Insulation in spiral balance

Question

Attached are photos of my existing spiral balance.

There is, was appears to be, insulation stuffed up around the spiral
balance.

I'm assuming that I need to replace this insulation when I replace
the spiral balance?

Any information on this would be helpful.

Hey there! Thanks for your question. The foam part you are looking for is our 26-139 single hole aligner. They are usually used with the Series 600 tilt balance.
