1, high-pressure pipe wear oil leakage. Tractor tractor high-pressure fuel pipe at both ends of the nose and the injector, the oil valve leakage at the place of wear, can be cut from the waste cylinder mat round copper, a small hole in the middle grinding, slipping between the embossed pit Resolvable urgent need.
2, sudden shortage of oil supply. If there is insufficient fuel supply during the operation of the tractor, if the air is not replaced after the air is replaced by the plunger or the fuel injector, the small steel ball in the ejector pin of the injector may be worn so that the fuel injection cannot be atomized. At this point, a small steel ball should be changed.
3. Shake the steering wheel and swing the front wheel. Mainly due to improper positioning of the front wheels, due to the small amount of caster angle. In the absence of instrument detection, try to add a wedge-shaped iron piece at the rear end of the plane of the leaf spring and the front axle support so that the front axle can be turned back and then the caster angle can be increased. After the test run, it can return to normal.
4, free gearshift after shifting. The main reason is that the fork shaft groove wears, the fork spring weakens, and the gap between the connecting rod joints is too large. At this time, repair slot should be used, fork spring should be replaced, and the gap between connecting rods should be reduced. After shifting into position, normal speed can be ensured.
5, poor performance of oil pump. In order to solve the problem that the overhauled or overhauled locomotive can not start up the oil pump pump for the first time, the oil filter or the oil outlet pipe can be removed, then the oil filter can be used to fill the oil outlet hole with the oil, and the filter can be immediately replaced. Or the oil pipe leading to the oil indicator, after starting, the oil will be pumped up.
6, hydraulic hose fatigue breakage. Due to the frequent change of oil pressure and high oil temperature, the hydraulic oil pipe causes the pipe wall to be frequently opened, and is prone to fatigue damage. In order to effectively extend the service life of the hydraulic hose, it is best to use a thin wire burning spring to put it into the tubing for support.
7, hydraulic brake brake failure. It is necessary to carefully check the master cylinder and the branch cylinder, and whether or not the brake oil is replaced on time, completely eliminate the air in the brake line, and check whether the brake pedal meets the scientific height. The pneumatic braking locomotive must check to adjust the maximum brake working pressure and check whether the brake cup and hose have abnormal changes.
8, diesel engine oil burning blue smoke. In addition to checking whether the cylinder piston group is worn, whether the elasticity of the piston ring is weakened, whether the sump oil is added excessively, and whether the air cleaner oil level is too high, the problem remains unsolved. Check whether the clearance between the valve stem and the valve guide tube is checked. Too large this potential cause.
9. Scale causes excessive engine temperature. Many engine cooling pump scales can cause excessive engine temperatures, accelerated parts wear, lower power, and burn the oil of the lubricating pump. Two large dried loofahs can be picked to remove the skin and the seeds, cleaned and put into the water tank, and the scale can be removed after regular replacement.
10, inner tube slowly spread gas. The inner air should be exhausted as much as possible. Insert a valve into the funnel using cardboard as a funnel. Take two tablespoons of talcum powder and pour the inner tube into the inner tube. After the completion, the valve core is filled with air. Talcum powder diffuses and adheres to the sidewall after being dispersed in the fetus, which can effectively stop the tiny pores from spreading slowly.
