Komatsu excavator final drive motors repair

        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 Komatsu excavator travel motors maintenance?

         As we all know, the final drive motors of Komatsu excavator is divided into structure, mainly gear pump, vane pump, etc. The gear pump is taken as an example to introduce the fault and its diagnosis. The most common faults in gear pumps are wear on the pump body and gears, cracks in the pump body and mechanical damage. In general, the parts must be overhauled or replaced.

         In our previous experience, the common faults of gear pumps are: severe noise and pressure fluctuations; insufficient oil delivery: abnormal walking motor or seizure. 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 pump: the filter of the pump 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: pump body part: check the pump 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 pump 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 final drives maintenance 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 travel motor. If there is a situation that cannot be solved by yourself, you should contact the travel motor repair company to let the professional travel motor repairman come to the Komatsu excavator travel motor maintenance work.
