  • Electrical: 12 volt replacement Climatizer motor

    Most of the original components in my 2R pickup are still 6 volts even though it was converted to 12 volts. The truck had one of those big ceramic voltage drops under the hood to run the 6 volt items. I would like to convert everything to 12 volts and need a 12 volt motor for the type A climatizer. Has anyone found a good replacement?

      I wondered about drilling out the fan. The motors I found all seemed to have 5/16" shafts instead of the original 1/4". Thanks.

        Drill them out with a drill press, not a hand drill. After hand drilling mine, I had to ask a machinist friend to fix my terribly crooked hole.

          That was a concern. I do have a drill press available. Thanks.

            On my 53' R, I went through the NAPA on-line parts listings and found at least 2 that would fit: a Chinese cheapie, and a more costlier one. I went cheap and had whirling noises in the second season. It still works. Watch the rotation of the various motors too. Some go one way or the other, then some go both CW/CCW.....

              The 55 (6v) and 56 (12v) truck heaters were essentially identical, with the only differences being the fan motor and fan itself and the switch (which would work on 12v). The 12v motor and fan is part number 1685816 -- one of our vendors may have one.

                Good to know. I wondered about the later 12 volt versions. I like to change as little as possible for simplicity.

                    Mine from NAPA only has 1-2 wires (?). Maybe that is a generic pic....

                      Hi Jack
                      The picture on the link is the motor i have. The first one i got from Napa had the 5/16" shaft , I didn't realize it until i got it home ( seems to always be the story ,so i had to have one ordered with a 1/4" shaft as they did not have it in stock , ( took the counter guy and myself a little while of looking through the parts catalogues to find one, but i got one that could be hooked up CW or CCW and is a 2 speed motor.
                      The only thing i had to do was cut the through bolts on the shaft side a little shorter , the other end of the bolts fit in the end plate of the climatizer and they fit perfectly.

                            For the 1956 Transtar with the Type "C" Blower mounted on the Fender, this 1685816 Motor is a direct fit. For any of the "other" many types of Climatizers, not so much.
