So long as all the spiral balances have outer tubes that are 5/8" in diameter, and you are obtaining the length by measuring those outer tubes, up to and not including the colored tip, then you need Series 600 Spiral Balances in every instance. I've listed the respective lengths on this page. For the pivot shoes, the first one in your photos might be the 15-046, but there's really no way of knowing from just this picture, as a ton of them look like that. You need to remove it and measure the width and thickness of the shoe to confirm if it matches up; let us know if it differs at all. The second pivot shoe is either the 15-178 or 15-188, depending on the dimensions; again, removing it to compare is the only way to confirm which. |
