Fendt 700 Vario COM3b

Additional Notes

• Across the Fendt 700 Vario COM3b range covered here, the front limited slip differential fluid capacity falls into one of two values depending on the variant. The 714, 716, 718, and 720 Vario models each hold 8.3 liters, while the 722 and 724 Vario models hold 9.2 liters. The higher capacity in the upper variants reflects a physically larger differential housing suited to the greater torque loads of those models.
• The 8.3-liter figure applies uniformly across four model variants — the 714, 716, 718, and 720 Vario — spanning serial number prefixes 732 through 735. A consistent capacity across multiple variants in a range typically indicates a shared axle or differential assembly rather than model-specific hardware.
• The 9.2-liter capacity shared by the 722 and 724 Vario (serial prefixes 736 and 737) represents a roughly 11 percent increase over the 8.3-liter figure. In differential service contexts, a larger fluid volume generally supports greater heat dissipation and lubricant longevity under sustained load.
• All twelve rows carry an initial service interval of 50 hours, regardless of variant or capacity. An early fluid change at 50 hours is standard practice for new or rebuilt differentials, as metal-to-metal break-in contact introduces fine metallic particles into the oil that are best removed before normal service intervals begin.
• Under normal use conditions, the check interval for all variants is set at 12 months or 500 hours, whichever comes first. The dual-trigger format — combining a calendar period with an operating hour threshold — accounts for machines that may accumulate hours quickly in seasonal agricultural work as well as those used more intermittently.
• The normal-use change interval across all variants is 1000 hours or 24 months. Pairing a 500-hour check with a 1000-hour change means the fluid is inspected at the midpoint of the change cycle, allowing early detection of contamination or degradation before the full interval is reached.
• The limited slip designation noted for all front differentials in these specifications indicates a friction-based torque-biasing mechanism. Limited slip differentials require fluid specifically formulated to work with friction modifiers, as standard gear oils can cause chatter or premature wear in the clutch packs that provide the locking action.
• The initial service row for each variant lists only a change interval at 50 hours, with no check interval specified. Under normal use, a check at 12 months or 500 hours is listed separately. The absence of a check step in the initial service row reflects that the 50-hour first change itself serves as the inspection event for a newly filled differential.
