Using Komatsu WA250PT-3MC Wheel Loader Lift Arm Parallel Lift Linkage Parts
Use the Komatsu WA250PT-3MC Wheel Loader Lift Arm Parallel Lift Linkage Parts listing to identify aftermarket replacement parts within the work equipment section. This wheel loader application is listed for machine serial A78001-UP; the diagram and parts table retain the selected configuration and its source notes.
The parts table contains 73 listed part occurrences, including arm assembly, lift (reference 418-T80-A100), arm, lift (reference NSS) and bushing (reference 417-70-11860). Read any option and reference notes beside these entries before choosing a replacement; repeated references may represent separate positions in the source list.
For work-equipment parts, check the attachment configuration and any boom, arm, bucket or lift arrangement named in the assembly. Keep capacity, length and left/right distinctions wherever the source provides them.
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.
