Additional Notes

  • Front differential capacities across the Case-IH JXU Maxxima range fall into three distinct groups: 4.5 liters, 7 liters, and 7.5 liters, reflecting differences in axle assembly size between models.
  • The JX70U Maxxima carries a 4.5-liter front differential capacity, while the JX80U and JX90U Maxxima both require 7.5 liters, representing a significant volume difference between models sharing the same 2003-2008 production span.
  • The JX100U Maxxima specifies a 7.5-liter front differential capacity, the largest among all models in the range, indicating a heavier-duty axle assembly relative to the smaller-displacement variants.
  • Among the 2005-2008 models, the JX1070U and JX1080U Maxxima share a 4.5-liter front differential capacity, while the JX1090U and JX1100U Maxxima each require 7 liters, placing them in a mid-range capacity class distinct from both the 4.5-liter and 7.5-liter groups.
  • All models in the range share a uniform check interval of 300 hours under normal use conditions, regardless of capacity differences between models.
  • The 2003-2008 models, specifically the JX70U, JX80U, JX90U, and JX100U Maxxima, specify a change interval of 1200 hours with no calendar-based alternative, meaning the interval is defined solely by operating hours.
  • The 2005-2008 models add a 24-month calendar limit alongside the 1200-hour change interval, meaning fluid replacement is due at whichever threshold is reached first, whether by accumulated operating hours or elapsed time.
