Hürlimann XL.K RVSHIFT

Differential fluid capacity & service interval

Hürlimann XL.K RVSHIFT 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 Hürlimann XL.K RVSHIFT front differential holds 9.5 liters across the XL.K 115, XL.K 125, and XL.K 135 variants, indicating a consistent housing design shared among all three configurations in the Stage 5 lineup starting from 2023.
  • A 9.5-liter front differential capacity is a relatively substantial fill volume, which is typical of heavy-duty agricultural axle assemblies where the differential housing also serves lubrication duties for associated gearing under sustained load conditions.
  • The change interval for the front differential fluid is specified at 1,200 hours or 12 months under normal use conditions, meaning whichever threshold is reached first would govern the service timing in practice.
  • The dual-trigger interval structure of 1,200 hours and 12 months reflects the reality that calendar time can degrade fluid chemistry even when operational hours remain low, making the time-based limit relevant for machines with lighter annual workloads.
  • All three variants, the XL.K 115 RVSHIFT, XL.K 125 RVSHIFT, and XL.K 135 RVSHIFT, share identical front differential fluid capacity and change interval specifications, suggesting the front axle assembly is not differentiated by engine output tier within the Stage 5 series beginning at serial numbers ZKDGX20200TH50001, ZKDGX30200TH50001, and ZKDGX40200TH50001 respectively.
