Additional Notes

  • The rear Salisbury differential across both the 4200 and 4900 engine variants of the Maserati Quattroporte III, AM 330 carries a fluid capacity of 1.4 liters, a figure that applies equally to the standard and limited-slip configurations.
  • Under normal use conditions, the rear differential fluid on the 4200 (1979-1983) is subject to a check interval of every 5,000 km and a change interval of every 20,000 km.
  • A first-change-only interval of 2,000 km is specified for the rear differential on the 4200 (1979-1983), reflecting the common practice of flushing break-in debris from a newly run differential before returning to the standard service schedule.
  • The limited-slip rear differential on the 4200 (1979-1983) shares the same 1.4-liter capacity and identical check and change intervals as the standard open differential, with the 5,000 km check and 20,000 km change applying under normal use.
  • The limited-slip rear differential on the 4200 (1979-1983) also carries the same 2,000 km first-change-only interval as the standard unit, indicating a uniform break-in service requirement regardless of differential type.
  • The Quattroporte 4900 (1979-1986) rear Salisbury differential maintains the same 1.4-liter fluid capacity as the 4200, with normal-use intervals of a 5,000 km check and a 20,000 km change.
  • The first-change-only interval of 2,000 km on the 4900 (1979-1986) rear differential mirrors the specification seen on the 4200, applying to both the standard and limited-slip Salisbury units.
  • The limited-slip rear differential on the 4900 (1979-1986) retains the 1.4-liter capacity and the 5,000 km check plus 20,000 km change schedule under normal use conditions, consistent with the other configurations across the model range.
