Additional Notes
- The Daihatsu Charmant rear differential holds a capacity of 1 liter across all three configurations covered in the 1981-1987 specifications, spanning both the 1300 and 1600 engine variants.
- A 1-liter differential capacity is consistent with compact rear-axle housings typical of small sedans from the early 1980s, where the differential unit is relatively modest in size compared to larger rear-wheel-drive platforms.
- The check interval for the rear differential fluid is set at 10,000 km or 6 months under normal use conditions, whichever comes first, applying equally to the 1300 and both 1600 production spans.
- The fluid change interval is specified at 40,000 km or 24 months under normal use conditions, meaning the fluid is changed at a frequency four times longer than the check interval on a distance basis.
- The 1600 engine variant is represented by two separate specification rows: one covering 1981-1983 and another covering 1983-1987, while the 1300 variant is covered by a single row spanning the full 1981-1987 range.
- Despite the 1600 variant being split across two production periods, both rows carry identical capacity and interval figures, indicating no revision to the rear differential service specifications between those periods.
