  • Motor contactor

    I have a flaky contactor on a Model A machine. Checked the big "B" book. Part number 12-860621 is a replacement for it, but does not show the heater element. Where is the number for the element? What rated element is to be used? Yes,I still have those old GE motors without thermal overloads. I must have the kit with overload protection. Just want to get the correct element when ordering the kit.
    PS. the text says the unit comes fully assembled..look at the pic!! [img]/content/btubb/images/%%GRAEMLIN_URL%%/laugh.gif[/img]

    Bill:

    Changing out an old one requires overload relay x73c, and heater x74B. Match the heater to your motor's rated draw (amps), and then I'd add 5% ... there should be an amperage value real close to that number.

    The old federal pacifics had the overload stuff built into the contactor, new ones need the stuff added:

      If you will post the RLA amp draw here I have a chart and I will figure the exact one for you.

        Plate on motor says 8.6 amps. Does someone have the instructions for the kit? Somehow they have been misplaced. The pic I am talking about is on page 12-5 in the Genuine Parts catalog that is sent out by the distributers. I have the kit, just no instructions or heat element.

          Rake sweeping out of time, and pin launching onto lane.

          I work on some nice old Brunswick A-2 pin setters. Most issues I've come across haven't been to problematic to figure out. But being I can't seem to get it to recreate the issue...
