Additional Notes

  • The rear differential on the Morris Isis Series II carries a fluid capacity of 2.13 liters, which applies uniformly across both the Saloon and Traveller body styles for the 1956-1958 production span.
  • Under normal use conditions, the rear differential fluid is subject to a check interval of 1,600 km, reflecting a relatively short inspection cycle consistent with maintenance practices of mid-1950s vehicles.
  • The normal-use change interval for the rear differential fluid is set at 10,000 km, applying equally to both the Isis Saloon and Isis Traveller, Series II.
  • An initial service change interval of 800 km is specified for the rear differential on both body styles, a notably shorter interval than the standard 10,000 km cycle associated with normal use.
  • The initial service entry carries no check interval, only a fluid change at 800 km, whereas the normal use condition includes both a check at 1,600 km and a change at 10,000 km.
