1. Fear of “dirty”
Parts such as fuel filters, oil filters, air filters, hydraulic oil filters and filters of various types, if dirty, can lead to poor filtering, excessive impurities entering the gas road cylinders, exacerbating the wear of the machinery and increasing the likelihood of failure; and, if seriously blocked, may also result in vehicles not working normally. Parts such as water tank radiators, wind-cooled engine cylinders and tank caps, and cooler radiators, etc., are too dirty, leading to dissipation and excessive temperatures. Therefore, such “dirty-resistant” parts must be kept clean in a timely manner。
2. Fear of "hot"
The high temperature of the engine piston, which can lead to overheated melting, overheat, overheated rubber seals, triangles, tyres, etc., are prone to premature aging, reduced performance and reduced service life; electrical equipment, such as starters, generators, regulators, etc., are overheated and easily burned to death; vehicle bearings should be kept at the appropriate temperature, such as overheating, which can lead to rapid deterioration of lubric oil, eventually leading to burning of the bearings and damage to the vehicle。
3. Fear of string
The various dolls in diesel fuel systems, the main owner of the main brakes driving the bridge, from gear gears, hydraulic-manufacturing valves and valves, the cores and valves in the whole hydraulic transformer, etc., are specially processed at the time of manufacture, sharpened into pairs, and are very sophisticated, and are used consistently throughout their useful life and are not interchangeable. A number of complementary elements, such as pistons and tatters, axles and necks, gas and gas doors, co-opts and head caps, etc., are relatively well coordinated over time, and should also be prepared in pairs and not “strengths” with each other during maintenance。
4. Fear of "anti"
Engine cask pads may not be retrofitted at the time they are installed, otherwise they may lead to premature burn-down damage; special shape piston rings may not be retrofitted and should be assembled according to different types of aircraft; engine fans there are directional requirements for the installation of blades, which are generally divided between wind and wind, which are not counterproductive because they otherwise cause engine heat dissipation and high temperature; for tyres with directional trajectories, such as human type trajectories, ground marks should be pointed to the back to ensure maximum driving power. For the two tyres that are packed together, different models also have different requirements and may not be installed at will。
5. Fear of “lack”
In the maintenance of vehicles, it is dangerous and harmful that small pieces may be inadvertently missing, even if some consider that they are irrelevant. Engine gas locks, which should be fitted in pairs, such as leaking or missing, which would cause the gas door to run out of control and break the piston; pineproof devices such as engine bolts, fly-wheel bolts, spin-off bolts, locking screws, insurance sheets or spring pads installed on engine bolts, which, if unloaded, could cause serious malfunctions; oil nozzles in the engine's gear room, which is used to lubricate the wheel, which, if leaked, would result in a severe spill of oil and low pressure on engine oil; loss of water, oil caps, oil tank caps, etc., would cause intrusion into sandstone, dust, and increase wear of all parts。
6. Fear of oil
The dry air filter paper filter core, which is more humid, e. G. Exposure to fluids, which can easily lead to higher concentrations of mixed gas inhalation cylinders, leads to insufficient air, increased fuel consumption and reduced engine power, and diesel engines may also cause “fly vehicles”; if the triangle is exposed to fluids, it accelerates the deterioration of its corrosion and is prone to slippages, leading to reduced transmission efficiency; the grinding of hoof blades, dry discs, brakes, etc., can threaten the safety of the vehicle if the oil is contaminated with fluids, which can cause slippages, bad work, etc.; and the oil staining of the engine and generator charcoal brushes, which may result in low power and low electrical pressure of the generator due to poor exposure. Tyre rubber is sensitive to corrosion of oil, and exposure to oil can make rubber soft or skinless, and short-term exposure can lead to unusual and even serious damage to tyres。
Seven, afraid of washing
Some of the first drivers or first repairers may assume that all spare parts need to be cleaned, a perception that is one-sided. For the paper air filter core of an engine, no oil can be washed when removing the dust on it, except by light taping with the hand or high-pressure air blowing through the inside of the filter core; for the leather parts, it is not appropriate to wash the oil with clean rags。
8. Fear of “pressure”
If the outside tyre is stored in long-term piles and does not flip in time, it is deformed by squeeze, which affects its useful life; air filters, paper filter cores of fuel filters, if squeezed, can produce larger deformations that are not reliable for filtering; and rubber oil seals, trig tape, pipelines, etc., cannot be squeezed, as otherwise they can be deformed and affect normal use。
Fear of near fire
Rubber products such as tyres, triangular tape, tanneries and rubber oil seals, if close to the source of the fire, are prone to deterioration or damage and, on the other hand, can cause fire accidents. In particular, some diesel cars, which are difficult to start during the winter season, and some drivers, who often heat with jet lamps, must prevent the burning of lines, oil roads, etc。
Fear of repetition
Some parts should have been used once, while individual drivers or repairers were reused for reasons of economy or for lack of knowledge of the “prohibit”, which made them highly vulnerable to accidents. In general, when parts such as engine bolts, nuts, imported diesel oiljets, fixed bolts, cylinders, sealed copper mattresses, hydraulic systems, various oil seals, seals and sales of important parts, openings, etc., are removed, new items must be replaced; for engine cylinder pads, although undamaged, it is preferable to replace new items, because old ones are less resilient, sealed, and perishable, need to be replaced for less than a long time, and it is time-consuming to replace them as much as possible
