Hürlimann XL.K

Differential fluid capacity & service interval

Hürlimann XL.K uses differential fluid with a capacity of 9,5 liters. Service intervals occur every 1200 hours or 12 months. The data covers 3 configurations.

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

Additional Notes

  • The front differential fluid capacity for the Hürlimann XL.K 115, XL.K 125, and XL.K 135 (Stage 5, from serial numbers ZKDGW10200TH50001, ZKDGW20200TH50001, and ZKDGW30200TH50001 respectively, starting 2022) is 9.5 liters across all three variants.
  • A 9.5-liter front differential capacity is a relatively substantial fill volume, consistent with heavy-duty agricultural axle assemblies where larger fluid reservoirs support sustained load-bearing and thermal management demands.
  • The front differential fluid change interval is set at 1,200 hours or 12 months under normal use conditions, whichever comes first, applying uniformly to the XL.K 115, XL.K 125, and XL.K 135.
  • The dual-trigger interval structure of 1,200 hours or 12 months means that even in lower-utilization applications where the hour threshold may not be reached within a calendar year, the 12-month mark still governs the fluid change under normal use conditions.
  • No variation in front differential fluid capacity or change interval exists across the XL.K 115, XL.K 125, and XL.K 135 configurations, despite the three models representing distinct power output tiers within the same Stage 5 series.
