Strike 2. Ordered and got the Grizzly Arbor Chuck. Doesn't work.
Called Ryobi, they say it's a 5/8" -11 thread. So I guess that it's an 1/2" arbor doesn't mean anything.
Sent a detailed email to Grizzly Support...we'll see if there's an option.

Ben was of course talking about a Ford wrench (8 pound or larger hammer). This may sound like a pain in the patuty but maybe you could trade that 1/2" for a 5/8" at Grizzly http://www.grizzly.com/products/Motor-Arbors-5-8-Arbor-1-2-Keyless-Chuck/G5553 same price, just shipping costs, yea, I know it sucks but whatcha gonna do? I think most of us have had creative tooling problems like this, I know I have in the past. while looking for information for your arbor problem I came across a robotics site that had a step by step detail of how one person ground down a 5/8" motor shaft to meet the 1/2" arbor adapter size and they also flattened one side of the motor shaft for the set screws but, I thought that was more than you would want to do with a brand new grinder shaft.

Good luck on your next decision to solve the keyless chuck problem.
