Can not remove coupler plug from impact

[Wrench master]

I bought a snap on mg725 off eBay it has a lincoln style plug on it and I can not for the life of me take it off I dunno why anyone would use so much torque on a air fitting I'm starting to think that the guy used lock tight on it how can I get this off should I use pb blaster or will that cuz harm to the tool or threads

Try a little heat, like a propane torch. I use liquid Teflon thread sealant, and find it seizes up like this.
HTH, Jim

Well, you're supposed to oil the inlet, so I doubt PB is gonna hurt. NPT is tapered though, so I doubt it's gonna be much help there, either.

Got another impact? I'd try chucking it in a vise, putting a wrench on the tool inlet, and try gunning the fitting out. If it's in tighter than that, I dunno what to tell you, that's insane.

This is what I was going to suggest. I have had to do this on one of my air tools. Use an impact gun to fix an impact gun.

Yea I thought about using another impact to rip it out of there but wanted to know if there was a more gentle way I could remove it lol

Find a way of securing the gun and use a manual impact driver if you're worried about using an impact gun. Just be sure to apply plenty of oil and allow it time to seep in.

This is said in fun, but you may have chosen the wrong screen name.

Or make an adapter to go between your hose and the tool.

 

[Wrench master]

Lmao that's actually pretty funny. I just cant believe how tight this fitting is I guess I will just use another impact I was trying to be carefull with it because its a "new"
to me tool

 

[blacK20]

How is it possibly that tight? Is the fitting moving at all? Or is it actually stuck solid?

 

[Wrench master]

It's stuck solid

 

[Outlawmws]

Try tightening it a fraction more and see if it will reverse after that. (weird as that sounds...)

 

[Givl Reggin]

Try tightening it a fraction more and...)

...twist it right off! Been there, done that! Heat plus a penetrate I think is the way to go. Remember you're dealing with soft (i.e. it's not a hardened grade 8 bolt!) metals here, so finesse is going to be the key... either that or leave it alone and just make an adapter to go between them.

 

[blacK20]

If all else fails and you break it off, I'm pretty sure you can buy a new inlet bushing and start fresh again.

 

[MrMark]

It's probably cross threaded.

Many of the good air tools have replaceable bushings as noted.

wtf is a coupler plug ?

 

[Drew_flux]

IIRC the air fiting screws into another removable fiting, with the mesh sound reducer under it. I think its a 19mm to remove. once you get it out,throw some heat in there and it should break loose.

 

[MrMark]

It's an NPT thread. I doubt it is rusted or corroded. It's just tight or stripped. It will come out just put a big wrench on it.

 

[Chadwilliam1]

replace the bushing.

So did lifetime SnapOn warranty replace your impact??

Shouldn't OP get replacement if impact can't operate properly??

Lifetime warranty on air tools ? You're making a joke right ?

Just the potentially broken piece that OP is talking about . . . not the impact itself.

 

[firebox40dash5]

He bought it on fleabay, and the piece that's having a problem isn't really even part of the gun. Sooooo.... yeah.

If that inlet bushing is replaceable, I'd definitely throw a wrench on it and try to gun the fitting out of it. If you break the fitting in a replaceable part, oh well.

 

[IngyHere]

Throw an old piece of carpet on the garage floor. Use a strap wrench to hold the handle and pin it down with your foot. Gun it off using a 6-point socket, or try an 18" pipe wrench (second option is worse, could break).

vice + breaker bar?

 

[OccupantRJ]

That would be the male part of a quick disconnect. The piece that screws into the air tool. Now you know.

 

[blacK20]

I think you're being too gentle... Put a wrench on the bushing and pin it against the ground with your foot. Put a long ratchet/breaker bar on the fitting and lean into it.

well, my friend it used to say on the inside of the cover of of every SnapOn catalog.....
"any tool bearing the SnapOn name has a Lifetime Guarantee"

thats why so many are now Blue Points

i bought my tools from the old SnapOn Warehouse in Torrance CA......i bought from SnapOn Corp directly, not from the **** heads on the trucks

 

[wise]

This is getting off topic, but Snap-On's newish 2 year air tool warranty is pretty much the best in the industry. Brass fact is Air Motors, Hammers and Anvils, and any moving part actually will wear out with use, so how could they warranty it? Buy one tool on special and expect a lifetime supply of tools that will wear out in a few years?

The only air tools I have seen that are life time warranty are cheapo mastercraft ones... but they're much worse brand new than a worn out Snap-On or IR...



For that plug... yeah, just give it the beans. Penetrating oil probably won't do much good. Heat will, but there are seals that might not like it. Short whapps with an impact should break it free, work your way up in power if you're worried about damaging anything, but like said, replacement parts are available worst case.

You couldn't be more wrong. I have a SnapOn Torquemeter wrench that is around 50 years old. The warranty ran out around 49 years ago.

The same reasoning that Craftsman uses to only apply to HAND TOOLS is the same policy that SnapOn enforces.

 

[Wrench master]

Thank you for all the responses I got it off with my cordless impact it was cross threaded but thankfully there was no damage to the threads on the gun
