    Default Century A66C motor cross reference

    I have an old norton universal grinder. Really nice machine though missing the swing down ID spindle.

    The problem I have is the hydraulic pump is a 550v .5hp 1725 rpm century electric motor. Need to replace it with (no transformer) a 208 motor. But cant figure out how to cross reference it. It is an A66C type motor. Face mount with a much smaller pattern then a c face
