Using Komatsu WA500-3H Torqueflow (Pump And Drain Piping) Parts
Use the Komatsu WA500-3H Torqueflow (Pump And Drain Piping) Parts listing to identify aftermarket replacement parts within the torque converter and transmission section. This wheel loader application is listed for machine serial H20051 - UP; the diagram and parts table retain the selected configuration and its source notes.
The parts table contains 13 listed part occurrences, including pump assembly (reference 704-30-36110), adapter (reference 421-62-13760) and plug (reference 205-970-2860). Read any option and reference notes beside these entries before choosing a replacement; repeated references may represent separate positions in the source list.
When selecting transmission or torque-converter parts, compare the assembly description, machine serial break and any configuration notes. Similar-looking diagrams can cover different internal parts and should not be treated as interchangeable.
