New OEM replacement gear motor for Keystoker Koker coal furnace and boiler units running a direct vent system with the Koker stoker assembly installed.

Merle-Korff

Model B4415/4415UI

Body measures 4.75"x2.75" and has spade terminals (if you have wire leads on your motor, you need a different motor!)

This gear motor does not fit 90kBTU stoves, please see our other listings!

UPDATE:: keystoker redesigned this gear motor in the spring of 2025. The new design no longer utilizes the additional small shaft and white fan on the motor. See last two photos for image of new design and the unit that we’ll be sending you. This is direct OEM part.
