Yes, I just removed one the other day for the first time. I fired up the torch and put heat to it. Then I used a large pipe wrench strategically on the cog teeth to turn the cog. Threads are right handed. I hope this helps.

I've tried a plastic head hammer & Kroil, but heat could soon be on the list.

What if you convert a chain whip to skip tooth?

 

[zephyrblau]

the issue so far is not being able to prevent the driver from turning while applying shock therapy to the cog.

Might try reassembling wheel with cog in vise then rotating entire wheel

you are not going to hurt the driver in the vise. The driver is heat treated to a very high Rockwell. Grip it tight in the vise and put some heat to the cog. It will come loose.

Whip it good!

I like that! I've been using a chain vise grip for years. That looks like it would work a lot better.
