I was a bit worried about the SKU matching up, but the 6615 code lined right up with my machine’s manual. The spring’s tension feels consistent and solid during operation.

This spring fits perfectly on my 7600, and the SKU code made confirming the right part a quick check. The tension feels exactly right for the assembly.

The spring matched the 6-45 reference exactly, so no fiddling around with fitment on my 7650. Swapped it in and the tension feels just right, like the original. Exactly what I needed for the repair.
