Tractor maintenance points

1. The steering wheel is shaken, and the front wheel swinging head fails and the steering wheel shakes and shakes the front wheel. The main reason is that the front wheel is improperly positioned and the kingpin is 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.

2. Faults with poor performance of oil pump To solve the problem that the overhaul or overhauled locomotive is not able to start the oil pump pump for the first time, the oil filter or the outlet pipe should be removed, and then the oil filter should be used to fill the oil hole from the machine body. Oil, immediately on the filter or the oil indicator to the oil indicator, start, the oil will be pumped up.

3, hydraulic tubing fatigue fracture failure Hydraulic tubing due to frequent changes in oil pressure and high oil temperature, resulting in frequent pipe wall relaxation, prone to fatigue damage caused by the accident. 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.

4, hydraulic brake brake failure failure to seriously check the brake master cylinder and the sub-pump, whether to replace the brake oil on time, to completely eliminate the air brake circuit, and to see 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.

5. The diesel engine burns blue smoke and the diesel engine burns blue smoke. In addition to checking whether the cylinder piston group wears, whether the piston ring elasticity is weakened, whether the oil sump oil is added excessively, or if the air filter oil level is too high, If the problem still remains unsolved, attention should be paid to checking whether the gap between the valve stem and the valve guide is too large as a potential cause.

6, free gear shift after the speed change tractor operation, after the shift there is a free jump phenomenon, mainly fork shaft slot wear, fork spring weakened, connecting rod joint part of the gap caused by too much. At this point, the repair slot should be used to replace the fork spring, reduce the gap between the connecting rod joints, and ensure the normal speed change after the files are in place.
