Additional Notes
- The Fendt 800 Vario COM3b front limited slip differential carries a capacity range of 9-11 liters across all five variants covered by the 2011-2016 specifications, spanning the 819, 822, 824, 826, and 828 Vario models.
- A capacity expressed as a range rather than a fixed value, such as 9-11 liters, typically reflects acceptable fill variation due to factors like operating temperature at the time of service or minor manufacturing tolerances within the differential housing.
- The check interval is set at 12 months or 500 hours, whichever comes first, meaning fluid condition and level are assessed on a relatively frequent basis relative to the full drain cycle.
- The change interval is specified at 1000 hours or 24 months, placing the drain-and-refill service at exactly double the check interval in both time and hours, which reflects a structured two-stage maintenance approach.
- All five model variants share identical capacity, check, and change specifications under normal use conditions, indicating no differentiation in front differential service requirements across the 819-828 power range within the COM3b generation.
- The normal use condition designation applies uniformly across the 819, 822, 824, 826, and 828 Vario Stage IIIb / EPA 4i configurations, meaning the 9-11 liter capacity and the 1000-hour or 24-month change interval are tied specifically to standard operating conditions rather than a more demanding duty cycle.
