Here's a diagram, anyone know how to correct and/or which way to loosen Part 3 and part 64, Reversed threads?

Thanks

I found it has Locktite that needs to be heated and has reverse threads.
It is currently stuck in the Impact bolt.

Follow up, I got it apart, Got the bit out, and my Factory Makita Bits slide in and out with no problem, This one on off brand 4" Carbide Core bit which I had gotten especially for Cutting in Octagon boxes into Concrete block or congrete. This happened on just block and was catching on the Ladder wire in between. The excessive force was from hanging on the metal, not so much impact. I'm thinking the Splines "twisted", not "compressed" on the bit?
