1. High-pressure tubing wear and leakage If there is oil leakage and leakage between the nose and the fuel injector and the oil valve at both ends of the tractor's high-pressure fuel pipe, you can cut 1 round copper skin from the waste cylinder pad with a small hole in the middle. Smooth, cushioning between the embossed pits can be urgent.
2. Inadequate bursts of fuel supply during tractor operation. If the air is not removed, the plunger is replaced, or the nozzle is not effective, the small steel ball in the injector pin is eccentrically worn. As a result, the spray cannot be atomized. At this time, one small steel ball should be changed, or replaced by a bicycle flywheel steel ball.
3. The steering wheel shook, the front wheel swinged and the front wheel wobbled, and the front wheel shook his head. The main reason was that the front wheel was improperly positioned and the main pin was too small. In the absence of instrument detection, try to add a wedge-shaped iron piece to 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 trial run, it can return to normal.
4. After the automatic gear shifting, the automatic skipping phenomenon occurs after shifting, which is mainly caused by the wear of the fork shaft groove, weakening of the fork spring, and the excessive clearance of the connecting rod joint. In this case, the repair slot should be used to replace the fork spring and reduce the gap of the connecting rod joint. After the gear is in place, normal speed can be ensured.
5. The poor performance of the oil pump solves the problem of poor performance of the oil pump after overhaul or overhaul, the problem that the locomotive cannot start up when the engine is started for the first time, the oil filter or the oil outlet pipe can be removed, and then the oil hole is filled with the oil from the oil outlet hole by the oiler. Immediately after the filter or the oil line leading to the oil indicator is turned on, the oil will be pumped up.
6. Hydraulic tubing fatigue fracture Hydraulic oil tubing frequently changes in oil pressure and the oil temperature is high, resulting in frequent wall relaxation and easy fatigue failure. To effectively extend the service life of the hydraulic hose, it is best to use a thin wire to form a spring and put it into the tubing for support.
7. Hydraulic Brake Locomotive Brake Check carefully Check the master cylinder and the slave pump to see if the brake oil has been replaced on time and thoroughly remove the air from the brake line and check that the brake pedal is of a scientific height.
8. The diesel engine burns blue smoke to check whether the piston sleeve of the cylinder sleeve is worn, whether the elasticity of the piston ring is weakened, whether the sump oil is added excessively, and whether the air cleaner oil surface is too high or not. If blue smoke is still left after the solution, Care should be taken to check for potential causes of excessive fit clearance between the valve stem and the valve guide tube.
9. Excessive Engine Temperature Caused by Scales Excessive scale on the engine cooling pump can cause the engine to overheat, which can accelerate the wear of parts, reduce power, and burn the oil that lubricates the pump. The exclusion method is: pick two large loofah, remove the skin and the seeds, clean and put it into the water tank, and periodically remove it to remove scale. The water in the water tank should not be changed frequently. Changing the ground will increase the formation of scale.
