if it is the diameter of the clamp issue , then only solution is clamp replacement. Seems like if you have 2 clamps and each is different size, then who ever sold you machine had multiple clamps and evidently gave you a wrong clamp. Like someone stated call Alpha.Seems like clamp is needing replaced for proper one.
