Additional Notes

  • The Maserati Mexico AM 112 power steering system carries a 2-liter fluid capacity across all listed configurations, which is a relatively substantial reservoir volume for a grand touring car of the era and reflects the demands of a hydraulic assist system designed to manage the weight of a large-displacement front engine.
  • Alongside the 2-liter power steering reservoir, each configuration also specifies a separate steering box capacity of 0.2 liter, indicating a distinct lubrication point that requires independent servicing from the main hydraulic circuit.
  • Both the power steering reservoir and the steering box share identical service intervals under normal use conditions: a fluid level check every 5,000 km and a full fluid change every 20,000 km.
  • The Mexico 4200 AM 112 covers the 1969-1972 production span, while the Mexico 4700 AM 112/1 appears across two separate date groupings: 1964-1967 and 1968-1972, with both groupings carrying the same 2-liter and 0.2-liter capacity figures.
  • The 0.2-liter steering box capacity is notably small, representing roughly one-tenth of the power steering reservoir volume, which is consistent with a recirculating-ball or worm-and-sector steering box that relies on a contained gear oil fill rather than a pressurized fluid circuit.
  • All six specification rows are designated for normal use conditions, meaning the 5,000 km check and 20,000 km change intervals are not adjusted for any severe-duty operating scenario within the listed data.
  • The capacity figures for both the power steering and steering box remain unchanged between the Mexico 4200 and Mexico 4700 variants, despite the two models using different engine displacements, suggesting the steering hardware shared common specifications across the AM 112 family.
