Case - IH 33

Power steering fluid capacity & service interval

Case - IH 33 uses power steering fluid with a capacity of 0,2 liter. Service intervals require a check every 200 hours. The data covers 5 configurations.

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

Additional Notes

  • The Case - IH 33 series covers five model variants — the 433, 533, 633, 733, and 833 — all produced from 1985-1992, and all share an identical power steering fluid capacity of 0.2 liter at the steering box.
  • A 0.2 liter capacity is a notably small volume, consistent with a self-contained steering box reservoir rather than a remote hydraulic pump circuit with a separate fluid tank.
  • The service action specified across all five variants is a fluid level check, not a drain-and-fill interval, which reflects a monitoring approach rather than a scheduled replacement cycle.
  • The 200-hour check interval applies under normal use conditions for every variant in the 33 series, with no differentiation by model number or engine size across the range.
  • Because the capacity and interval figures are uniform from the 433 through the 833, the steering box specification appears to be a shared component across the full 33 series lineup for the 1985-1992 production span.
