Komatsu Parts by Serial Range helps buyers verify replacement parts when a machine model was produced with multiple arrangements, component revisions, or serial-number breaks.
Why Serial Range Matters
A Komatsu model designation alone may not be enough to identify the correct replacement part. Pins, bushings, pumps, cylinders, valves, engine components, filters, seals, and other parts can change during a production run. Matching the machine serial number to the correct parts-book range reduces the risk of ordering a visually similar but incompatible component.
Information to Gather
- Complete machine model.
- Machine serial number or PIN.
- Original part number, if available.
- Component group or diagram position.
- Any casting, plate, or installed-component identification.
