Using Komatsu WA500-3 Wheel Loader Transmission (Parking Brake) Parts
Use the Komatsu WA500-3 Wheel Loader Transmission (Parking Brake) Parts listing to identify aftermarket replacement parts within the torque converter and transmission section. This wheel loader application is listed for machine serial 50001-UP; the diagram and parts table retain the selected configuration and its source notes.
The parts table contains 38 listed part occurrences, including transmission ass'y (reference 425-15-21003), transmission ass'y (reference 425-15-21002) and transmission ass'y (reference 425-15-21001). 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.
Catalog quantities describe the illustrated assembly. Adjust the order quantity to what you need, select the relevant rows, and use Add selected to cart for verified store matches or Add selected to quote for quote items. The diagram alone does not establish current stock or part interchangeability.
