best procedure to replace the M3 run motor

[solst1ce]

This 1956 M3 is my first hammond and I've had it for a couple weeks. It was pretty well frozen up when I got it, but a few days after oiling and rotating the TG spindle I got it working pretty well.
Unfortunately after a few days of playing well, the RUN motor stopped motivating after releasing the START motor and would gradually slow to a stop. I tested my weak RUN motor and it is clear that one of the coils is open. I have ordered a replacement motor but can't seem to find a video or 'step by step' explanation of how one goes about doing the replacement. Any and all advice would be very helpful to this Hammond newbie- please and thanks!
P.S. are there parts available to refurbish the damaged motor... I wouldn't mind keeping a working spare in case I have a problem in the future.

This video is for the total disassembly and cleaning of the scanner and also has instruction for removing/reassembling the motor.

Thanks so much...that is just what I needed to see and the some!

What you would need is a new coil. I am in the process of getting a batch of coils wound to repair run motors. This especially makes sense for the rare 230V/50Hz run motors. I think it would not really make sense for the 115V/60Hz motors as spare motors are readily available and just buying a spare is much cheaper than someone pay for the work to repair it.

Your skill level at moment is "how do I get the run motor out". Disassembling and reassembling a run motor is really many levels higher. You need several special tools for a proper job.

PS: If you want to get rid of your dead run motor, I would be interested in getting it, as I am doing some experiments now to get the coils reproduced for these motors.
