Case - IH Optum CVT

Differential fluid capacity & service interval

Case - IH Optum CVT differential fluid capacity is 17 liters. Service intervals include checking at 300 hours and changing at 1200 hours or 12 months. The data covers 2 configurations.

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

Additional Notes

  • Both the Case IH Optum 270 CVT and Optum 300 CVT share an identical front differential fluid capacity of 17 liters, which represents the service fill volume for normal operating conditions.
  • The front differential on both models calls for a fluid level check at every 300 hours of operation under normal use conditions.
  • The change interval for front differential fluid is set at 1,200 hours or 12 months, whichever comes first, under normal use conditions, meaning both a time-based and an hours-based threshold govern when a drain and refill is due.
  • The 12-month calendar interval running alongside the 1,200-hour threshold reflects that fluid degradation can occur through time-related factors such as moisture absorption and oxidation, independent of machine hours accumulated.
  • Despite the Optum 270 CVT and Optum 300 CVT representing different power output ratings, the front differential fluid capacity and all associated service intervals are identical across both configurations starting from 2016.
