Using Komatsu WA250-1 4Th Clutch (Electrical Control Type) Parts
Use the Komatsu WA250-1 4Th Clutch (Electrical Control Type) Parts listing to identify aftermarket replacement parts within the torque converter and transmission section. This wheel loader application is listed for machine serial 10001-UP; the diagram and parts table retain the selected configuration and its source notes.
The parts table contains 33 listed part occurrences, including transmission ass'y,(without emergency steering) (reference 418-15-11050), transmission ass'y,(with emergency steering) (reference 418-15-11060) and clutch ass'y,2nd and 4th (reference 418-15-11202). 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.
