Troubleshooting Tips

Liugong motor grader is a common large-scale construction machinery, which can quickly complete operations such as excavation and land leveling on a large area of ground, and one of the most common failures is that the gear does not go away. So what exactly caused it?

First of all, the reason why the gear does not move may be caused by a problem with the gearbox. If the motor grader does not go in gear, it may be caused by the belt of the gearbox being loose, so that the gearbox will lose its connection. At this time, if the tightness of the belt is readjusted, this problem can be solved. In addition, this problem is also related to factors such as the slippage of the gearbox gear and the fall off of the synchronizer. If this happens, the gearbox will need to be overhauled and some transmission parts replaced.

Secondly, the failure of the motor grader to shift gears may also be caused by clutch failure. The clutch is a device used to connect or separate the engine and transmission. If it fails, the power of the engine cannot be transmitted to the transmission. There may be many reasons for clutch failure, such as severe wear of the clutch plate, improper adjustment of the clutch, too much or too little clutch oil, and so on. To solve this kind of failure, it is necessary to consider the problem from the perspective of the clutch, and repair or replace it.

In addition, the circuit problem is also a main reason why the motor grader does not go in gear. The electronic control system is the soul of the motor grader, and the faults that cannot be shifted in gear are generally caused by problems with the wiring. For example, sometimes the power supply of the circuit is insufficient due to aging or damage of the wire, which causes the motor grader to fail to start. Sometimes, due to the failure of the sensor, there will be problems with the electronic control system, which will cause the phenomenon that the gear will not go. This situation can be solved by checking and repairing the circuit.

Finally, there is another situation that may be caused by the driver’s own improper operation. The driver of the grader needs to be familiar with the use of the machine, and non-professional drivers can easily cause similar problems when they are in a hurry. Before using the motor grader, the driver needs to understand the structure of the machine in detail and master the skills of stably operating the motor grader. In addition, when there is a problem with the shifting of the gear, do not slam on the accelerator and brake, but relax appropriately, check the speedometer and other indicators, and if there is an emergency prompt, the driver needs to take countermeasures in time.

In short, there are many reasons why the motor grader does not go out of gear. When the driver finds the problem, he should first check the above problems one by one to find out the crux of the problem, and then make corresponding repairs in a targeted manner. Only by truly understanding the root cause of the motor grader’s failure can the problem of not moving when it is in gear be better avoided.
