Among all construction machinery, excavators are one of the most common types of construction machinery. Excavators are being seen everywhere, and in excavators, Komatsu excavators are undoubtedly very popular. There are more people to use, and it is inevitable that there will be malfunctions. When the hydraulic system has problems, what is the procedure for the maintenance of Komatsu excavator hydraulic final drives?
Komatsu excavator hydraulic final drives repair
As we all know, the hydraulic final drives of Komatsu excavator is divided into structure, mainly gear final drives, vane final drives, etc. The gear final drives is taken as an example to introduce the fault and its diagnosis. The most common faults in gear final drive motors are wear on the final drives body and gears, cracks in the final drives body and mechanical damage. In general, the parts must be overhauled or replaced.
In our previous experience, the common faults of gear final drivess are: severe noise and pressure fluctuations; insufficient oil delivery: the hydraulic travel motors is abnormal or has a seizure phenomenon. When our Komatsu excavator has the above situation, we should promptly turn off the machine for a full inspection. When the above situation occurs, we should focus on the following areas:
First: the filter of the final drives: the filter of the final drives is blocked by dirt and cannot function as a filter.
Second: axial clearance and radial clearance: If the gap between the two is too large, it will lead to insufficient oil delivery.
Third: final drives body part: check the final drives body for cracks and pore leakage

Fourth: Oil inspection: Check whether the oil temperature is too high or the oil viscosity is too high. This phenomenon is also easy to cause the hydraulic final drives to lose oil.
Fifth: Oil level: To see if there is a situation where the oil level is too low and the oil supply is insufficient.
Sixth: Coupling: Check the concentricity of the coupling between the motor and the motor. Is there a situation where the concentricity is insufficient?
In general, Komatsu excavator hydraulic final drives repair can be detected through the above steps. When there is a problem with the machine, it should be followed by regular methods. Don't be anxious, be good at finding problems in the hydraulic final drives. If there is a situation that cannot be solved by yourself, you should contact the hydraulic final drives repair company to have the professional hydraulic final drives maintenance personnel come to repair the hydraulic final drives of Komatsu excavator.
