Using Komatsu PC1250-8 Excavator Engine Oil Pump (#511700-) Parts
Use the Komatsu PC1250-8 Excavator Engine Oil Pump (#511700-) Parts listing to identify aftermarket replacement parts within the engine lubrication 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 22 listed part occurrences, including pump assembly (reference 6240-51-1100), body assembly (reference 6240-51-1130) and bushing (reference 6151-51-1421). 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 lubrication-system components, match the engine application and the notes attached to the part number. This catalog identifies parts; it does not replace the service manual for lubricant selection or maintenance procedures.
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.
