Thanks, appreciate the guidance. Despite how it sounds I’m a racer from way back. I’ve never had this happen before, hence why all the questions so I can be sure it does not happen again. Not sure how or why it happened this time, but it did. I had even been using a fresh Allen key, and specifically segregated it for pinion duty and nothing more. I guess it must have been slightly off, enabling me to strip out the set screw while also getting an above average bite on the motor shaft. Then I could not find a tool or a way to remove it without getting messy.
Hopefully the new tools and new gears will help me to not have this happen again.
