Fendt 800 Vario COM3

Differential fluid capacity & service interval

Fendt 800 Vario COM3 differential fluid capacity is 8,3 liters. Service intervals include checks every 12 months or 500 hours and changes every 1000 hours or 24 months. The data covers 3 configurations.

Additional Notes

  • The Fendt 800 Vario COM3 front limited slip differential holds 8.3 liters across all three listed configurations, covering the 818 Vario, 820 Vario, and 820 Vario GreenTec variants.
  • An 8.3-liter capacity for a front differential is a substantial fill volume, consistent with heavy-duty agricultural axle assemblies that house larger gear sets and limited slip clutch packs requiring adequate fluid immersion.
  • All three configurations share an identical check interval of every 12 months or 500 hours, whichever comes first under normal use conditions.
  • The change interval for the front limited slip differential fluid is set at 1,000 hours or 24 months under normal use, applying equally to the 818 Vario (2007-2009), 820 Vario (2007-2009), and 820 Vario GreenTec (2008-2010).
  • The dual-trigger interval structure, combining an hour-based threshold with a calendar-based one, reflects the variable annual operating hours typical of agricultural equipment, where seasonal use patterns can mean calendar time accumulates faster than engine hours.
  • The 820 Vario GreenTec, introduced from 2008, carries the same 8.3-liter differential capacity and identical service intervals as the standard 820 Vario, indicating no differential specification changes were introduced with the GreenTec designation.
