I have a Craftsman contractor style tablesaw. Recently I lost the key
that is supposed to be placed in the keyway of the motor shaft. This
key is a small metal bar, and is ued to lock the motor shaft and the
pulley together. Unfortunately, the parts list of the tablesaw
doesn't have a part number for this part. I have called the Sears
PartDirect; but they don't have any info about it either.

I would like to know where and how to get that key. Is it a very
common part?

Thanks in advance for any info.
