Additional Notes

  • The Austin 3-Litre, ADO61 rear differential holds 1.42 liters of fluid, a figure consistent with a service fill capacity rather than a full overhaul volume, meaning the housing retains residual fluid during a standard drain and refill procedure.
  • The specified check interval for the rear differential fluid is every 10,000 km or every 6 months, whichever comes first, with both a distance and a time threshold governing the service schedule under normal use conditions.
  • The 6-month time interval runs alongside the 10,000 km distance marker, which reflects a dual-trigger approach where low-mileage operation still requires periodic fluid inspection within a calendar-based window.
