Using Komatsu PC400-8 Exhaust Muffler And Mounting Bracket (#560004-) Parts
Use the Komatsu PC400-8 Exhaust Muffler And Mounting Bracket (#560004-) Parts listing to identify aftermarket replacement parts within the engine cylinder head and its related parts section. This excavator application is listed for machine serial 70001-UP; the diagram and parts table retain the selected configuration and its source notes.
The parts table contains 23 listed part occurrences, including muffler (reference 6251-11-5440), u-bolt (reference 6222-11-5940) and bracket (reference 6156-11-3510). 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-5F (engine serial 562304-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-head and related engine parts, follow the applicability attached to the selected assembly. Gaskets, fasteners and other components must be checked by their listed references rather than assumed to interchange between engine versions.
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.
