Using Komatsu WA320-1 Wheel Loader Alternator (35A) Parts
Use the Komatsu WA320-1 Wheel Loader Alternator (35A) Parts listing to identify aftermarket replacement parts within the engine electrical system 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 37 listed part occurrences, including alternator a. (35a) (reference 600-821-7420), rotor ass'y (reference KD1-33100-1270) and bearing,ball, front (reference KD1-0456-63057). 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 S6D105-1SS (engine serial 86535-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 electrical parts, compare the component reference and any voltage, connector or equipment-option notes shown in the listing. A similar description or shape alone is not a compatibility check.
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.
