Window replacement part

A quick learner from Cedar Rapids Iowa says:

We have some older K&K windows and the cylinder that opens combines with the wheels to crank open the windows no longer works in most of them. I was wondering if you can just buy that replacement cylinder rather than buying the complete arm insert.

You will need to replace the operator this part came out of. Start by looking at the 39-032 and 39-031, I looked up other discussions on the K&K window operators and this is a popular one for that window brand. If this does not match your current operator reply with detailed photos, we would be happy to research a replacement for you.
