Hyundai Wheeled excavators, HW

Differential fluid capacity & service interval

Hyundai HW wheeled excavators require differential fluid with capacities ranging from 9 to 14 liters. Service intervals include checking at 250 hours and changing at 500 or 1500 hours. The data covers 12 configurations.

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

Additional Notes

  • Across the Cummins QSB 6.7 Tier 4f models spanning 2016-2021, rear differential capacities are consistently higher than front differential capacities, reflecting the greater load-bearing role of the rear axle in wheeled excavator configurations. The HW140 rear differential holds 11.2 liters against a 9-liter front, while the HW160 and HW180 share a 12.5-liter rear capacity against a 10.5-liter front.
  • The Hyundai HW210 carries the largest rear differential capacity among the 2016-2021 Tier 4f lineup at 13.5 liters, paired with a 9.6-liter front differential. The rear figure exceeds that of the HW160 and HW180 despite those models sharing the same front axle capacity.
  • The HW140 front differential capacity of 9 liters is the smallest front axle figure across all listed Tier 4f models, consistent with the HW140 being the lightest machine in the 2016-2021 group.
  • The HW150A CR Stage V introduces an axle width variant that affects both front and rear differential capacities. The wide axle front differential holds 11.6 liters compared to 10.5 liters for the standard axle, and the wide axle rear differential holds 14 liters compared to 12.5 liters for the standard configuration.
  • On the HW150A CR Stage V, a first-change interval is specified at 500 hours for both front and rear differentials. A break-in period fluid change at a shorter interval than the standard cycle is common practice to remove metal particles generated during initial component wear-in.
  • Following the first-change service, the HW150A CR Stage V transitions to a 1500-hour change interval for both front and rear differentials under normal use conditions. A separate check interval of 250 hours is also specified, which involves inspecting fluid level or condition without a full drain and refill.
  • No service interval data in hours is listed for any of the 2016-2021 Cummins QSB 6.7 Tier 4f models across the HW140, HW160, HW180, and HW210. Only capacity values are present in those rows.
  • The HW160 and HW180, both powered by the Cummins QSB 6.7 Tier 4f engine and produced in the 2016-2021 period, share identical front and rear differential capacities of 10.5 liters and 12.5 liters respectively, despite being distinct model designations with different operating weights.
