Using Komatsu WA380-3 Transmission (Forward And Reverse Clutch) Parts
Use the Komatsu WA380-3 Transmission (Forward And Reverse Clutch) Parts listing to identify aftermarket replacement parts within the transmission section. This wheel loader application is listed for machine serial 53001-UP; the diagram and parts table retain the selected configuration and its source notes.
The parts table contains 33 listed part occurrences, including torqflow ass'y (reference 714-12-10011), torqflow ass'y (reference 714-12-10010) and clutch ass'y,forward and reverse (reference 714-12-12040). 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.
