Buyer guide

Read the complete Komatsu model code

Komatsu listings include SAA6D114E-2, SA6D170E-3 and SAA12V140E-3 families. Keep the final suffix when comparing them: a nearby suffix may represent a different machine installation or engine specification. Match the engine plate with the equipment serial and the hydraulic or transmission drive.

The SA6D140E-2 generator listings need a separate package check. Confirm governed speed, flywheel or coupling interface, controls and cooling rather than assuming that a machinery assembly has the same configuration. The listing identifies an engine assembly, not a complete generator set.

What to check before ordering

  • Record every character of the model suffix and engine serial number.
  • Check the machine serial and the driven pump, transmission or generator connection.
  • Confirm whether the selected listing is a machinery or generator engine assembly.

Useful answers

Frequently asked questions

Does a matching SA or SAA family name confirm fit?

No. The complete suffix, equipment serial and physical installation must also match.

Is the SA6D140E-2 generator listing a complete genset?

It is listed as an engine assembly. Confirm separately whether any alternator, base frame or other generator components are supplied.

How do I resolve a suffix difference in a listing?
