Hyundai Wheeled excavators, HW

Automatic transmission fluid capacity & service interval

Hyundai HW wheeled excavators require automatic transmission fluid with a capacity of 2,5 liters. Service intervals include changes at 250 hours and 1000 hours. The data covers 6 configurations.

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

Additional Notes

  • The powershift transmission in the Hyundai HW140, HW160, HW180, and HW210 wheeled excavators equipped with the Cummins QSB 6.7 Tier 4f engine all share an identical automatic transmission fluid capacity of 2.5 liters under normal use conditions.
  • A 2.5-liter figure for a powershift transmission represents a service fill volume, which is the working fluid level maintained during normal operation rather than a full overhaul or dry-fill quantity.
  • The HW150A CR Stage V powershift transmission carries the same 2.5-liter capacity as the Cummins QSB 6.7 Tier 4f models, placing all listed HW wheeled excavator variants at a consistent service fill level regardless of engine generation.
  • The HW150A CR Stage V specifies a normal-use automatic transmission fluid change interval of 1,000 hours, which is a standard heavy equipment service threshold aligned with extended drain intervals common in modern powershift systems.
  • A separate first-change-only interval of 250 hours applies to the HW150A CR Stage V powershift transmission. An early first drain at 250 hours is standard practice for new or rebuilt transmissions, as it removes metallic particles and manufacturing residues generated during initial break-in wear.
  • The Cummins QSB 6.7 Tier 4f variants covering model years 2016-2021 carry no change interval in the listed specifications, while the Stage V HW150A CR from 2022 onward includes both a first-change and a recurring normal-use interval, reflecting a difference in the level of service detail recorded between the two engine generations.
