Additional Notes
- The Komatsu HD325-8 equipped with the SAA6D140E-7 engine carries an AdBlue (DEF) system capacity of 34.7 liters, a figure consistent with the tank sizing typically found on heavy-duty mining and construction equipment where extended operational cycles demand larger fluid reserves between refills.
- The 34.7-liter capacity listed for the HD325-8 reflects a service fill volume associated with normal use conditions, meaning the figure applies to standard operating environments rather than severe-duty cycles that might alter consumption rates or service timing.
- The AdBlue system on the HD325-8 is identified as a selective catalytic reduction (SCR) system, which is the emissions control technology that consumes DEF fluid by injecting it into the exhaust stream to convert nitrogen oxides into nitrogen and water, making the tank capacity directly tied to the vehicle's emissions compliance operation across the 2018-2021 model years.
