Race machinery got thin documentation, and what exists is worth having. LIT-11623-29-00 is Yamaha's manual for the 1972 TD3, and the same book covers the TR3.
The code on the machine is TD3. Confirm it, because the two models were built in parallel and the book addresses them together rather than separately.
Also covered
- TR3, same model year
Content follows the factory pattern of the period: assembly and disassembly in sequence, specified torques, clearances and service limits, wiring, and fault-finding. For a bike that was sold to be raced and rebuilt often, the tolerance figures are the part that still gets used today.
Quote LIT-11623-29-00 if you are checking against paperwork you already hold.
Little of this material was reprinted afterwards, so the original part number is the one to chase.
