Claas Lexion 8000

Differential fluid capacity & service interval

Claas Lexion 8000 differential fluid capacity ranges from 9,6 to 11,4 liters. Service intervals require changes every 500 hours or 12 months. The data covers 5 configurations.

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

Additional Notes

  • The Claas Lexion 8000 series rear differential carries two distinct capacity figures depending on the part number group: 11.4 liters for assemblies identified by part numbers 1499/303 and 1499/302, and 9.6 liters for assemblies identified by 1499/311 and 1499/310.
  • The difference between 11.4 liters and 9.6 liters across the two part number groups represents a variation of 1.8 liters, which is meaningful when filling to the correct service level, as underfilling or overfilling a differential can affect lubrication film integrity and heat dissipation.
  • Under normal use conditions, the rear differential fluid change interval is set at 500 hours or 12 months, whichever comes first, applying a dual-trigger structure that accounts for both operational intensity and time-based fluid degradation.
  • The 500-hour or 12-month interval is consistent across all five configurations covered in the 2021 specifications, spanning the Lexion 8700, 8800, and 8900 variants in both standard and TerraTrac configurations.
  • Tier 3/Stage IIIA emissions-rated variants of the Lexion 8700 and 8800 share identical rear differential capacity values and change intervals with their non-Tier 3 counterparts, indicating the emissions classification does not alter the differential service specification.
  • The TerraTrac designation refers to a tracked undercarriage configuration, and the rear differential capacity and interval specifications for TerraTrac-equipped machines are listed identically to wheeled variants within the same model designations.
