Hürlimann SX

Differential fluid capacity & service interval

Hürlimann SX differential fluid capacity is 13 liters. Service intervals include checking every 50 hours and changing every 12 months. The data covers 6 configurations.

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

Additional Notes

  • All six Hürlimann SX variants covered by these specifications share an identical front differential fluid capacity of 13 liters, indicating a uniform front axle assembly across the SX lineup regardless of model designation.
  • A 13-liter capacity is a substantial fill volume for a front differential, consistent with heavy-duty agricultural tractor axle housings that integrate the differential gear set within a larger shared casing rather than a standalone unit.
  • The SX 1200, SX 1350, and SX 1500 share a production window of 1999-2010, while the SX 1600, SX 1800, and SX 2000 entered production one year later in 2000, though all six converge on the same 2010 endpoint within these specifications.
  • The check interval of 50 hours applies uniformly across all six models under normal use conditions. In agricultural equipment, a 50-hour check interval reflects the high operational intensity of tractor work, where 50 hours can accumulate within a matter of weeks during peak seasons.
  • The fluid change interval is specified as 12 months across all models under normal use conditions, establishing a calendar-based rather than purely hour-based replacement schedule for the front differential fluid.
  • A time-based change interval of 12 months, independent of accumulated operating hours, accounts for fluid degradation from moisture ingress, thermal cycling, and oxidation that occurs even during periods of low or intermittent use.
  • The consistent application of normal use conditions across all six rows means the specified 50-hour check and 12-month change intervals are not adjusted for more demanding operating environments in these specifications.
