I'm replacing the (variable speed) pulley set on my 46-715 type 2 lathe. When the replacement part (#5140052-65) came in, it has an Inner Diameter of 22 mm, which unfortunately doesn't fit on the (approx) 24.25 mm diameter spindle on my machine. All repair sites indicate the repair part (5140052-65) replaces the pulley part # 909946, but it doesn't. What is the correct repair part?
