Spiral Balance needed

I'm afraid you can't replace that white tube. You'll need an all new balance. I would also confirm the outer diameter of that tube. It should be more like 9/16". I don't believe any balance in this style was made with a 1/2" diameter.

If so, then I recommend our Series 600. I feel confident this will work as a replacement for your original balance.

I understand you concern. Personally speaking, whenever I used our metal tube Series 600 balance to replace the old plastic tubes, I never ran into any issues. I think you'll be okay.

Specifically, you should consider our S600-25 with a blue tip. Our 75-006 charging tool will also be very helpful when you go to attach the new spiral to your pivot shoe.
