Ken226 has it right. However, what happened is the small platform (best seen on the left end of the encoder as a small rectangle) is the part that broke off. The ball and spring were attached to that area and also came off.
The good news is Precision Matthews has a repair part in stock and I should be back in business soon.
Thanks for all the help to everyone.
