Additional Notes

  • All Tier 4b/Stage IV variants across the Maxxum 115, 125, 135, 145, and 150 CVX share a single front differential capacity of 9 liters, with no axle-class variation listed for those configurations.
  • Stage V variants of the Case-IH Maxxum CVX introduce a second front differential capacity figure of 11 liters, applicable specifically to Class 4 axle fitments. The standard capacity of 9 liters remains listed alongside, indicating the two values correspond to different axle specifications rather than a general increase.
  • A Class 4 axle is a heavier-duty front axle design, and the additional 2-liter capacity in Stage V configurations reflects the larger housing volume associated with that axle type.
  • The front differential check interval is 300 hours across all listed configurations, covering both Tier 4b/Stage IV and Stage V variants regardless of model number.
  • The fluid change interval is consistent at 1,200 hours or 12 months across every listed configuration. The dual-condition format means whichever threshold is reached first governs the service event, a standard approach for time- and usage-based maintenance scheduling.
  • All specifications are designated for normal use conditions. No severe-use intervals are listed for any of the front differential entries across the Maxxum CVX range.
  • The Tier 4b/Stage IV configurations span 2016-2020 across all five model variants, while Stage V configurations begin from 2020, meaning both emission tiers share the same 9-liter standard capacity and identical service intervals at that transition point.
