Hürlimann XN
Differential fluid capacity & service interval
Hürlimann XN differential fluid capacity is 6 liters. Service intervals include checking every 150 hours and changing every 1200 hours. The data covers 4 configurations.

Additional Notes
- All four Hürlimann XN variants covered here — the XN 706, XN 707, XN 708, and XN 709 — share identical front differential fluid specifications across the 1998-2005 production span.
- The front differential fluid capacity is 6 liters for each of the four XN variants, a figure consistent with a service fill rather than a full overhaul or dry-fill volume.
- Under normal use conditions, the front differential fluid check interval is set at 150 hours of operation, a relatively short inspection cycle that reflects the mechanical demands placed on front differential assemblies in agricultural equipment.
- The fluid change interval under normal use conditions is 1200 hours, meaning a single change cycle spans eight times the length of the check interval, allowing for multiple inspections before a full drain and refill is due.
- The ratio of check interval to change interval — 150 hours versus 1200 hours — means the front differential fluid would be inspected approximately eight times before a scheduled change is reached under normal operating conditions.
- The uniformity of the 6-liter capacity and the 150-hour check and 1200-hour change intervals across the XN 706, XN 707, XN 708, and XN 709 suggests a shared front axle and differential assembly design across the entire XN series within the 1998-2005 range.
