Yamaha's LIT-19616-00-34 documents both the YT5700P and the YT6700P. This page covers the YT5700P, whose code is on the machine itself.
Since the two models are built on common architecture, one manual made sense, and the text marks the places where the specifications part company. Torque values, clearances, wear limits and adjustment settings are all given as factory figures.
Procedures are written in working order — inspect, remove, measure, decide, reassemble — with the cautions placed where they matter. Electrical coverage is by diagram, and the troubleshooting section starts from the symptom.
Maintenance intervals are the factory ones, and the routine items are listed with the quantities and grades Yamaha specified.
Match YT5700P against the plate on your unit before ordering; the sibling model uses different figures in several places, and working from the wrong column is the usual way a straightforward job turns into a long one.
