Additional Notes

  • The Maserati Khamsin AM 120 uses a Salisbury-type rear differential across both the standard and limited-slip configurations, with each holding 1.4 liters of fluid.
  • A 1.4-liter capacity in a rear differential of this type is a moderate fill volume, consistent with a compact Salisbury unit designed for a rear-wheel-drive grand touring application.
  • Both the standard and limited-slip rear differential variants share an identical 1.4-liter capacity, meaning the addition of a limited-slip mechanism does not alter the fluid volume requirement for the 4900 engine configuration.
  • Under normal use conditions, the fluid check interval for both rear differential variants is set at every 5,000 km, reflecting a relatively frequent monitoring schedule for a unit of this era.
  • The fluid change interval under normal use conditions is 20,000 km for both the standard and limited-slip Salisbury rear differentials, placing the drain-and-refill cycle at four times the length of the check interval.
  • The limited-slip differential variant carries a distinct designation in the specifications, indicating that while capacity and intervals are shared with the open differential, the two units are treated as separate service entries for the 1974-1982 Khamsin 4900.
