Help removing a Snap On air hammer chuck

[Superdavey]

So I bought a used CP715 air hammer that came with a snap on PH200D quick change chuck on it and I'm having a heck of a hard time removing it from the threaded barrel. The issue is that the part that threads on to the barrel turns both in the left and right direction, but won't actually thread out or even tighten for that matter. I can't tell if the threads are stripped or if there's a special way to remove this chuck? Every snap on air hammer video I watched, no one seemed to bother taking off the chuck .. So I have no clue.

The threads on the barrel of these air hammers are fairly heavy duty so its hard to believe them being stripped. Generally these chucks have set screws that need to be tightened once the chuck is threaded on but I don't see any on this snap on chuck. So, I'm hoping theres something other than the threads that are preventing it from spinning out. There is a small pin hole on the back side of the chuck that I hope is for an alignment pin or something that helps thread it out?

In any case , the air hammer works so I can leave it on there for good but it would be nice to take it out and clean it up or thread it on to another hammer if need be.

Has anyone had this issue or know of a way to take this chuck out?

Like this? Any threads showing on the ****** in the gun? I assume the quick-change is a female, and threads onto a male ******. No way to grab the male ******? If any of it's exposed, I might try drilling a hole all the way through it, and use a rod or a phillips screwdriver to hold it stationary, to unscrew the $$$ Snap-On quick-connect. MSRP is $86!

when your quick-disconnect costs more-than your Chicago Pneumatic tool does!

No, but Mine looks very similar, although a little bit more beat up .

in the second picture you can see the pin hole I was talking about earlier , if anyone knows what that’s for?

I’m thinking of jamming an Allen key in there and hoping it locks the barrel up from spinning for no reason

That’s just it . Although I like the air hammer , I like the snap on quick chuck even better !! I would hate to have to drill into it . I thought about cutting the barrel at the chuck and boring out threaded end once the hammer is caput , just to save the chuck later

on all the ones I have is the threaded part is a plastic sleeve and after years of use they no longer tight to the body of the chuck that is why it just rotates and wont come off or tighten. Probably leave until it dies is the safest

hmm.. Interesting choice for snap on standards

Well... I’m happy to report that shoving an Allen key inside the hole in the back of the chuck managed to press the PLASTIC threads down enough for it to catch some grit and thread out normally ...in case anyone else comes across this problem in the future ..

this must be a common issue for them to include that feature .

A set screw just seems a lot more practical in this case ..
