If Allen wrench loosens the truck clockwise as written wouldn’t you be hitting it the other way ? Not sure if I’m not understanding correctly or reading something wrong. Thank you

Your comment ‘The chuck screw is reverse threaded, which means you will need to unscrew it counterclockwise. ‘ is nonsense.

A normal screw is counterclockwise to unscrew.

What you meant to say was

‘The chuck screw is reverse threaded, which means you will need to unscrew it clockwise. ‘

You might also like to add the the screw is often coated with loctite and very difficult to remove. A high quality tool and plenty of force may be required to remove this screw.

I think the clockwise thing wasn’t that hard to understand, but personally, my chuck screw was actually quite easy to remove so it wasn’t a problem for me

Here’s a short video on how to fix a chuck on drill. The screw that holds the chuck to the drill broke and needed to be extracted, and replaced.
