Using Komatsu PC400-8 Excavator Crankshaft (#660001-) Parts
Use the Komatsu PC400-8 Excavator Crankshaft (#660001-) Parts listing to identify aftermarket replacement parts within the engine cylinder block and its related parts section. This excavator application is listed for machine serial 75001-UP; the diagram and parts table retain the selected configuration and its source notes.
The parts table contains 13 listed part occurrences, including crankshaft assembly (reference 6151-35-1010), gear, crankshaft (reference 6150-35-1120) and key (reference 6150-31-1130). 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 SAA6D125E-5-FR (engine serial 660001-UP). Match that engine identification as well as the machine serial range; the general machine model is not a substitute for engine-specific applicability.
For cylinder-block and related engine components, compare the listed engine serial break and every row-specific option. Use the individual part reference rather than the diagram appearance to distinguish revisions.
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.
