Using Komatsu WA250-1 Wheel Loader Piston And Connecting Rod Parts
Use the Komatsu WA250-1 Wheel Loader Piston And Connecting Rod Parts listing to identify aftermarket replacement parts within the engine cylinder block section. This wheel loader application is listed for machine serial 10001-UP; the diagram and parts table retain the selected configuration and its source notes.
The parts table contains 15 listed part occurrences, including piston ass'y (reference 6137-32-2030), piston (reference 6137-32-2130) and pin (reference 6137-31-2410). 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 S6D105-1TT (engine serial 86423-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.
