Additional Notes

  • The front differential fluid capacity across all Fendt 300 Vario S4 variants covered here is 7.7 liters. This figure applies uniformly to the 309, 310, 311, 312, and 313 Vario models in both Power and Profi trim levels for the 2015-2021 period.
  • A 7.7-liter service fill capacity is consistent with a standard drain-and-refill procedure rather than a full overhaul fill, where additional volume would typically be required to account for residual fluid in associated passages and components.
  • Under normal use conditions, the front differential fluid change interval is set at 1,000 hours or 24 months, whichever comes first. The dual-trigger structure means calendar time and operational hours are treated as equally valid thresholds.
  • A fluid level check is also specified under normal use at 12 months or 500 hours. At that interval, no fluid change is required, only a condition and level inspection, placing the check at roughly the midpoint between drain intervals.
  • A first-change-only interval of 50 hours is specified separately from the normal service schedule. At 50 hours of operation, a one-time early drain is called for across all 309-313 Vario Power and Profi variants. Early drain intervals of this type are standard practice for new or rebuilt differentials, as initial break-in generates fine metallic particles that are removed before the regular long-interval schedule begins.
  • The Power and Profi trim designations within each model number carry distinct serial number prefixes, for example 346/23/0101 for the 309 Vario Power versus 346/21/0101 for the 309 Vario Profi, yet both share identical front differential fluid capacities and service intervals.
  • The same pattern of trim-level serial number differentiation and identical fluid specifications repeats across the 310, 311, 312, and 313 Vario variants, with Power variants carrying the /23/ infix and Profi variants carrying the /21/ infix in their serial number codes.
