Assembly notes
Using Komatsu WA470-1 Wheel Loader Fuel Injection Pump And Piping Parts
Use the Komatsu WA470-1 Wheel Loader Fuel Injection Pump And Piping Parts listing to identify aftermarket replacement parts within the engine fuel system 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 41 listed part occurrences, including injection pump a. (reference 6151-71-1450), injection pump a.,(see fig.0451) (reference 6151-71-1151) and injection pump a.,(see fig.0451) (reference 6151-71-1150). Read any option and reference notes beside these entries before choosing a replacement; repeated references may represent separate positions in the source list.
The source engine application is S6D125-1Z (engine serial 21431-UP). Match that engine identification as well as the machine serial range; the general machine model is not a substitute for engine-specific applicability.
Distinguish engine fuel-system parts from machine-side fuel equipment. Match the selected assembly, serial applicability and listed connections before choosing a replacement component.
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.
