Additional Notes

  • The Reform Muli 440 carries the smallest rear differential capacity in the lineup at 3 liters, while the Muli 550 and 560 both specify 5 liters, reflecting the larger drivetrain housings in the higher-numbered variants.
  • Across the Muli 660 and 770 variants, the standard rear differential holds 5.5 liters, whereas the limited slip version of the same differential is specified at 5 liters. The 0.5-liter reduction in the limited slip configuration is consistent across both the Kubota and Peugeot engine variants of those models.
  • The Muli 440, 550, and 560 share a fluid change interval of 600 hours or 24 months under normal use conditions. The 660 and 770 variants, regardless of engine type or differential configuration, specify a longer calendar interval of 600 hours or 36 months.
  • All models across the 1992-2000 range share a fluid check interval of 200 hours under normal use conditions, meaning inspection occurs three times before each scheduled fluid change at 600 hours.
  • The Muli 660 is available with either a Kubota or Peugeot engine, and both engine variants carry identical rear differential capacities: 5.5 liters for the standard differential and 5 liters for the limited slip unit. The same pattern applies to the Muli 770.
  • The 600-hour change interval is an operating-hours-based threshold common in agricultural and utility machinery, where annual mileage is not a meaningful measure and engine hours serve as the primary indicator of mechanical wear and fluid degradation.
  • Limited slip differentials require fluid formulated to manage the friction characteristics of the clutch packs or friction plates inside the unit. The separate capacity specification for limited slip variants on the Muli 660 and 770 reflects a physically distinct internal configuration from the open differential.
