need 6 volt heater motor brushes or replacement motor

imported_rlcokc · November 29th, 2007

Have 41 Firetruck with a 6 volt Ford 2 speed heater. Brushes shot and need new brushes or motor for replacement. Can't find either as brushes too small and 6 volt motors not locally available. Anyone have suggestion? Thanks

Not sure where you looked but my local hardware store has a nice selection of small motor brushes. Any motor repair shop would have large assortment. Also you only have to get close. Over sized brushes are very easily cut to size by sanding with coarse paper on a flat surface....Bob

Rod, you should be able to find brushes through a motor rebuilder in your area. You may have to get slightly larger ones and file/sand them to size. Also, Grainger electric supply http://www.grainger.com has one 6 volt motor in their catalog and it fits perfect into the cradle of a 1930's vintage heater. RPM is right for fan application. They also sell a 4 or 5 bladed fan

Need to be a bit careful on replacing the motor with another as the speed is very important. The load due to a fan goes up by the cube of the change in speed. If at all possible try to replace the brushes-the commutator will probably need to be smoothed up in a lath. Then clean the slots out on the comm to insure no segements are shorted.
