Coded TR3, this 1972 racer shares its factory manual with the TD3. The part number for both is LIT-11623-29-00.
The two machines were developed side by side, and the book treats them that way. Procedures written for one carry notes where the other differs, which is how a period race shop would have wanted it when both bikes were in the same workshop.
Content is what Yamaha issued at the time: assembly and disassembly sequences, specified torques, clearance and service limits, wiring, and fault-finding. Nothing about it is aimed at a casual reader.
If you already hold a TD3 manual, compare part numbers before buying, because it will be this same volume. Otherwise, confirm TR3 on the machine and LIT-11623-29-00 on the book.
