Using Komatsu PC1250-8 Excavator Cylinder Block (#511774-) Parts

Use the Komatsu PC1250-8 Excavator Cylinder Block (#511774-) 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 30158-UP; the diagram and parts table retain the selected configuration and its source notes.

The parts table contains 37 listed part occurrences, including cap, main metal, no.6 (reference 6240-29-1250), cap, main metal, no.1, 2, 3, 4, 5, 7 (reference 6240-29-1210) and tube (reference 6162-23-1140). 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.

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.
