Sorry if this comes in late. Is your aluminum bell old or new?
I tend to agree what joemugen has mentioned. However, I have found that if the 2 speed aluminum bell wears out in the inner side, the gap between the white shoe and the aluminum bell widens and any which way you adjust the spring tension on the shoe would not make the 2nd gear shift. I find that if you do not sand the white shoe with sand paper to clean it (very bad idea), the white shoe seldom wear out. The aluminum bell wears out faster.
That's the time you know that you have to get a new one.
From what I can remember, when the aluminum bell reaches to 0.5mm thick, then it's time to change.
