A new nylon gearwheel has already been made for the Yamaha PW-X and PW-X2 motor, it performs well. Soon it will be sold here.
See the article here.
The nylon gear is a weak part of the Yamaha PW-X / PW-X2 motor. When the motor is broken, it will just be exchanged by Yamaha. Outside the warranty period, this will cost around $750. This is a big problem because, when the gear will be overloaded again, you can keep going this way.
I cannot have the gears injection molded because the numbers are too small, which unfortunately makes production expensive.
Replacement
Remove the broken gear and glue the new one in place. Use common one or two component PU polyurethane adhesive. PU glue has been tested in practice and is very durable.
