Thanks for your help everyone. While I've been wrenching for over 30 yrs I never considered upgrading to an impact wrench. Lordy be, the TR crank bolt just spun off - right now - with a simple $29 1/2 drive from Harbor Freight. I've had compressors for years...why didn't I get an impact wrench sooner.
Thanks again - the beauty of the internet and these forums.
