Thanks for posting. Looks like you need a new spiral balance. See either our S600-18 or S900-18. The only difference between these two balances is the diameter of the outer tube, so compare both with your old balance to see what matches best. Also make sure that all other dimensions such as length check out, just to be safe. You'll need a red color tip option. Many thanks.
