Case - IH CS

Brake fluid capacity & service interval

Case IH CS models require brake fluid with a capacity range of 0,4 to 0,75 liters. Service intervals include checks at 50 and 500 hours, and fluid changes at 24 months or 1000 hours. The data covers 7 configurations.

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

Additional Notes

  • The Case-IH CS series brake fluid specifications cover two distinct capacity values across the model range: 0.75 liter for the CS 110, CS 120, CS 130, and CS 150, and 0.4 liter for the CS 78, CS 86, and CS 94. The smaller capacity in the lower-numbered models reflects a more compact hydraulic brake circuit relative to the larger tractors in the lineup.
  • The CS 110, CS 120, CS 130, and CS 150 all share a time-based change interval of 24 months, regardless of operating hours accumulated. A calendar-based interval of this kind is common in hydraulic brake systems where fluid degradation is driven by moisture absorption and oxidation over time rather than mechanical wear cycles alone.
  • The CS 78, CS 86, and CS 94 use an hours-based service schedule, with a check interval at 500 hours and a full fluid change at 1,000 hours. Hour-based intervals are typical in agricultural equipment where annual operating time can vary widely, making a fixed calendar schedule less reliable as a maintenance trigger.
  • The check interval for the CS 110, CS 120, CS 130, and CS 150 is set at 50 hours, which is considerably more frequent than the 500-hour check interval on the CS 78, CS 86, and CS 94. A 50-hour check interval is generally associated with systems where early detection of fluid level changes or contamination is considered more critical to safe operation.
  • All seven models in the CS series specify a 0.75-liter or 0.4-liter service fill capacity for the hydraulic brake system under normal use conditions. These figures represent the working fluid volume of the system rather than an overhaul or dry-fill quantity, meaning actual fluid required during a change may differ slightly depending on residual fluid retained in the circuit.
  • The CS 150, introduced in 1997, shares the same 0.75-liter capacity and 24-month change interval as the CS 110, CS 120, and CS 130, despite being the highest-numbered and presumably most powerful model in the group. Uniform brake fluid specifications across different power ratings within a platform are common when the hydraulic brake circuit architecture remains consistent across variants.
  • The CS 78, CS 86, and CS 94 were all introduced in 1997, while the CS 110 entered production in 1999 and the CS 120 and CS 130 in 1998. The differing introduction years correspond to the two separate service interval structures seen across the CS range, with the earlier lower-horsepower models using the hours-based schedule and the later models using the time-based schedule.
