Using Komatsu WA320-1 Engine Cylinder Block Parts

The Komatsu WA320-1 Engine Cylinder Block 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 Front Cover And Gear and Flywheel And Flywheel Housing. 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 S6D105-1AJ (engine serial 86535-UP) and S6D105-1SS (engine serial 86535-UP). Check the engine model and engine serial details on the chosen assembly before ordering Komatsu WA320-1 replacement parts.

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.

Open a WA320-1 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.
