Funny thing about this thread, i just took apart the blower motor for my 67 barracuda for restoration. Leece Neville type. These use oilite bronse bushings. A couple drops of 30 weight motor oil works just fine for this.
If dissassembling to clean up i recommend turning the armature brush contact surface to remove grooving, and carefully file the carbon brushes with 600 grit to smooth them.
I cleaned my armature by putting thin tape on the shaft to protect it, and installing it in a drill chuck, and putting the drill in my vise. While spinning the armature use a flat popsicle stick with 600 grit sandpaper to smooth out the brush contacts.
The small drill hole on the endcap is a great idea for non restored drivers.
