The life cycle for spiral balances is usually about 10-15 years. The videos below show some basic things to know about identifying replacement spiral balances, as well as how to remove and replace them. |

Yes, it would be two spiral balances per window. We can't determine what balances you need from this information alone. See the first video above. You'll need the length and diameter of the outer tube, as well as the color of the bearing that the spiral rod emerges from. For a new charging tool, see the 75-006. |
