Good Morning All,
I've pushed the '63 to the side of the garage for the winter. Snow is on it's way so the garage has to go back to being a garage again. As she is in the midst of a restoration I have decided to work on some "inside" stuff during the winter. First up is the power antenna motor.
I have disassembled it but I see that the negative brush is crimped in. Is there any way to safe un-crimp it without damaging the housing? Brushes are still pretty good and the unit still works ok but since I have it out I figured I would renew it completely.
If anyone that has done it can throw me a bone regarding the negative brush I would forever grateful.
I totally respect the "if it ain't broke don't fix it" stance but this car sat under tress neglected for at least 10 years. I figured as I had to take it out anyways as the mast wouldn't go all the way down that I might as well service it. The brushes were not horrible but they were short. I wanted to replace them and clean and lubricate the whole assembly prior to re installation. This will give me a lifetime of trouble free use.
Either way I have managed to replace both brushes, clean the armature and lubricate the gears. She works like a champ now.
Just to put it out there, while I am out of the antenna mast with cord I do have a good stock of bench tested, working antenna motors for $45 + s/h. If anyone needs just the antenna motor without the mast assembly email me at firstname.lastname@example.org
No need to rewind the armature and fields. They were like new! The commutator was a little "gooped" up from brush dust mixing with the gear lube. All cleaned and running great.
As for brushes I work for a major rebuilder of rotating electrical components (starters, generators, alternators, motors etc.) so I have an endless supply of brushes, bushings etc at my disposal. I just matched up a good 12V set of brushes out of our stock and was ready to roll.
Throwing this out there. If anyone needs components for a rebuild of any of the motors in our cars then let me know and I'll likely have or have access to what's needed.
