Using Komatsu WA470-1 Wheel Loader Cylinder Head(#26751-) Parts

Use the Komatsu WA470-1 Wheel Loader Cylinder Head(#26751-) Parts listing to identify aftermarket replacement parts within the engine cylinder head 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 36 listed part occurrences, including cylinder head ass'y,valve less (reference 6151-11-1100), sleeve (reference 6136-11-1130) and insert,intake valve (std) (reference 6150-11-1331). 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 S6D125-1Z (engine serial 21431-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.
