Additional Notes

  • The Case IH Magnum AFS Connect front differential fluid capacity depends directly on which axle class is fitted. The Magnum 180 through 240 AFS Connect Tier 4b models are specified with either a Class 4 axle holding 11 liters or a Class 4.75 axle holding 17.5 liters, a difference of 6.5 liters between the two axle options on the same tractor model.
  • The Magnum 250 through 400 AFS Connect Tier 4b models carry a Class 4.75 axle capacity of 16.5 liters, while the Class 5 axle on the same models holds between 16.5 and 17.5 liters depending on the specific unit. The range notation on the Class 5 axle reflects a fill tolerance rather than a fixed single value.
  • A clear capacity step exists between the lower and upper model groups. The Class 4 axle found on the 180-240 range holds 11 liters, whereas the Class 4.75 axle on the 250-400 range holds 16.5 liters, representing a 5.5-liter increase associated with the heavier axle class used on higher-output models.
  • The service interval for the Magnum 180 through 240 AFS Connect Tier 4b front differential is 1,000 hours or 12 months under normal use conditions, whichever comes first. The dual-trigger format means calendar time alone can require a fluid change even when hour accumulation is low.
  • The Magnum 250 through 400 AFS Connect Tier 4b front differential carries a longer service interval of 1,200 hours or 24 months under normal use conditions. Compared to the lower models, both the hour threshold and the calendar threshold are extended, reflecting the different axle specifications in this group.
  • All ten model variants across the Magnum AFS Connect Tier 4b lineup share the same use condition classification of normal for the front differential service interval. No severe-use interval is listed in the specifications for any of these models.
  • The 200-hour and 12-month difference in service intervals between the two model groups means that a Magnum 240 and a Magnum 250, despite being adjacent in the lineup, follow different fluid change schedules for the front differential, tied to their respective axle class fitments.
