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 50 listed part occurrences, including pump assembly, fuel injection (reference 6245-71-1101), body assembly (reference ND094100-0490) and housing assembly (reference ND094110-0230). 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.
