Case - IH CVX

Power steering fluid capacity & service interval

Case - IH CVX power steering fluid capacity is 52 liters. Service intervals include checks every 250 hours and changes every 1000 hours or 12 months. The data covers 6 configurations.

Additional Notes

  • The Case-IH CVX power steering system shares its fluid with the broader hydraulic system, meaning the 52-liter capacity figure reflects the combined hydraulic and steering circuit rather than a standalone steering reservoir. A dedicated power steering reservoir would typically hold only a fraction of that volume.
  • All six CVX variants across the 2003-2007 span carry an identical 52-liter hydraulic and power steering fluid capacity, indicating a consistent shared-circuit architecture across the model range regardless of engine output designation.
  • The CVX1135, CVX1145, CVX1155, CVX1170, and CVX1190 share the same 2003-2006 production window, while the CVX1195 carries a 2006-2007 window, making 2006 the only year in which all six variants appear within the specifications simultaneously.
  • The 250-hour check interval is notably shorter than the 1000-hour change interval, reflecting standard agricultural equipment practice where fluid condition and level are monitored well before a full drain-and-fill is required.
  • The change interval is expressed as 1000 hours or 12 months, whichever comes first. In agricultural use, calendar time can be the limiting factor during lower-utilization seasons, even if the hour threshold has not been reached.
  • A 52-liter hydraulic system capacity is substantial even by large tractor standards, and fluid changes at that volume represent a significant service event in terms of fluid quantity and disposal considerations.
