Using Komatsu WA270-7 Engine Electrical System Parts

The Komatsu WA270-7 Engine Electrical System Parts catalog section brings together 4 published assembly listings for identifying aftermarket replacement parts. Start with the component or assembly that matches your machine, then use its diagram and part numbers to narrow the selection.

Available listings include Alternator Cover, For 60Amp, Alternator Cover, For 90Amp, Wiring Harness (Awr00-001001) and Wiring Harness Bracket. These are examples of the published coverage, not a statement that every configuration or service component is included.

Engine-specific listings in this section reference SAA6D107E-2G (engine serial 26601326-UP). Check the engine model and engine serial details on the chosen assembly before ordering Komatsu WA270-7 replacement parts.

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.

Open a WA270-7 assembly to compare the machine serial range, component description, quantities and listed options. You can then select available store matches for the cart or prepare a request for a quote with the part numbers and quantities you need.
