Additional Notes

  • The Morris Cowley 1500 Saloon, Series III carries a rear differential fluid capacity of 1.56 liters, a figure that applies consistently across both the normal use and initial service entries.
  • Under normal use conditions, a fluid level check is scheduled at 1,600 km intervals, while a full fluid change is due at 10,000 km.
  • An initial service change is specified at 800 km, which is a break-in interval designed to flush metal particles generated during the early wear-in period of new gear surfaces.
  • The 800 km initial service change interval is notably shorter than the 10,000 km normal change interval, reflecting the higher contamination rate expected in a freshly assembled differential.
