Unfortunately you need to replace the whole unit 48090-50090. It costs nearly $1000 here in Japan. Another idea might be to change to spring suspentions.

You will know more seeing the chart below although it's from a Denso's 130A generator. The top horizontal scale is 200A. Due to the pulley's diameter the rpm is higher than the engine's.
