Additional Notes

  • The front differential capacity of 8 liters applies to the standard (non-suspended) front axle across all Case-IH CVX variants covered in these specifications, from the early CVX 120 through to the CVX 195 and the CVX1135-CVX1195 series.
  • On CVX 120, CVX 130, CVX 150, and CVX 170 models from 2001-2003, the front differential fitted with suspension carries two separate fluid capacities: 2.2 liters and 5.5 liters. These figures correspond to distinct fill points or sub-assemblies within the suspended axle assembly rather than alternative total volumes.
  • CVX 140, CVX 150, CVX 160, CVX 175, and CVX 195 models from 2007-2013 show reduced suspended front differential capacities of 1.5 liters and 4 liters, compared to the 2.2-liter and 5.5-liter figures specified for the 2001-2003 generation, reflecting a difference in axle design between the two production periods.
  • For the CVX1135, CVX1145, CVX1155, CVX1170, CVX1190, and CVX1195 models from 2003-2007, the three front differential capacities — 2.2 liters for the 20.25 suspension, 5.5 liters for the 20.29 suspension, and 8 liters for the standard axle — are listed within a single specification row, with the suspension type serving as the differentiating factor.
  • The CVX1135 through CVX1195 series carries a first-change-only interval of 250 hours or 6 months for the front differential. A shortened initial drain interval of this kind is standard practice for new or rebuilt gear assemblies, allowing metal particles generated during the break-in period to be removed before the regular service schedule begins.
  • Following the first change, the CVX1135-CVX1195 series moves to a normal-use change interval of 1000 hours or 24 months, paired with a fluid level check at 500 hours or 12 months. The 24-month change interval on these models is longer than the 12-month interval specified for the 2001-2003 and 2007-2013 CVX series.
  • The 2001-2003 and 2007-2013 CVX series specifies a front differential fluid check at 250 hours under normal use conditions, while the CVX1135-CVX1195 series sets the equivalent check interval at 500 hours or 12 months. Both series share the same 1000-hour change threshold, but the time-based limit extends to 24 months on the CVX1135-CVX1195 versus 12 months on the earlier and later series.
  • No first-change interval is listed for the front differential on the 2001-2003 CVX 120, CVX 130, CVX 150, and CVX 170 models, nor on the 2007-2013 CVX 140, CVX 150, CVX 160, CVX 175, and CVX 195 models. Only the 2003-2007 CVX1135-CVX1195 series carries a dedicated first-change specification for the front differential.
