Additional Notes
- The Austin A35 rear differential holds 1 liter of fluid across both the 1956-1962 and 1962-1968 configurations, a figure consistent with the compact final drive units found in small British cars of that era.
- A 1-liter capacity in a rear differential of this class typically reflects a relatively small, integrated axle housing rather than a separate carrier assembly, meaning the entire fluid volume serves both lubrication and heat dissipation within a confined space.
- The check interval for the rear differential is set at 1500 km under normal use conditions, applying equally to the 1956-1962 and 1962-1968 variants.
- A 1500 km check interval is notably short by modern standards and reflects the maintenance expectations common to vehicles of mid-20th century design, where more frequent inspection was standard practice.
- The fluid change interval is specified at 9000 km under normal use conditions, a figure that holds across both the 1956-1962 and 1962-1968 rear differential entries.
- The ratio between the check interval (1500 km) and the change interval (9000 km) is exactly 1:6, meaning six checks are called for within each full drain-and-refill cycle under normal use conditions.
