Installation
Install the regulator / rectifier in the reverse order of removal. Pay attention to the following points:

Confirm the regulator / rectifier parts number and ID mark before installing.
For 32800-47810-RX0 (made by Shindengen), use 2 pcs of Bolt included in the Rectifier
set to install because height of the rectifier mounting is lower than the original one.
Be sure to install it properly according to the illustration below.

torque.
