Frequently Asked Questions
What chassis and body styles does this manual cover?
The manual covers all S102A, S124A, and S129A chassis codes, spanning coupe, sedan, and wagon body styles produced from 1971 through 1978, including the performance-oriented RX-3 SP variant with its upgraded suspension tune.
Is the Mazda Savanna the same as the RX-3?
Yes. The Mazda Savanna was the Japanese domestic market badge twin of the RX-3, sharing identical mechanical specifications. The Grand Familia rotary variant is also mechanically related. This manual’s procedures apply directly to those models.
Does the manual explain rotary-specific service like apex seal replacement?
Absolutely. The manual dedicates detailed sections to Wankel-specific components including apex seals, side seals, corner seals, rotor housings, and eccentric shaft service — procedures not found in conventional piston-engine manuals.

The manual is a PDF file, compatible with Windows, Mac, Linux, Android, and iOS devices. After purchase you can download it immediately and re-download it at any time. Individual pages or full sections can be printed for bench use.
