McCormick S-Max
Differential fluid capacity & service interval
McCormick S-Max differential fluid capacity ranges from 5,5 to 6,5 liters. Service intervals require changes every 1000 hours or 12 months. The data covers 6 configurations.
The configuration chart below lists fill volumes and service intervals for each engine and trim variant.

Additional Notes
- The McCormick S-Max front differential holds 5.5 liters across the S45 (ITL 3102 IL), S50 (ITL 3105 EL), S60 (ITL 3100 FLT), S75 (ITL 4100 FLT/ELT), and S90 (ITL 4105 FLT/ELT) configurations, indicating a consistent axle housing volume shared across multiple engine and transmission variants in the range.
- The S60 with the ITL 4100 FL transmission stands apart from all other S-Max configurations, carrying a front differential capacity of 6.5 liters rather than the 5.5-liter figure seen elsewhere, reflecting a different axle unit paired with that specific drivetrain.
- The ITL 4100 FL-equipped S60 also lists an alternative capacity of 5.6 liters specifically for the Carraro axle variant. The two capacity values for the same model indicate that different front axle manufacturers were fitted, each requiring a distinct fluid fill volume.
- A Carraro front axle is a unit sourced from the Italian manufacturer Carraro S.p.A., which supplies agricultural and off-highway axle assemblies to multiple tractor brands. The separate capacity figure for the Carraro axle in the S60 ITL 4100 FL reflects the internal volume differences of that supplier's housing design.
- All six S-Max front differential configurations share an identical service interval of 1,000 hours or 12 months under normal use conditions, whichever comes first. The dual-trigger format means the fluid is replaced at the earlier of the two thresholds, preventing extended service gaps in low-usage applications where hours accumulate slowly.
- The 1,000-hour interval is a common benchmark in agricultural equipment servicing, roughly corresponding to one to two seasons of active field use depending on operational intensity. At this interval, differential fluid is changed to remove accumulated metal particles and degraded lubricant before wear rates increase.
- All specifications apply to 2019-onward production for each listed configuration, covering the S45, S50, S60, S75, and S90 variants across both three-cylinder (ITL 3xxx) and four-cylinder (ITL 4xxx) engine families.
