Fear of "dirty"
Fuel filter, oil filter, air filter, hydraulic oil filters and all kinds of spare parts such as filter if dirty, deterioration in filtration effect, excessive impurities into the oil cylinder, parts wear, and increase the likelihood of failure.If it is seriously blocked, the vehicle will not work properly.The radiator fin, air-cooled engine cylinder block and cylinder head heat sink, cooler heat sink and other parts dirty, can cause the heat dissipation, the temperature is too high.Therefore, for such "fear of dirty" parts must be cleaned and maintained in time.
2. Afraid of "strings"
All kinds of matching parts of diesel engine fuel system, master-slave motion within the drive axle of main reducer gear, hydraulic control valve and the valve stem, valve core and valve in the hydraulic steering gear set, etc., these together with the couple in the manufactured through special processing, grinding and become, in pairs with precise, in the use of the life of the period is always used in pairs, must not swap.Cooperate with each other, such as the piston and cylinder liner, bearing and shaft neck, valve and valve seat, big end tiles and shaft etc., after a period of running-in effect, relative to cooperate better, in maintenance, also should pay attention to assembly in pairs, don't "visit" to each other.
3. Fear of "lack"
In the maintenance of the vehicle, some of the small pieces may be neglected by omission, and some people think that it is dangerous and harmful to wear and do not care.The engine valve lock should be installed in pairs, such as leakage or missing, which will cause the valve to run out of control and smash the piston, etc.Engine connecting rod bolt, flywheel bolts, shaft bolt is installed on the split pin, lock screw, locking devices such as insurance or trampoline, once the packing, may lead to serious failure in use;When the engine timing gear room is used to lubricate the gear's oil nozzle, it will cause severe drainage and low pressure of engine oil.The water tank cover, oil cover, the oil cap loss, will make the sand, dust and other intrusion, aggravate the various parts wear.
