Komatsu Wheeled excavators, PW

AdBlue (DEF) capacity & service interval

Komatsu wheeled excavators, PW, utilize AdBlue (DEF) with a capacity range of 29,6 to 30 liters. The data covers 2 configurations.

The configuration chart below lists fill volumes and service intervals for each engine and trim variant.

TypeSpecifications
PW160-11, Komatsu SAA4D107E-3 (2018- )
  • Use: Normal
  • Capacity 30 liter
PW180-11, Komatsu SAA4D107E-3 (2018- )
  • Use: Normal
  • Capacity 29,6 liter

Additional Notes

  • The Komatsu PW160-11, paired with the SAA4D107E-3 engine from 2018, carries an AdBlue (DEF) tank capacity of 30 liters within its selective catalytic reduction system.
  • The PW180-11, also fitted with the SAA4D107E-3 engine from 2018, holds a slightly smaller AdBlue capacity of 29.6 liters in the same SCR configuration.
  • The 0.4-liter difference in AdBlue tank capacity between the PW160-11 and PW180-11 reflects a variation in tank sizing across two models sharing the same engine family.
  • Both capacity figures represent the full tank fill volume under normal use conditions, which in fluid service terminology refers to standard operating environments rather than severe-duty cycles.
  • A 30-liter AdBlue tank, as found on the PW160-11, is a relatively large reservoir for a wheeled excavator, indicating an extended operating range between refill intervals under normal use.
