It would be a standard low speed 1725 oil burner motor.Any supply house would have one I have not replace one in a dogs age.Sure it's not the pump that's bound. I would recommend a complete up grade.

There was an error rendering this rich post.

    need new motor for old furnace - how to find?

    thanks to anyone reading this - on our NoDak farm, we have a 60-year-old oil-burning furnace and boiler from National-US Radiator corp - it works great, except the gun motor (that drives the oil burner) has frozen up and needs replacing.

    We know it's a Westinghous Thermoguard Oil Burner motor, 1/6 HP, 1725 RPM, 60 cycle, 115v, 3.0 amp. type FM -

    Unfortunately the part of the label holding the "frame" number is partially corroded, so we can't tell if it's frame number 50 or 56 or 58!

    It connects to a National-US Oil Burner, Model NB2 (J?), with a capacity of 2/gph.

    Since National-U.S. is no longer in business - how can I find out which replacement motor to buy?

    thanks in advance for any help with this!

    Replace the burner completely. Couple hundred bucks at most will give you piece of mind.
  • Keith is right

    it's time to upgrade to a high-efficiency "flame-retention" burner, and if the firebox is cracking replace that too. You'll save at least 10% on fuel consumption, as the new burner will generate the same heat while using a lower firing rate.
