Additional Notes

  • The JCB JS-110W Hydradig transfer case holds 1 liter of fluid across both the Stage IIIB/T4i and Stage IV/T4f engine configurations, placing fill volume in a range typical of compact auxiliary driveline units rather than primary axle or transmission assemblies.
  • The Stage IIIB/T4i configuration carries a transfer case check interval of every 6 months or 500 hours under normal use conditions, whichever comes first.
  • The Stage IV/T4f configuration shortens the transfer case check interval to every 3 months or 500 hours under normal use conditions, cutting the calendar-based check frequency in half compared to the Stage IIIB/T4i variant.
  • The fluid change interval for the Stage IIIB/T4i transfer case is set at 12 months or 1,000 hours under normal use conditions.
  • The Stage IV/T4f configuration reduces the transfer case fluid change interval to 6 months or 1,000 hours under normal use conditions, meaning the calendar-based drain period is half that of the Stage IIIB/T4i specification despite the hourly threshold remaining identical at 1,000 hours.
