How to re install motor brushes on a DC Motor ( Currie Ebike ) same for all DC Motors

This is a quick video for a subscriber how to get the motor brushes to go back in a 24 volt Ebike DC MOTOR , made by a company called CURRIE MOTORS, I found it very tricky but then I noticed something :)
Hope you can get it fixed using this technique.
