The temperature of the engine piston is too high, which may cause overheating and melting to cause cylinder holding; rubber seals, triangle tapes, tires, etc. are overheated, which is prone to premature aging, reduced performance, and shortened service life; electrical appliances such as starters, generators, regulators The coil is overheated and easily burned and scrapped.
The engine cylinder gasket cannot be reversed during installation, otherwise the cylinder gasket will be prematurely ablated and damaged; the engine fan blades must not be reversed during installation; for tires with directional patterns and herringbone pattern tires, the ground impression after installation should be The chevron points to the back.
If the fuel filter, oil filter, air filter, hydraulic oil filter and various filters are too dirty, the filtering effect will be worse. Water tank fins, air-cooled engine block and cylinder head fins, cooler fins and other parts are too dirty, which will cause poor heat dissipation and high temperature.
Engine valve lock plates should be installed in pairs, such as missing or missing will cause the valve to run out of control and damage the piston, etc .; engine connecting rod bolts, flywheel bolts, split pins installed on drive shaft bolts, locking screws, safety plates or If the anti-loosening device such as spring pads is not installed, it may lead to serious failure in use; if the oil nozzle used to lubricate the gears in the engine timing gear room is leaked, it will cause serious oil leakage there.
For the paper air filter element of the engine, it can not be cleaned with any oil; for leather parts, it is not suitable to be cleaned with oil.
If the paper filter element of the engine dry air filter is stained with oil, it is easy for the denser mixed gas to be sucked into the cylinder, so that the amount of air is insufficient, the fuel consumption is increased, and the engine power is reduced. Corrosion and aging will be accelerated; oil on brake shoes, friction plates of dry clutches, and brake belts will threaten driving safety. Tire rubber is very sensitive to oil corrosion. Contact with oil will make the rubber soft or peeling.
If tire tyres are stored for a long time under stacking and are not flipped in time, they will be deformed due to squeezing; if the paper filter elements of air filters and fuel filters are squeezed, they cannot reliably perform the filtering function; Rubber oil seals, triangle tapes, tubing, etc. cannot be squeezed.
Some parts are supposed to be used once, but individual drivers or repairmen use them repeatedly for the sake of economy or because they do not understand the "taboo", which can easily lead to accidents.
Tires, triangle tapes, cylinder liners, rubber seals, and other rubber products, if they are close to the fire source, will easily deteriorate, deteriorate or be damaged. On the other hand, it may cause fire accidents.
