Additional Notes

  • All differential fluid capacities across the Claas Lexion 500 series Montana configurations fall into one of two values: 17 liters or 19.5 liters. Both figures represent a combined fill for the differential and axle carrier assembly, meaning the volume accounts for the entire integrated unit rather than the differential housing alone.
  • The 17-liter capacity applies to the Lexion 520 and 530 Montana variants paired with either the CAT 3126B or CAT C6.6 Tier III and C9 Tier III engines, as well as the Lexion 570 Montana with the CAT C12 Tier II and CAT C13 Tier III engines. Despite the difference in engine displacement and output tier between these configurations, the axle assembly capacity remains consistent at 17 liters.
  • The 19.5-liter capacity is specific to the Lexion 550 and 560 Montana variants, covering the CAT C9 Tier II, CAT C9 Tier III, CAT C10 Tier II, and CAT C13 Tier III engine pairings. The higher volume relative to the 17-liter configurations reflects a physically larger differential and axle carrier assembly used in those models.
  • The Lexion 570 Montana carries a 17-liter capacity despite being a higher-numbered model than the 550 and 560 variants, which use 19.5 liters. Capacity in a differential system is determined by the physical size of the housing, not by the model hierarchy or engine power rating.
  • All rows across the 2003-2011 range are designated for normal use conditions. In fluid service specifications, a normal use designation typically refers to standard operating environments without the elevated thermal or load cycling associated with severe-duty classifications.
  • The specifications cover two distinct CAT engine emission tiers: Tier II and Tier III. Within the same model line, such as the Lexion 550 Montana with the CAT C9, both Tier II and Tier III engine variants share an identical 19.5-liter differential capacity, indicating the axle assembly was not revised between emission tier updates for those configurations.
  • The Lexion 560 Montana transitions from the CAT C10 Tier II to the CAT C13 Tier III across the production span. Both engine variants are paired with the same 580 header platform and share the 19.5-liter differential capacity, pointing to a consistent axle carrier design across that engine changeover.
