1. The steering wheel vibrates.
It is usually the four wheels of the tractor that have positioning problems. If there is a problem with the front wheel, it is usually the reason why the caster angle is relatively small, and try to increase the caster angle. A wedge-shaped iron plate can be inserted between the flat end of the front axle support and the spring steel plate, which can increase the caster angle and solve the problem of steering wheel vibration.
2. The oil pump of the oil pump fails to come up.
After a high-horsepower tractor has been repaired and maintained for a period of time, the performance of the oil pump may deteriorate, resulting in the phenomenon that the oil does not come up. This problem can be solved by replacing the oil filter or the oil outlet pipe of the oil. If it still does not work, you can try to inject oil from the oil outlet to solve the problem.
3. Fatigue damage of hydraulic oil pipe.
The hydraulic oil pipe may be fatigued and damaged in the repeated use of the machine, which is closely related to the frequent changes of oil pressure and the high oil temperature. Therefore, more consideration should be given to these factors when selecting the material of the hydraulic oil pipe. Some materials with better temperature and pressure resistance can solve such problems.
4. Hydraulic brake locomotive brake failure failure.
After a period of use, the machine sometimes has the phenomenon of locomotive brake failure. First, find out the cause of the failure, judge what the problem is, summarize the experience of these problems, and find out the areas where problems often occur to improve and solve them. question.
5. Free skipping failure after shifting.
The tractor inevitably needs to change speed during the working process, and the phenomenon of gear shift often occurs in the process of shifting gears, which is caused by the positioning problem of the fork spring or the increase of the gap of the connecting head. These problems can be solved by replacing the fork spring, repositioning and adjusting the clearance of the connector
