This machine was never opened before so I'm going to say that the
wheel was made as cheaply as possible. It was stored for a while and
maybe sitting around in the garage may have exposed it to
temperature extremes. In any case, thanks for the great links. That
allowed me to search for the rubber ring

($4 + $3.25 shipping) instead of the whole assembly (~$19 + $11
shipping).

I don't think that will work. That's for a babylock series machine.
The CS-80 is not listed on the list of compatible sewing machines for
the rubber tire. There was also a note on one of the pages I listed
indicating that the rubber tire was NOT available seperately. Unless
you want to experiment, methinks you will need to purchase the entire
assembly.

Nothing useful in the manual:

If you want to go cheap, measure the size of the rubber tire and visit
your local plumbing or hardware supply store. Dig through the pile of
rubber faucet gaskets for something similar. The exact shape and size
is not very critical, as long as it makes contact and doesn't slip. If
you're really cheap, get a slightly larger o-ring, cut it to size, and
glue the ends with cyanoacrylate adhesive. There might be a slight
bump as it turns, but it won't affect anything.


The new tire arrived and it fit perfectly. The dimensions of the unmounted
tire a

16.5mm o.d.
9.8mm i.d.
3.7mm tire thickness
