I took this motor apart to paint the outer shells. In the process,the armature came out and now I cannot get it back in place. Any tips on how to re-install the armature and get the brushes back on the commutator? Thanks.

Get three assistants, one to hold each spring loaded brush holder back while you insert the armature. Declare success, open a brown bottle.

That is what I thought but it is really tight quarters and you would have to use something long, thin, and strong to hold back those brushes. To say nothing about my assistants and myself getting in each others way. Will give it a go and see what happens. Thanks for the response.

Frank, I've done small motors like that by using very thin string like dental floss to hold the brushes back while inserting the armature. Just compress the springs and tie the string off, assemble the motor, then cut the strings and pull them out. I don't have a heater motor to look at, but that might work on yours.
All the Best, Chip

Chip, The dental floss was the answer but still no picnic. I spent about six hours playing with brushes and springs getting everything in place to tie them off. Then had a difficulty securing the brushes in the retracted position. There was no good place to hold the brush with the floss. Compound all this with no room for a tool or even your fingers and it tends to turn the air blue with foul language. I also had to worry about getting the floss too secure because I would not be able to remove it when the armature was in place. I am sure you know about all this from your own experience. I finally was able to assemble the motor and remove the floss. This morning I tested the motor and it works! Thank the good Lord. Thanks again for your suggestion. I hope I never have to do this again.
Frank

I'm glad it's done and that it worked out OK. It is tedious stuff. Just think, though: You'll have plenty of heat when you're out driving around this weekend. It will be 92 degrees here, so I'm thinking about the heater, too.
All the Best, Chip

Nice how more modern brush's such as alternator's have a small hole you can use a paper clip to holed them back while installing them...Will have to remember the "floss" method...
