Case - IH 94

Differential fluid capacity & service interval

Case - IH 94 uses differential fluid with a capacity range of 5 to 6 liters. Service intervals include a 100 hour check and an 800 hour change. The data covers 5 configurations.

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

Additional Notes

  • The front differential on the Case-IH 94 series carries either 5 or 6 liters of fluid depending on the specific model, indicating a meaningful capacity difference across the lineup despite shared service intervals.
  • The 1294, 1394, and 1494 models all share a 6-liter front differential capacity, while the 1594 and 1694 each hold 5 liters, placing the two groups in distinct fill categories.
  • A 6-liter fill volume for the front differential on the 1294, 1394, and 1494 reflects a larger housing or gear assembly compared to the 5-liter units found on the 1594 and 1694.
  • All five models in the 94 series share a 100-hour front differential check interval under normal use conditions, meaning fluid level verification is a relatively frequent task relative to the full change cycle.
  • The front differential fluid change interval across all listed 94 series models is 800 hours under normal use, a figure that represents a substantial portion of annual operating time for a working tractor.
  • The ratio of check interval to change interval is 1:8 across all listed configurations, with a 100-hour check preceding a full fluid change at 800 hours.
  • The 1294 has a production window of 1984-1985, the shortest span among the listed models, yet shares the same 6-liter capacity and 800-hour change interval as the longer-running 1394 and 1494.
  • The 1394 covers model years 1984-1987 and maintains the same 6-liter front differential capacity and service intervals as both the earlier 1294 and the concurrent 1494.
