Motor component removal
 

I really would like to start winding motors...I have done the spinbrush swap (not a hybrid, RS endcap to SB can with white motors crown (9? i forget) and white pinion gear). I know how the motors basically work, but I want to start taking them apart and winding them myself. The only thing is that I can't manage to start disassembling them without damaging them. To just get the crown gear off I have to take the end cap off then give the drive shaft a few taps with a hammer to allow the pinion puller to get behind the gear. I would like to know how to get all the componenets out of the motor without damaging any...I have found there are several rings that hold the motor together but beyond that I can only get it apart with a few taps with a hammer and I know it screws up the motors alignment with the magnets and such. My dad is an electrical engineer and I know he is a master in all the properties of electronics and I know me and him can make an ultimate motor (along with a FET mod) if I could just get these motors apart.

Proper tooling is the answer to your question.

The endcap is easy enough to get out with a small screwdriver. No biggy. Its the armature that gives people problems. Remove them with a good pinion puller such as the GWS GP Pinion Gear Puller Set. Which youc an find at Balsa Products Hobby Supply Web Site - just do a search on Yahoo for the website URL. You can order BB cans, carbon brushes, and magnets at places like DinBall(RCMart) online.

I have the pinion puller, but in order to get the holding apparatus under the crown gear I have to take off the endcap and tap the shaft to give me some room to get the pinion out. And after i hammer it know I Have screwed up the motor. So any suggestions on how to take it apart piece by piece from the inside/back?

In the Xmod Science forum there is a thread on removing magnets with the armature still in place...

You can't really take the armature out of the Xmod without taking the pinion off though.

You don't have to use up that much room to get the pinion puller under the pinion, it shouldn't ruin your armature.
