Keyless Chuck Help

[redpoint5]

I've got a Ryobi drill (P252) with a wonky chuck. Over time it seems to be creeping forward. It's not lose, but the green band behind the chuck shouldn't be visible.

Online videos all show the removal of a center screw, but this chuck doesn't appear to have one. Any ideas on how to remove or tighten back?

Looks like a hex drive/Allen wrench might screw it back in.

They are on a press fit tapered shaft SOOO: whack the end with a hammer, find a screw that fits and tighten. Should be like a 10/32.

So I lost the center screw? It's difficult to see in there, so I couldn't tell what I was looking at.

Thought the hex might be meant to hold bits, but now that I see it on a big screen, it looks like it has a key on one side.

Not sure it's much help, but mine looks nothing like that inside:



The screw is a left-hand thread and a much larger diameter than that tiny hole at the bottom of yours:



Model # of mine:



My older one is the same:



Think mine is taper-fit, so it needs the screw. Yours looks like a pressed-on hex with a key, which doesn't necessarily require any kind of screw. If you can find one that fits and a washer, you can use it to press it back in...if not, well, not sure if hitting it with a hammer hard enough to get it back on wouldn't break things inside.

That sounds like a job for Internet. duckduckgo.com/?q=keyless+chuck+diagram

Your's is what 100% of videos online show. Zero show mine.

The hex and key is for putting quick connect bits in without messing with the chuck.

The center "thing" deep in the chuck in my photo has a circle in the middle, so there's no way to get a tool in there to twist it.

Maybe my tool is just press fit. I wonder how it came loose considering I've done nothing strenuous with it, and haven't even used it all that much.

Looking at how far back your chuck's jaws are, and how they essentially screw in and out...maybe when you back it all the way out, they're pressing against something and pressing off the chuck little by little...?

What model # is it? We might have one at work that I can look in the chuck to see what it should look like.

BTW, "all the internet" thingies tell you to clamp the chuck on ones like mine to a giant allen wrench, and use the wrench to spin the chuck on or off once the screw is out. Doubtful, but perhaps that will do something on yours.

P252.

I see that as the 2nd step in all instruction too, but I'm hesitant to try that prior to confirming a 1st step isn't needed.

Will check tonight.

Edit:

This diagram doesn't show a screw:

Also doesn't show threads on the output shaft, so not much point trying to turn it, unless you're attempting to press it back on at the same time.

Odd. Maybe they just heat/cool the parts and put them together so they lock together.

Great. Google is stalking me. Now all my youtube video suggestions are for ryobi cordless tools.
