The hydraulic transmission system used on the Komatsu PC200-5 excavator mainly includes the pilot control hydraulic system,

reverse hydraulic system, walking hydraulic system, and operating equipment hydraulic system. It has advantages such as compact layout,

sensitive action, smooth operation, and convenient operation.

The hydraulic system uses hydraulic oil as the medium for power transmission, which may leak due to internal component wear and tear,

accompanied by overheating, and Komatsu accessories being unable to operate. The presentation of hydraulic transmission problems is sudden and covert, and involves many components,

which brings certain difficulties to the diagnosis and cleaning of problems.

Therefore, when repairing hydraulic systems, it is necessary to understand their operating principles and correctly analyze the causes of problems in order to ensure the quality of repair
