Continental Bandsaw

Hello,
We have a Continental 100M horizontal bandsaw that we need to get the drive wheel off of.
There was a SHCS in the center of the collet looking hub. The diameter of the large thread is bigger than the bore on the wheel.
Does anyone out there have the secret to taking it off? A parts diagram would really be awesome!
Thank you very much, Gary

Saaweeeet!
The small 8mm bolt was holding the collet into the bore and the large nut was able to pull it out.
