What would cause this type of wear on the helix & on the inside of the shaft? The two grooves that are worn into the side of the helix are not very deep but the side of the button post is getting a little thin. The only thing I can think of is that this button was wearing out faster than the others because the clutch was out of balance.
Does anyone have a secondary they don't need?
