Additional Notes

  • All eight configurations across the Fendt 800 Vario S4 range — covering the 822, 824, 826, and 828 variants — share an identical front limited slip differential fluid capacity of 9 liters, indicating a uniform axle housing design across the lineup.
  • The 9-liter capacity figure represents a service fill volume, which is the amount of fluid required when refilling a drained but otherwise intact differential, rather than a dry or overhaul fill that would account for additional fluid retained in passages and coolers.
  • A limited slip differential requires fluid specifically formulated to interact with the friction clutch packs inside the unit. Using an incorrect fluid type can alter clutch behavior and affect torque distribution between the front wheels.
  • The fluid check interval is set at 12 months or 500 hours under normal use conditions, whichever comes first. The dual-trigger format means high-utilization machines will reach the 500-hour threshold well before the calendar year expires.
  • The fluid change interval is 1000 hours or 24 months under normal use conditions. At this interval, the elapsed time limit doubles the check interval while the hour-based limit also doubles, maintaining a consistent 2:1 ratio between check and change schedules.
  • Each model variant appears in two serial number ranges: a sequence starting at 0101 with a 2016 start year, and a separate sequence starting at 00F05001 with a 2018 start year. Both serial ranges carry identical capacity and interval specifications for the front limited slip differential.
  • The split into two serial number bands per model — rather than a single continuous range — reflects a mid-production serial numbering change beginning with units produced from 2018 onward, while the underlying differential service requirements remained unchanged across that transition.
