Etec Wheeled loaders

Differential fluid capacity & service interval

Etec wheeled loaders use differential fluid with a capacity range of 15 to 45 liters. The service interval for fluid changes is 2000 hours. The data covers 10 configurations.

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

Additional Notes

  • Across all five Etec Wheeled Loaders variants listed, the differential fluid change interval is 2000 hours under normal use conditions, applying equally to both front and rear differentials on every model.
  • The 2020-II carries a front differential capacity of 16 liters and a rear differential capacity of 15 liters, making the total combined differential fluid volume 31 liters for a full service fill.
  • The 2025-II shows a notably larger front differential capacity of 31 liters compared to the 2020-II's 16 liters, indicating a substantially different axle assembly despite sharing the same Doosan DL06 engine.
  • On the 2025-II, the rear differential holds 24 liters against the front's 31 liters, a 7-liter difference that reflects the distinct mechanical design of each axle housing in that configuration.
  • The 2030-II, powered by the Doosan DL08, carries the largest front differential capacity among the DL-series models at 38 liters, with the rear differential specified at 30 liters.
  • The 2040-II, fitted with the Cummins QSL9, holds the highest front differential capacity across all listed variants at 45 liters, with the rear differential specified at 42 liters, giving a combined total of 87 liters.
  • The 2050-II, powered by the Cummins QSM11, is the only variant where front and rear differential capacities are equal, both specified at 32 liters, for a combined total of 64 liters.
  • The front differential consistently holds more fluid than the rear across the 2020-II, 2025-II, 2030-II, and 2040-II variants, with the capacity gap ranging from 1 liter on the 2020-II to 3 liters on the 2040-II.
