Case - IH 43/45

Brake fluid capacity & service interval

Case - IH 43/45 uses brake fluid with a capacity of 0,5 liter. Service intervals include checking every 50 hours and changing every 1000 hours. The data covers 3 configurations.

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

Additional Notes

  • The hydraulic brake system capacity across the 743 XL, 745 XL, and 845 XL/XLA is 0.5 liter, which represents the service fill volume for the brake fluid reservoir rather than a full system overhaul quantity.
  • A check interval of 50 hours applies to all three configurations, meaning brake fluid condition and level are to be inspected at relatively frequent points within normal operation.
  • The change interval is set at 1000 hours across the 743 XL, 745 XL, and 845 XL/XLA, reflecting a long-cycle replacement schedule typical of hydraulic brake systems in agricultural machinery operating under normal use conditions.
  • All three configurations share identical capacity, check, and change values, indicating no variation in brake fluid specifications between the 743 XL, 745 XL, and 845 XL/XLA within the 1985-1990 production span.
  • The 845 XL/XLA designation covers two trim variants within a single specification entry, both carrying the same 0.5 liter capacity and the same 50-hour check and 1000-hour change intervals.
