38 Olds: Harrison Heater Help

[cron1984]

Good Evening,

Quick thanks to everyone for sharing their knowledge, especially all the guys with threads on their pre-war projects. This forum has been a great source of information and inspiration as I restore my Grandfather’s 38 Olds. 
I’m currently rewiring and cleaning up the Harrison heater. I was able to disassemble and solder new wiring in the blower motor, however the defroster motor is giving me some fits, I can’t seem to get the stator out of the motor housing. The armature spins freely and I can get it to pull out of the brushes, but the stator won’t budge. The plastic plate restricts my vision and I don’t want to force anything and break something. Not sure if the notches in the housing are holding it in there or if it’s just 80+ years of crud. I’ve attached some pictures that will hopefully look familiar to some folks (taped the shaft to keep from losing those washers)
thank you again,

Chris.

Hi cron1984, I'm presently researching all posts about HEATERS, and came across this Post of yours. I recently dismantled a Harrison Heater Motor from likely a late 1930s Chevrolet under dash unit shaped like a triangle on top of a rectangle. I believe it was a 6 volt motor and short. Yours is showing a small Oiling hole on the rear shaft bearing. I had to gut this little motor to get it to move for the display I'm working on. The Non- Brush end of the shaft has a ball shaped bearing that is held in place by a Captive 6 spring finger housing, that hold the ball bearing inside of a FELT Donut soaked in electric motor oil, so when it gets regular servicing of a few drops of this oil motor spins as it should. The 6 spring fingers are made up of 2 sets of 3 fingers each. I imagine when the motor is assembled at the factory it is put on first then the Ball Bearing piece might be press fit onto shaft. As I see it these are not meant to come apart for servicing. Best Wishes to you. Tom

Hi cron1984, As a follow-up, if the shaft spins a little bit, that's good, add a few drops of ELECTRIC MOTOR three in one oil to the Oiling hole at end of housing and put shaft in a hand drill and run it in both directions for a few minuets and that should get you rolling. Sometimes it's best to not try to take everything apart as it could get destroyed it the process. Best Wishes, Tom
