    I have the 671M-1 motor in this unit. I have read that a 25 tooth gear wheel [worm wheel] is installed. Does anyone know if a motor mounting shim is required in the 1948 model? Did Lionel compensate for this change and no shim was required "or" was a motor shim included? [prior models had a 23 tooth gear that required a shim if the gear was changed to a 25 tooth]

    The one I am restoring doesn't have one or it was lost. I have searched nearly everywhere to locate one,.. just in case. Or,..does anyone know what thickness this shim measured? I may have to make one.

    Lionel's original part number is: 726-127
