So this definitely looks like a S745 type window ballast. I have include pictures, theses windows have a wood inside veneer, that is removed, then have to slide out the channel lock and then remove the window frame.

Our windows have a 23 1/4 spring frame in it, and the frame has a 3654 stamp marked on it.

Thanks for posting. Your balance shoe appears to look similar to the 16-027 that comes attached to our S745 balances. So it is likely this is the correct balance replacement.

Since your balance length is 23-1/4", I recommend the S745-23. To select the correct stamp you'll need to obtain the exact weight of your sash. Then you'll be able to select the correct option for the weight range your balances should be able to hold. The chart is located below the product description for the balance.

Does the stamp on the ballast 3654 not provide enough information to determine the spring type? I have had to reassemble the window and have no scale in the house to measure the sash weight.
Thanks

The stamp only indicates the weight range your balances should be able to support. However, in your case, I am unable to cross-reference the stamp you have with the stamps on our S745 balances.

You'll need to obtain the exact weight of the window to confirm the stamp you'd need to select at checkout.
