Using Komatsu WA380-5 Wheel Loader Transmission Main Valve (Var.1) Parts
Use the Komatsu WA380-5 Wheel Loader Transmission Main Valve (Var.1) Parts listing to identify aftermarket replacement parts within the f0 transmission section. This wheel loader application is listed for machine serial H50051 - UP; the diagram and parts table retain the selected configuration and its source notes.
The parts table contains 40 listed part occurrences, including valve assembly (reference 714-12-25000), valve seat (reference 714-12-25132) and plug (reference 07043-70108). 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.
