Use the Komatsu PC1250LC-8 Excavator Fuel Injector (#511700-) Parts listing to identify aftermarket replacement parts within the engine fuel system section. This excavator application is listed for machine serial 30158-UP; the diagram and parts table retain the selected configuration and its source notes.

The parts table contains 13 listed part occurrences, including injector assembly (reference 6245-11-3100), gasket (reference 6261-71-6150) and holder, injector (reference 6245-71-1160). 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 SAA6D170E-5C (engine serial 511700-UP). Match that engine identification as well as the machine serial range; the general machine model is not a substitute for engine-specific applicability.
