Talk about the reason why the first gear of the loader is incapable of driving

Aug 07, 2022
Loaders are mainly used for shoveling, loading, unloading, earth moving and bulk materials such as stones, and can also perform light shoveling operations on hard soil. If you change different working devices, you can also complete the work of bulldozing, lifting, loading and unloading other materials. In highway construction, it is mainly used for filling and excavation of roadbed engineering, aggregate and loading of asphalt and cement concrete yard. Because it has the advantages of fast operation speed, good maneuverability, and easy operation, it has developed rapidly and has become the main machinery in earthwork construction. If the first gear of the loader is incapable of driving, the solution is to first check the pressure of the speedometer to see if there is a drop in pressure in the first gear. If the pressure is below 98.1KPa, the first gear drive will be powerless. The reason for these phenomena is that the piston ring of the first gear is scratched or worn too much, so that the pressure oil leaks too much, so that the driving of the first gear is powerless. In addition, it is also possible that the O-ring outside the first gear cylinder is damaged, causing a large amount of pressure oil leakage; if the fault is caused by the above reasons, the gearbox needs to be lifted out, and the damaged piston ring and sealing ring need to be disassembled and replaced. ; If there is no pressure drop on the gear shift pressure gauge in the first gear position, it is likely that the gear shift lever is not adjusted properly, which makes the first gear drive of the loader weak, and the gear shift lever should be readjusted to make it reach the specified position.
