Case - IH JXU Maxxima

Power steering fluid capacity & service interval

Case - IH JXU Maxxima uses power steering fluid with a capacity range of 1,5 to 2 liters. Service intervals include checks at 10 and 300 hours, and changes at 1200 hours or 24 months. The data covers 8 configurations.

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

Additional Notes

  • The Case-IH JXU Maxxima power steering system appears in two distinct capacity ratings across the model range. The JX70U, JX80U, JX90U, and JX100U carry a 1.5-liter capacity, while the JX1070U, JX1080U, JX1090U, and JX1100U each hold 2 liters. A 0.5-liter difference between groups reflects the larger hydraulic steering assemblies fitted to the higher-numbered variants.
  • All eight configurations share a common fluid change interval of 1,200 hours under normal use conditions, indicating a consistent service life expectation for the power steering fluid regardless of model variant.
  • The JX1070U, JX1080U, JX1090U, and JX1100U add a calendar-based change limit of 24 months alongside the 1,200-hour interval. A dual interval of this kind means fluid replacement is due at whichever threshold arrives first, accounting for machines that accumulate fewer operating hours over time.
  • The JX70U, JX80U, JX90U, and JX100U specify a fluid check interval of every 10 hours. In agricultural equipment, a 10-hour check interval is notably short and typically reflects a break-in or early-wear monitoring period, or a system where fluid level is considered safety-critical enough to warrant very frequent inspection.
  • The JX1070U, JX1080U, JX1090U, and JX1100U specify a fluid check interval of 300 hours, which is substantially longer than the 10-hour check interval assigned to the lower-numbered models. The 300-hour figure aligns more closely with standard periodic service checks common in agricultural tractor maintenance schedules.
  • The four models with 2-liter capacity all share production years of 2005-2008, while the 1.5-liter models cover the wider span of 2003-2008. The 1.5-liter group therefore predates the 2-liter group by two model years within the JXU Maxxima lineup.
