Hyundai Forklift trucks, diesel

AdBlue (DEF) capacity & service interval

Hyundai Forklift trucks, diesel use AdBlue (DEF) with a capacity range of 18,9 to 37,8 liters. The data covers 6 configurations.

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

Additional Notes

  • The Hyundai diesel forklift trucks in the 110D-9, 130D-9, 160D-9, 160D-9L, and 180D-9B models all share the Cummins QSB6.7 T4f engine and carry a uniform AdBlue (DEF) tank capacity of 37.8 liters across all five configurations.
  • The 80D-9, fitted with the smaller Cummins QSF 3.8 engine, holds an AdBlue tank capacity of 18.9 liters, which is exactly half the volume specified for the QSB6.7 T4f-equipped models.
  • AdBlue, also known as Diesel Exhaust Fluid (DEF), is a urea-water solution consumed by selective catalytic reduction (SCR) systems to reduce nitrogen oxide (NOx) emissions in diesel engines meeting Tier 4 Final (T4f) emissions standards.
  • The 37.8-liter AdBlue capacity on the QSB6.7 T4f models is a service fill figure, representing the total volume the SCR tank holds during normal operation rather than a dry-fill or overhaul measurement.
  • All six forklift models listed carry a normal use condition designation for AdBlue capacity, meaning the 37.8-liter and 18.9-liter figures apply to standard operating environments without adjustment for severe-duty cycles.
  • The Cummins QSF 3.8 is a smaller-displacement inline four-cylinder engine compared to the six-cylinder QSB6.7, and the proportionally smaller 18.9-liter DEF tank reflects the lower exhaust volume and corresponding SCR fluid consumption of the smaller engine.
  • The 160D-9 and 160D-9L share the same Cummins QSB6.7 T4f engine and identical 37.8-liter AdBlue capacity, indicating the "L" variant designation reflects a configuration difference unrelated to the SCR system or fluid volume.
