The maintenance method of common fault of tractor?

1, high pressure tubing wear oil leakage. The protruding head at both ends of the tractor high pressure tubing and the injector and the oil outlet valve are connected with the phenomenon of wear and oil leakage. A round copper skin can be cut from the exhaust gas cylinder pad, and a small hole is inserted in the middle to smooth it. The pad can solve the pressing problem between the protruding pit.

2. Sudden shortage of oil supply. There is insufficient oil supply in the operation of the tractor. If the exhaust air is not effective after replacing the plunger and nozzle, it is caused by the small steel ball partial grinding in the ejector needle rod so that the injection can not be atomized. At this time should be replaced by a small steel ball, if not available bicycle flywheel steel ball instead.

3, steering wheel shaking, front wheel swing head. The phenomenon of shaking the steering wheel and shaking the front wheel is mainly caused by improper positioning of the front wheel and too small inclination Angle of the kingpin. In the absence of instrument detection, try to plug wedge iron in the leaf spring and the rear end of the front axle bearing plane, so that the front axle turns after, and then increase the kingpin after inclination Angle, can be restored to normal after trial operation

4. Free shift after shifting. In the operation of the tractor, the phenomenon of free gear jumping after the speed change is mainly caused by the wear of the fork shaft slot, the weak fork spring and the large gap of the connecting rod joint. At this time, the positioning slot should be repaired, the fork spring should be replaced, the connecting rod joint gap should be reduced, and the normal speed change can be ensured after the gear is in place.

5. Poor performance of oil pump. In order to solve the problem that the oil pump does not come up after overhauling or overhauling the locomotive for the first time after starting the engine, the oil filter or outlet pipe should be removed, and then the oil injector is filled with oil from the oil outlet hole of the body, and the filter or the oil pipe leading to the oil indicator is immediately better. After starting, the oil will be pumped up.

6, hydraulic tubing fatigue damage. Hydraulic tubing due to frequent changes in oil pressure and high oil temperature, resulting in frequent wall tension, fatigue damage is easy to lead to accidents. In order to prolong the service life of hydraulic tubing effectively, the spring is put into the tubing as support.

7, hydraulic braking locomotive braking failure. To carefully check the brake pump and sub-pump, whether to replace the brake oil on time, exclude the brake pipeline air, and to check whether the brake pedal is in line with the scientific height. Pneumatic braking locomotive to check the adjustment of the larger brake working pressure, check whether abnormal changes occur in the brake bowl and hose.

Diesel engine oil smoke blue. Diesel engine oil smoke blue, in addition to check whether the cylinder liner piston group wear, piston ring elasticity is weakened, oil sump oil is added too much, air filter oil level is too high after the problem has not been solved, should pay attention to check whether the valve rod and valve guide with clearance is too large this potential cause.

9. Excessive engine temperature is caused by scale. The scale of the engine cooling pump will lead to too high engine temperature, accelerate the wear of parts, reduce power, and burn the oil of the lubricating pump. Scientific soil method is: choose two big loofah, remove skin and seed, after cleaning, put into cistern, regular change can divide scale. Tank water should not often change, change frequently will increase the formation of scale.

10, the inner tube is slow. The rubber inner tube should be slowly ventilated. The air in the inner tube should be put out as far as possible. Insert the valve nozzle with a funnel made of hard paper and take two tablespoons of talcum powder into the inner tube. Talc powder dispersed in the fetus was diffuse adhesion on the wall, can effectively prevent small pores slowly air, the effect is very good.

The above are just some emergency measures, to solve the problem but also to repair the garage seriously.
