Coil Balances
Thanks for posting! This balance assembly is made using the 15-177 Coil Balance Shoe. I'm confident this is what you'll need but be sure to carefully review and compare the dimensions below.
This shoe is compatible with the 1/2" thick Series 152 Coil Balance. They are secured to the shoes using the 33-072 screw. To determine which coils you need, you'll need to check for any stamps/markings on the metal. If there aren't any, please see the tutorial below for detailed instructions.
If you cannot reuse the existing coil supports, you'll need the 15-143 Coil Bushing, 15-144 Coil Bushing Cap, and the 15-145 Coil Support Barrel. You'll need them for each coil; all three pieces are used together to create the new support.
