Case - IH CS

Power steering fluid capacity & service interval

Case - IH CS power steering fluid capacity ranges from 30 to 76 liters. Service intervals include checks at 500 hours and changes at 1000 hours or 12 months. The data covers 7 configurations.

The configuration chart below lists fill volumes and service intervals for each engine and trim variant.

Additional Notes

  • Across the Case-IH CS series, power steering fluid is part of a shared reservoir system rather than a dedicated standalone circuit. In the CS 110, CS 120, CS 130, and CS 150, the fluid serves the transaxle, hydraulic system, and power steering simultaneously, while in the CS 78, CS 86, and CS 94, the shared system covers the hydraulic system and power steering without the transaxle.
  • The 76-liter capacity specified for the CS 110, CS 120, CS 130, and CS 150 reflects the combined volume of a large integrated system. A figure of that size is consistent with a full-system service fill rather than a top-up or partial service quantity.
  • The CS 78, CS 86, and CS 94 carry a 30-liter capacity for their shared hydraulic and power steering system. The reduction compared to the larger CS models aligns with the absence of the transaxle from the shared circuit in those configurations.
  • All seven CS variants share the same check interval of 500 hours under normal use conditions, regardless of system capacity or model year range.
  • The change interval for the CS 110, CS 120, CS 130, and CS 150 is set at 1000 hours or 12 months under normal use, whichever comes first. The addition of a calendar-based threshold alongside the hour-based one means the fluid is subject to replacement even in lower-utilization applications where 1000 operating hours may not be reached within a year.
  • The CS 78, CS 86, and CS 94 specify a change interval of 1000 hours under normal use with no accompanying calendar interval. Unlike the larger CS models, the service schedule for these variants is governed solely by operating hours.
  • The CS 110 carries a model year range of 1999-2004, starting two years later than the CS 78, CS 86, CS 94, and CS 150, which all begin in 1997. The CS 120 and CS 130 share a 1998-2004 range, placing them between the two groups in terms of introduction year.
