Model code RT3, part number LIT-11613-08-01. That is the 1971 RT3 and the Yamaha manual written for it.
Like the other books of its period, this one covers a family: the 1971, 1972 and 1973 model years, and the DT1, DT2, DT3, RT1 and RT2 in addition to the RT3. Yamaha saw no reason to publish six near-identical volumes, and the result is a reference that shows the relationships between these machines rather than hiding them.
You get sequenced disassembly and reassembly, inspection criteria, tightening torques, clearances and service limits, wiring diagrams and fault-finding guidance, written in the factory's own plain technical register.
Confirm the RT3 code against the frame before ordering. Decades of rebuilds mean the badge on the tank is not always the last word on what you are working on.
