Yamaha YP30NT Service and Repair Manual

One book, two machines: Yamaha's LIT-19616-00-07 serves the YP30NT and the YP20NT. This listing is for the YP30NT, whose code is stamped on the unit.

The manual is organised so shared procedures appear once and size-specific values appear separately, which keeps the specifications honest. Expect torque figures, service limits, clearance values and adjustment settings, all as Yamaha published them.

Beyond the mechanical sections there are complete electrical diagrams and a fault-finding sequence that begins with what the operator observed and narrows from there, which keeps a diagnosis from turning into a series of parts swaps. Maintenance intervals come from the factory schedule and are listed by hours rather than left to habit.

Read YP30NT off the machine and check it against the coverage before ordering. The two sizes in this book do not share every specification, and the code is the only thing that tells you which column to read.
