Assembly notes
Using Komatsu WA500-1 Air Compressor (Inner Parts)(#20520-) Parts
Use the Komatsu WA500-1 Air Compressor (Inner Parts)(#20520-) Parts listing to identify aftermarket replacement parts within the engine section. This wheel loader application is listed for machine serial 10001-UP (OVERSEAS VERSION); the diagram and parts table retain the selected configuration and its source notes.
The parts table contains 42 listed part occurrences, including air compressor ass'y (reference 6210-81-3113), case,crank (reference DK487000-6500) and crankshaft (reference DK487653-0300). 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 S6D140-1A-F (engine serial 10001-UP). Match that engine identification as well as the machine serial range; the general machine model is not a substitute for engine-specific applicability.
Use the section and assembly descriptions together with the stated machine application. Preserve location, option and revision notes shown beside each part number when selecting a replacement or preparing a quote.
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.
