Additional Notes
- The Peugeot 403 rear differential holds 1.4 liters of fluid, a figure that applies to both the standard and Diesel variants across their respective production years.
- A check interval of 3,000 km is specified for the rear differential under normal use conditions, paired with a change interval of 6,000 km.
- The 403 Diesel, introduced in 1958, carries the same 1.4-liter rear differential capacity as the petrol 403 that debuted in 1955, indicating no mechanical differentiation in the rear axle fluid volume between the two drivetrains.
- The 6,000 km change interval reflects a relatively short service cycle by modern standards, consistent with lubrication technology and engineering tolerances typical of mid-twentieth century rear axle design.
- Both the petrol and Diesel specifications are designated for normal use conditions, meaning the stated 3,000 km check and 6,000 km change intervals are not adjusted for severe or demanding operating environments in the available data.
