Claas Ares 800

Differential fluid capacity & service interval

Claas Ares 800 differential fluid capacity ranges from 5,5 to 6 liters. Service intervals include checks at 300 hours and changes at 1200 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 Claas Ares 800 series front differential specifications list two distinct capacity values across all three variants: 6 liters and 5.5 liters. In differential service contexts, differing fill capacities for the same application typically reflect different axle configurations or housing sizes installed on the same model line.
  • The Ares 816 (H4412) front differential carries a capacity of either 6 liters or 5.5 liters depending on the specific axle fitted, with both figures applying to the 2002-2007 production span under normal use conditions.
  • The Ares 826 (H4422) front differential shares the same dual-capacity pattern as the 816, with 6 liters and 5.5 liters listed as separate entries for normal use across the same 2002-2007 period.
  • The Ares 836 (H4432) front differential likewise carries capacity specifications of 6 liters and 5.5 liters, maintaining the same split seen across the other variants in the 800 series for 2002-2007.
  • A fluid level check interval of 300 hours is specified for the front differential across all three variants, the Ares 816, 826, and 836, under normal use conditions. In agricultural equipment service, a 300-hour check interval is a relatively frequent inspection point, reflecting the mechanical demands placed on front axle differentials in field operation.
  • The fluid change interval for the front differential on all three variants is set at 1200 hours or 12 months, whichever comes first, under normal use conditions. The dual-trigger format, combining an hourly threshold with a calendar limit, accounts for machines that accumulate hours slowly and would otherwise go extended calendar periods without a fluid change.
  • The ratio between the check interval and the change interval across all listed variants is 1:4, meaning four inspection cycles occur for every one fluid change cycle. This structure allows for monitoring of fluid condition and level between full service events without requiring a drain and refill at each check.
