Just an update on this machine. I was able to bend the spool pin back into place without any trouble. I attempted to fix the dented motor tire with sugru. It seemed like a good idea, but the sugru does not have enough grip on the disc wheel, and instead spins uselessly against it.
I have ordered the Kennmore tire #5767. The diameter should be correct for the motor shaft on the Domestic. I also ordered a replacement lightbulb. Fingers crossed.
