Hürlimann XB TB

Power steering fluid capacity & service interval

Hürlimann XB TB uses power steering fluid with a capacity of 52 liters. Service intervals include checking at 300 hours and changing at 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 XB TB power steering fluid system is shared with the transaxle and hydraulic system, meaning the 52-liter capacity figure reflects a combined reservoir rather than a standalone power steering circuit.
  • A 52-liter capacity is notably large and consistent with agricultural tractor hydraulic systems, where a single fluid reservoir serves multiple interconnected functions simultaneously.
  • The XB TB.75, XB TB.85, and XB TB.95 all carry an identical 52-liter capacity across the 2004-2007 model years, indicating no variation in reservoir size across the three engine variants within the range.
  • Under normal use conditions, the specified check interval is every 300 hours, which in tractor operation typically corresponds to a seasonal or periodic inspection point rather than a full drain service.
  • The change interval under normal use is set at 1200 hours or 12 months, whichever comes first, establishing a dual threshold that accounts for both operational intensity and calendar-based fluid degradation.
  • The 12-month calendar limit on fluid changes means that even low-hour machines reaching the one-year mark are subject to a full fluid replacement, regardless of accumulated operating hours.
