Additional Notes

  • The Fiat-Trattori 86 series front differential fluid capacities across the 1994-1996 model range fall into three distinct values: 3.9 liters, 4.0 liters, and 4.1 liters, with one outlier at 5.5 liters for the 50-86V and 50-86VDT variants.
  • The 50-86V and 50-86VDT carry a front differential capacity of 5.5 liters, which is notably higher than every other configuration in the 86 series lineup for the same years, indicating a physically larger front axle housing on those variants.
  • The 55-86V/F, 55-86VDT/FDT, 60-86V/F, 60-86VDT/FDT, and 70-86V/70-86VDT all share an identical front differential capacity of 3.9 liters, suggesting a common front axle assembly across those configurations despite differences in model designation.
  • The F-suffix and FDT-suffix variants — 62-86F, 62-86FDT, 72-86F, 72-86FDT, 82-86F, and 82-86FDT — are each specified at 4.1 liters for the front differential, a value not shared by the V-suffix or LP-suffix variants of comparable models.
  • The LP and LPDT variants, specifically the 72-86LP, 72-86LPDT, 82-86LP, and 82-86LPDT, carry a front differential capacity of 4.0 liters, placing them between the 3.9-liter V-series and the 4.1-liter F-series figures.
  • All configurations across the 1994-1996 range share a uniform fluid check interval of 400 operating hours, regardless of model variant or front axle capacity.
  • The fluid change interval is consistent across all listed configurations at 1,600 operating hours or 24 months, whichever comes first under normal use conditions. The dual-trigger structure means time elapsed can mandate a change even when the hour threshold has not been reached.
  • The DT suffix present in variants such as 50-86VDT, 60-86VDT/FDT, and 82-86LPDT denotes turbocharged engine fitment. All DT and non-DT pairings within the same model share identical front differential capacities and service intervals, indicating the front axle specification is independent of engine aspiration.
