Additional Notes

  • Across all three engine variants of the Maserati Indy AM116 — the 4200, 4700, and 4900 — the rear Salisbury differential holds a capacity of 1.4 liters, a figure that applies equally to both the open and limited-slip versions of the unit.
  • The 1.4-liter fill capacity is consistent whether the differential is a standard open type or a limited-slip unit, meaning the two configurations share identical fluid volume requirements despite their mechanical differences.
  • Under normal use conditions, a fluid level check is specified at every 10,000 km across all six configurations covered in the specifications.
  • The fluid change interval under normal use conditions is set at 20,000 km, which applies uniformly to every Salisbury differential variant listed, regardless of engine displacement or limited-slip fitment.
  • The Indy 4200 (AM116) covers the widest model year span in the specifications, running from 1969-1974, while the 4700 (AM116/47) spans 1970-1974 and the 4900 (AM116/49) spans 1973-1974.
  • The 4900 variant (AM116/49) shares the same 1.4-liter differential capacity and the same 10,000 km check and 20,000 km change intervals as the earlier 4200 and 4700 variants, despite entering the lineup later in 1973.
