Additional Notes

  • The transfer case fluid capacity across all Claas Lexion 7000 configurations listed — the 7400, 7500, 7600, and 7700 — is uniformly 3.75 liters. In agricultural machinery, a transfer case of this size typically serves to distribute engine drive torque to downstream drivetrain components, and a relatively modest fluid volume like 3.75 liters is consistent with a compact, dedicated gearbox rather than a combined transmission-transfer assembly.
  • The service interval for the transferbox fluid is defined as 500 hours or 12 months, whichever comes first. The dual-trigger format — one based on operational hours and one based on calendar time — accounts for machines that may accumulate hours rapidly during harvest seasons as well as those that sit idle for extended periods, where fluid degradation can still occur through moisture absorption and oxidation regardless of use.
  • All six configurations carry the "engine drive" designation in the transferbox note. This indicates the transfer case is mechanically driven directly from the engine rather than from a downstream transmission output, a distinction relevant to understanding fluid shear and thermal load conditions within the unit.
  • The Lexion 7600 and 7700 each appear in two distinct variants within the specifications: one paired with the CS85 threshing system and one with the CS86 under a Tier 3/Stage IIIA emissions classification. Despite the difference in threshing system and emissions standard, both variants share the identical 3.75-liter capacity and 500-hour/12-month change interval, indicating the transfer case specification is not affected by those configuration differences.
  • The Lexion 7500 is listed with a TerraTrac variant alongside the standard configuration, while the 7400 appears without a TerraTrac designation. TerraTrac refers to Claas's tracked undercarriage system, which alters ground contact and weight distribution but does not, according to these specifications, alter the transfer case fluid capacity or service interval.
  • The CS85 and CS86 designations refer to different threshing and separation drum configurations within the Lexion 7000 series. The fact that both share the same transferbox fluid volume and change schedule reflects that the transfer case serves the engine drive function independently of the harvesting system variant installed.
