Engine service manual

It’s been a while since I last added a new manual to the site. Today’s manual cover engine service. The manual itself was made for Yamaha retailers and mechanical workshops so it covers more advanced methods that the regular service guides.

We get a lot of emails with questions about crankshaft assembly, hopefully this will be able to help with those questions and a lot more. The manual is quite early, from 1965 so it covers specifics about older models, in particular the YG1, the YJ1, the YA6 and the YDS3. The methods used work for later models too. Anyway, go to the manuals section or click the link below to view the manual, as always: right click and select save link as… to download an offline version.
