- The D375A-3 and early WA600-3 have different SA6D170E-2 reference ratings: 391 kW at 1,800 rpm versus 328 kW at 2,000 rpm. Confirm machine-specific calibration.

Buying questions
Which WA600-3 serials does Komatsu associate with SA6D170E-2?
The Komatsu shop manual identifies the earlier 50001-52000 group with SA6D170E-2 and later machines with SAA6D170E-3. Check the serial and original engine plate.
Is one power figure valid for both the D375A-3 and WA600-3?
No. Komatsu publishes 391 kW at 1,800 rpm for the D375A-3 reference and 328 kW at 2,000 rpm for the early WA600-3 reference. These are installation ratings, not a guarantee for the offered engine.
