Wow... it really can be hard for the non-experienced, although it is really mostly a
mechanical grasping!
I used to rewind tons of motors, as I had no choice when working in the bush many years ago!! ...
If it is 4 pole, and has a total of 36 slots, then that's 9 slots per pole. So you 'should' find that each 'pole' would
have so many turns looping around say slots 1 to 9, which then connect with the same wire to so many turns
looping around slots 2 to 8, and so forth for slots 3 to 7, 4 to 6, for example. These groups of coils are made
typically on a layered wooden rectangular plywood 'former'...
You then knock out the wooden/plastic bits covering each slots coils, and keep them for re-use.
Chop the windings off at one end, and count the turns, and knock the windings out of the slot tunnels.
When the new windings are loose & unvarnished, you can 'jiggle' them into the slots/cavities, before using an
insulating material like 'ElephantHide' to slide on top, before knocking in the top 'wooden' saved pieces.
Later, varnishing will hold all the coils together properly, so there is no magnetic vibration. Connect the coil
ends as per the observations during dis-assembly. I don't know what more to say!!
It's do-able, but not for the feint hearted... Good luck !
