AMERICAN FLYER PREWAR 3020

There are a couple of options here.  If you have a later junker Flyer engine with the tube brushes, you can swap the bracket that has the tube brushes and go that route.  That is the easiest method.

Otherwise, I have had some luck with removing the old brush from the metal tab, making sure to leave the round hole in the tab that holds the brush in place, filing a new brush down so that the end fits into the hole and then using super glue to hold the brush in place, making sure not to completely cover the brush in super glue (ie making sure that you still have an electrical contact), and trimming the length of the brush, as the modern brushes are a bit too long for the tabs that hold it against the armature.

You can solder new brushes on the finger, but there is a 50% they will shatter form the heat. NWLs idea is better IMO.

Wonder how AF accomplished this without shattering them?

Thanks for your reply.

Thanks to the O Gauge Forum "Brain Trust" for your suggestions and ideas!

The original brushes  were not soldered in, they were pressed in.  The original brushes appear to be strands of copper that were formed into a larger round brush.  The modern replacement brushes are carbon.

Good to know, Thank You for your time!
