If you only have one pulley on your motor and two on the spindle, then when you change speeds you will need to adjust spindle sleeve height to align it. Look for a bolt on the side of the casting that the spindle is in. if it's there you would loosen it, align the belt and then retighten it.
Right now I can't measure the sheaves on the spindle pulley on my machine. I had shoulder surgery last week, so my right arm is a little "limited" at this time, so I can't get in side the enclosure.
