Not sure what I need to order. The springs are stamped with the numeral 5. The housing that holds the cam broke. The left side which is broken has two coils and the right side has only one coil. Do I need to replace both sides in pairs?
Thank you,
Joe

Thanks for posting. When it comes to coil balances, you only need to replace what's broken. In your case, the only part that appears broken is the shoe, which matches our 15-180. If you needed the other parts, though, then see our 15-182 bushing, 15-186 clip, and then our S190-840 (for the #8) and the S190-540 (for the #5). Just keep in mind that balances should have symmetrical stamps on either side of the sash. |

Hey, Joe. I wouldn't guess. I recommend getting the exact weight of the sash, then dividing that between the number of springs used to support it. Since you're using 4 springs, you want to divide the sash weight by 4 and choose the proper stamp. For example, if your sash ends up being 20 pounds, then you want four S190-540 springs, which carry 5 pounds each. If it's 36 pounds, you want four S190-940 springs, which carry 9 pounds each. |

The springs will remain coiled even if you take off the screw. Unless they've completely sprung apart, and I don't believe they have, then they'll retain their current shape. We don't have these Z shaped pivot bars, but our 26-040 should work as a substitute. I know that ours doesn't have the same dramatic offset, but believe it or not that doesn't appear to affect the window function. It should all work normally. |
