The Stovebolt Site Forums The Shop Area The Electrical Bay Getting heater motor out?

The heater motor in my '48 is performing off and on right before a cooling down period is predicted. 4 deg on Saturday night.

What am I up against in removing all the stuff to get the motor out? Does it all have to come out, core included, to get at the motor? Do I have to remove it piecemeal?

Thanks! I don't want to start this w/o knowing what's involved, especially if it's cold outside. (Mrs. Wally gets the garage!)

What model heater do you have?

Here's a picture. Heater.

You have to remove it from the truck to get the motor out.

Removing the front cover only shows you the cage

Wow! Thanks a million.

That's a fresh air heater. Just remove the entire heater and if you are not rushed I would break it down and rebuild it. That way it will give you many more years of service. If you need to replace the motor many vendors carry both 6 and 12 volt motors.

I just bought a brand new (12 volt) motor for my heater at NAPA. Less than 40 dollars. Fits perfectly. Mine is a recirculator type, but I am sure the one you need should be at about the same price range.

Is your heater motor 6v or 12v?

If your motor is 6v, some 'Bolters have replaced their 6v motors with 12v motors. You may be able to buy their 6v motor from them. Post an ad. Also, there are some guys who work on old motors that may be able to fix your 6v motor. I'm sure that other forum members can give recommendations.

If you motor is 12v, you may find a 12v motor from a '60s GM car ... probably not an easy find, but possible. I have a '60 Impala 12v heater motor in my '54 Fresh Air heater. Your squirrel cage will mount onto the 12v motor with no modification. You will need to file about 1/16" from the mounting holes in the heater case. (12v aftermarket heater motors also require this.)

Here is my original 6v motor on the left, the rusty '60 Impala 12v motor before sandblasting in the middle, and an aftermarket 12v motor on the right.

EDIT - I just noticed that your signature line states that your truck is 12v. The second part of my post applies. If you still have the original 6v heater motor, please don't toss it, another member may need it. Or, you can hide an (ugly) after market 12v motor inside the 6v case, like DADS50 did.

The motor is held in place by the shell of the heater unit which would have to be partly dismantled.

Inside this casing is also the heaters matrix and all the valves and gates for the ducting. To remove the heater as a dash has to come out, Not a job I would fancy. Some crafty/good back street auto mechanic may have a wrinkle or two but don't hold your breath.

The dash does not have to come out to remove a fresh air harrison heater on an Advanced Design truck .

Simply remove the bolts on the kick panel and the firewall

The duct hoses and two core hoses

One of the easier jobs on the AD

...would agree, put the 3 clutch head bolts on the backside of my heater were a bear to get out!
