Does anyone have info about rebuilding the motors on the 646? I am certain the motors can be rebuilt. They're just electric motors.

I have Googled around trying to find info about doing it and came up empty. There are companies that will do it. But I don't want to send it across the country, pay hundreds and wait 3-4 weeks. I have friends that could do it if the instructions were available.

Any info would be greatly appreciated!
