Forty something Arvin auto heater

OK, I bought this heater on line for my 39 Studebaker. Turns out it was built in Colombus In. heh!

I would like to pull the fan blade off the motor shaft so I can service the motor. I don't see how its held on. looks like it must be pressed on. Anybody familiar with this ancient technology?

Its a great looking art deco design with a little red fan speed knob which lights up when the fan is on.

Tom, my 39 buick had two separate 6v motors. One for general heat and one for the defrosters. Both in the same under dash enclosure.

So I wired them in series to use on 12 volt system. Basically for the few times I needed the windshield cleared of moisture or needed a little heat. Depending on your heater you may want to substitute a 12 volt motor. That's if it is a single motor unit.

You are also doing so much you will probably put in a new electrical fuse box. Cars before the fifties did not fuse everything like they did in later years..

There are little converters one can use for converting 12 to 6 volts. It is a single motor design.

Quite a current is drawn by those motors. Hard to drop 12 down to six volts without being wasteful at those type of current draws.

Any form of 12 to 6 volt converters in that current range may be expensive as well. Although a string of cheap fifty amp diodes would do it but they will generate some heat. Yet still very cheap and will work well.

I might identify the motors frame number and see if I could find a twelve volt motor. With the same motor frame type as a reasonable alternative.
At least have a friend or yourself do a current draw check at six volts to find the actual draw of that motor.

The rheostat fan speed control burst into flame on my 1954 Plymouth a lot of years ago while I was driving along. I pulled over beside a mud puddle and the two young ladies in the front seat with me jumped out of the car into the mud with their high heel shoes on. I had turned the control off by then and the flames where gone but there still was some residual smoke. I guess from the female perspective the girls though the car was going to explode or self incinerate.

I suspect without knowing that most 12-6 volt decent switching type converters are not easily found or cheap at the current range heater motors draw. Not a big issue in context but just a detail. The heater box below the dash on the firewall seems to not interfere with anything in my case either.

Apparently I need to do some more homework.

Any chance of finding a compatable 12 volt motor?

I'm gonna take it to a motor place today and see if they can do that.

I didn't have any luck finding a compatible 12V motor at the usual local auto parts places or in the internet.

I think maybe I'll use two six volt batteries wired in series and pull six volts off the center of them. I did that with no issues in my 51 caddy hearse a couple of decades back.

ditch the 70 yro fan and put a modern 8" spal fan on it. gives you closer to the firewall space too

Actually the fan sits under the horseshoe shaped heater and sucks the air down, so I am not sure if any kindof modern fan would work. I have a small one on my race car I will check to see if it might work. Are any dc motors capable of running different speeds? I think maybe yes.

Dc motors are variable in speed.

Why not post a drawing of your motor with dimensions. Some member may have a 12 volt motor around similar enough to work for your application. Without a small motor catalogue it might be hard to find a 12 volt equivelant. Motor manufactures many years ago needed a way of identification so they technically identified and cataloged them. Frame number comes to mind.
