Blower Motor Brushes
Took apart my '55 Olds blower motor to replace the primary lead wire and to do a general clean up / paint.
Upon removing the armature/shaft, the spring loaded brushes ("P" stamp in the photo) popped out - how in the heck am I going to reassemble this thing - someone had to assemble this thing to begin with - what do you do to retain those brushes to reinsert the shaft through that collar?
Ugh

that's gonna take some creativity...
drill a couple of very small holes in the proper places so you can push the brushes into their holders, then put a small brad through each hole to hold the brushes in place, then reassemble the motor and remove the brads.
just a thought.

They were clearly assembled by magic! I was thinking "ship in a bottle" trick like rigging the brushes back into the holders with a dental floss wrapped band and as the commutator is moved into position, slip the string retainer out. The brushes pop back into their happy place.

Isn't this where the manual says for assembly- reverse procedure. I use paper clips bent to hold the brush wire back. Then bend the wire over the end cap to stay in place. As soon as the brushes begin to go over the commutator, remove the paper clips. If this isn't able to work you may need to take the armature out and assemble the brush cap over the armature and then replace the armature and brushes as a complete assembly. Take your time and have patients. As far as magic goes there is a combination of swear words that seems to work well, but that is a trade secret.

Not yet - although I've tried quite a few so far...I'll let you know when (if) I get it figured out...there is an armature shop the next town over, so that is my ace up the sleeve...

SUCCESS!
I ended up drilling two small holes in the top of the housing and running a paperclip through it to retain the brushes.
The holes will be hidden by the blower 'squirrel cage' and housing so no worries there.
I bench tested before I continue just to be sure.
My advice if you do this, don't paint the housing before you do it.
