is attached, the mixture with high concentration is easy to be sucked into the cylinder, resulting in insufficient air volume, deterioration of fuel consumption rate, decline of engine output power, and possibly "flying" of diesel engine. If the oil is attached to the triangular tape, it will promote corrosion deterioration, slip easily and reduce the transmission efficiency. If the brake pad, friction plate of dry clutch and brake belt are attached with oil, it is easy to slip or act poorly, threatening driving safety; If the carbon brushes of the starting motor and generator are attached with oil, poor contact will lead to insufficient power of the starting motor and voltage drop of the generator. The rubber of the tire is very sensitive to the corrosion of oil. When contacting with oil, the rubber will become soft and peeling. Short time contact will lead to abnormal and serious damage to the tire.
7. Fear of repetition
Some parts should be disposable, but if individual drivers or repairmen reuse them in order to save or do not know the "taboo", it is easy to cause accidents. Generally speaking, after removing the engine connecting rod bolts, nuts, fixing bolts of imported diesel engine fuel injector, water retaining ring of cylinder liner, sealing copper gasket, various oil seals, sealing rings of hydraulic system, pins and split pins of important parts, the engine cylinder gasket is not damaged during inspection, but it is replaced with a new one. The old ones have poor elasticity, poor sealing and easy aging. They also need to be replaced after long-term use, which is very troublesome. Therefore, if there is a new one, it is better to replace it as much as possible.
8. Non compression
The outer tube of the tire shall be stacked and kept for a long time. If it is not turned over in time, it will be deformed due to extrusion and affect the service life; The paper filter elements of air filter and fuel filter will deform greatly when stamping, so they can not play the role of filter reliably; Oil seal, triangular tape, air pipe, etc. shall not be pressed. After pressing, it will also deform and affect normal use.
9. Fear of fire
Auto parts include tires, triangular tape, cylinder liner water retaining ring, rubber oil seal and other rubber products. If they are close to open fire, they are easy to aging, deterioration and damage. On the other hand, they may also cause fire accidents. In particular, some diesel vehicles are difficult to start because of the cold winter. Some drivers must often heat with burners to avoid burning lines, oil circuits, etc.
10. I'm afraid of washing clothes
Some people who start driving or repairing auto parts 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, do not use any oil to clean the dust on it. Just tap gently with your hand or blow out high-pressure air from the inside and outside of the filter. For leather parts, there is no need to clean them with oil, just wipe them with a clean rag.
