You pulled the retaining ring off the end of the chuck shaft. Not to worry go to and type in your model number and it will take you to a page where you can download a schematic on the repair of this.

Air opertes but locks up under load

Sounds like you might have a problem with the hammer (clutch) mechanism, these types of impacts are direct drive there a re no gears, so the hammer (clutch) mechanism must have the ability to splip after impacting to allow the air motor to turn. Disassemble and look for broken hammer pins, hammer dogs.

I received a Craftsman 12V Impact Driver for Christmas. Any quick-connect bit that I insert into the driver seems to be loose. Is this normal? Am I doing something wrong?

do your bits have a recess cut into them to lock into the mechanism?? and yes there is some "play" in the bits as long as it doesn't get worse I would think that it is normal

Dirver won't impact working like drill...

Depends how old the tool is and how hardly/frequently it was used. It has mechanical impact mechanism, not a electro-pneumatic. And mechanical one can be worn off after certain period of use. If your drill is new, issue can be either "wrong tool" - then return it to the shop, or you have not turned hammering on - check user manual. Impact effect will occur only if you put a pressure on the drill bit. Juraj

Someone stuck a conventional driver bit into the impact driver and it is stuck tight.

VERY GENTLY. . . . use a flat tip screw driver to try to push the collar forward so that it will release the bit. You may need to gently hold the handle of the impacter in a table vice or something like that to steady the tool, then push forward on the collar with a screwdriver and use a pair of pliers to pull outward on the bit at the same time.

Or instead of a screwdriver try vicegrips that are adjusted loose enough to just lock but not squeeze when closed. Pliers that grip too tightly may bend the collar and keep it from being able to slide forward to release bits.

Cannot remove drill bit from self locking chock

If you are having trouble turning the chuck to remove the drill bit just wrap a cloth around it a couple of times and use a pair of adjustable channel lock pliers to give yourself a mechanical advantage. If you have loosened the chuck but can't remove the bit just clamp onto the bit with a pair of vise grips and tap them a few times with a hammer while a friend holds the drill for you.

How do you change the drill bit for a Ryobi?

My husband explained this, via phone ..... made it simple....... grab the silver ring area beneath the black top area where the drill bit is located. Hold the silver area firmly, while you twist the black top. You will see the release, then remove drill bit. Laymen's terms, but it worked!!
