How to open a CM36 motor?
I'm trying to mount a castle creations CM36-s5700 motor but I'm having problems because I can't find a position where the little screw heads are not fouling anything.
I want to take the front cover off to either close it with a different offset between the little screws and the motor mounting screw holes or, if that won't work, to tap new motor mounting screw holes into it. I removed the 3 front screws hoping that the front cover will drop out but it didn't. I applied moderate force to it but it didn't budge. Does anyone know how to remove it? Thanks, Avner. |

I have always removed the screws then tapped the spindle on my work bench until it pops out. The stick a screw driver through the motor wedged into the bearing and tap the other side out. I done that to put ceramic bearings in several.

DickyT,
I'm not sure I understand you. Do you first remove the rear cover by tapping on the rotor and then remove the front cover by tapping on the bearing from inside the can? Thanks, Avner. |
When I opened my 4600 for bearing replacement I did the following and it worked very well.
Removed the small screws from the can that hold the pinion end endplate. Placed a small flat blade screwdriver on the inside edge of endplate where the wire opening is. Have the screwdriver laid down toward can as much as possible and pointing in the direction of the pinion, lightly tap the screwdriver. Once endplate moves enough to place the small screwdriver in between the endplate and can, insert screwdriver and gently twist, slowly work your way around the can twisting gently. Be careful not to bend the can. I did not remove the opposite endplate. I peeled the sticker back (no need to fully remove sticker)and removed the bearing with the endplate and can still assembled. |

Then stick a screwdriver though the motor, being careful not to damage the copper windings. from the side you just removed and do the same to pop off the front. I use the word tap literally. no need to pound, just tap a few time. pounding could damage the magnets on the rotor. The first time tyou do this to the motor it will require more force than any following attempts. |
Ok, I guess they aren't glued. My bad.

I would not recommend opening these motors if possible. I opened mine to clean it, but breaking the glue bond made the motor weak. after just a couple big jumps the motor pulled away from the front motor plate. I redrilled the holes and the same thing happen again. I was very unhappy, I'm going to return the motor, but will not open another one of these motors again.
