Additional Notes

  • The Claas Lexion 700 series front differential fluid capacity splits into two distinct values depending on the variant. The Lexion 740 and 750 in standard configuration hold 7.7 liters at the front differential, while the same models equipped with a differential lock require 12 liters for the front differential assembly.
  • The 12-liter front differential capacity on the Lexion 740 and 750 TerraTrac variants applies when the differential lock is integrated into the front axle housing, reflecting the additional fluid volume needed to fill the expanded internal components of a locking differential unit.
  • The Lexion 760 and 780 front differentials are specified at 12 liters regardless of whether a differential lock is present, meaning both the standard front differential and the front differential with lock share the same capacity value across those variants.
  • The Lexion 730 front differential holds 7.7 liters, which is the same value listed for the standard (non-locking) front differential on the Lexion 740 and 750, indicating a shared axle specification at that configuration level.
  • Rear differential capacity remains consistent at 7.5 liters across the Lexion 730, 740, 750, and 760 variants for the 2016-2020 period, pointing to a common rear axle assembly used across those models.
  • The Lexion 780 rear differential departs from the 7.5-liter figure seen on lower variants, carrying a 12-liter capacity. A rear differential requiring 12 liters typically indicates a larger or more heavily built axle housing suited to higher load or torque demands.
  • All differential fluid capacities across the Lexion 700 series are listed under normal use conditions, meaning the specified volumes apply to standard operating environments rather than severe-duty or extended-interval scenarios.
  • The front differential on the Lexion 740 and 750 is the only position in the series where two distinct capacity values appear for the same model year range, with the 7.7-liter figure tied explicitly to the standard configuration and the 12-liter figure tied to the differential lock configuration.
