How to remove a seized choke?? And fix the ejector?? Oops!

I already broke the piece that the ejector spring sets in (ejector?) I obv left the barrel attached when I was trying to remove the choke and it snapped. I put a ratchet in the choke tube and cranked the choke tube. It was unscrewing but it was all I had to move it. I probably messed it up. In case I didn't what do you use to get the choke tube unstuck?

Also I was told I need a special tool to fix the ejector? I think I saw it at brownells for like $40 (rivet cutting tool?) prob just let the gun smith do that

Seized chokes can sometimes be easily removed by letting that area soak in a penetrating oil like Kroil for a while. Sometimes you may also want to tighten it a smidgen to break it loose, then unscrew it. There's using a hair dryer or hot air gun, as well as freezing the barrel.

Once you get it out, use a good grease or anti-seize on it, and remember to take it out and clean the tube and the barrel threads, especially if you have been out in wet weather

I'll let someone else address the other issue

My brother welded 1/2" square socket wrench driver on a choke wrench.
He soaks the rusted choke with Kroil and then hits it with the air powered impact wrench.

That's a great idea, thanks.

inquiring minds want to know did you get the choke out?

 

[mcfadden222]

Kroil and an impact wrench worked wonders. Still have not fixed the ejector though ):

did the threads gall?

Even thought the impact wrech idea seems like overkill it worked nonetheless.

I do the same thing except with and impact driver that you hammer on. I have only ever needed to use it once.

The best thing to do to keep chokes from becoming seized is to not tighten them down too much. 19 out of 20 people will think you need to torque the snot out of them when you really only need to get them just snug.

Other than that Kroil is awesome.

Actually the best way to keep choke tubes from seizing is to lubricate the threads when installing them. Birchwood Casey makes a fine choke tube lube that only costs $7 per tube for enough to last a lifetime.

I give mine a quick spray with resizing lube just before threading them in. And I don't over tighten them of course. Honestly speaking, I can't imagine how the ejector spring got borken? It shouldn't take but a few minutes to replace it if you have a tool to drive the retaining pin out and are at all familar with these type tasks. Just don't go cutting anything out or using a rivet removing tool or you might chinger the surface and create a gun smith repair. I would guess a smith would only charge a few bucks to replace the broken spring. It's probably one of the few things that ever breaks on those work horse shotguns. I have several, my Son's have several, and some are as old as the hills and have never had a break down.
Good luck !
