Case - IH 4000

Differential fluid capacity & service interval

Case - IH 4000 differential fluid capacity ranges from 20 to 22,7 liters. Service intervals include checking at 10 and 100 hours and changing at 1000 hours. The data covers 4 configurations.

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

Additional Notes

  • The Case-IH 4694 front differential holds 22.7 liters, while the 4894 front differential holds 20 liters, reflecting a capacity difference of 2.7 liters between the two models in the same model year range.
  • The 4694 rear differential also carries a 22.7-liter capacity, matching the front differential fill volume on that model exactly.
  • On the 4894, the rear differential capacity of 20 liters mirrors the front differential, meaning both axle positions share an identical service fill volume on that model.
  • Front differentials on both the 4694 and 4894 require a fluid level check at 10-hour intervals under normal use conditions, a notably short inspection cycle that reflects the load demands placed on front axle differentials in heavy equipment operation.
  • Rear differentials on both models carry a 100-hour check interval under normal use conditions, ten times longer than the front differential check interval, indicating a less frequent monitoring requirement for the rear axle position.
  • Fluid changes for all four differential positions across both models are specified at 1000 hours under normal use conditions, establishing a consistent drain-and-refill interval regardless of axle position or model variant.
