McCormick CX-L

Differential fluid capacity & service interval

McCormick CX-L differential fluid capacity ranges from 3,5 to 5 liters. Service intervals include checking every 100 hours and changing every 1000 hours or 12 months. The data covers 4 configurations.

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

Additional Notes

  • The McCormick CX-L front differential fluid capacity splits into two distinct groups across the model range: the CX55L and CX65L each hold 3.5 liters, while the CX75L and CX85L each hold 5 liters.
  • The 5-liter capacity of the CX75L and CX85L front differentials represents a 43% increase over the 3.5-liter fill of the smaller variants, reflecting the larger mechanical assemblies associated with higher-output configurations.
  • All four variants share an identical check interval of every 100 hours under normal use conditions, regardless of the capacity difference between the lower and upper model tiers.
  • The change interval across all four models is set at 1000 hours or 12 months under normal use conditions, whichever comes first, applying a time-based ceiling alongside the hour-based threshold.
  • The ratio between the check interval and the change interval is 1:10 across all listed CX-L variants, meaning ten fluid checks are expected to occur within a single full drain-and-fill cycle.
  • All specifications apply to front differential service, indicating a front axle differential assembly separate from any rear drivetrain components.
