I got a Sig P320 in the shop today with with loctited extractor and extractor plunger! Yeah, they installed a RDS and put so much threadlocker into the hole (everywhere, actually) that it formed a ring around the plunger inside the hole, the spring and the extractor. I was able to remove the spring, by destroying it but the rest won't budge... I tried heat, brake cleaner, aceton, oil, scraping, punching the extractor - nothing. Any ideas on how to deal with it? _ _ _ _ _ _ _ _ _ _ _ Russia promises when it is forced to do so, and breaks its promises, as soon, as it has the strength to do so.

Soak it in Methylene Chloride. But it will eat non metal items and many finishes as well. Used to use it in the fiberglass industry to eat cured resins from tools and chopper guns. Loctite should be a cake walk for it. | |||

Back in the olde days in the USAF we used MEK or carbon tet. After they took all that away, we used acetone, took longer but it will break it down. Same "be careful" as M-PaPa said. "the meaning of life, is to give life meaning" ✡ Ani Yehudi אני יהודי Le'olam lo shuv לעולם לא שוב! | |||

There are different kinds of threadlocker that get deactivated in different ways. What does it look like? Red needs heat, and lots of it. If it looks white and chalky, it may be a silica-based threadlocker like Hot Lock or Rocksett and you can hit them with a torch until the cows come home and it won't do anything - you have to soak them in water. Boiling the part in hot water will usually do it pretty quickly with those. I've used PB Blaster with mixed success, I don't know that a solvent would do much with one of those. ______________________________________________ "If the truth shall kill them, let them die.” Endeavoring to master the subtle art of the grapefruit spoon. | |||

Thanks for the inputs. I don't want to use any harsh chemicals on nitrite finish but I'll try boiling it, as it shouldn't do anything bad to the finish. For now it's soaking in penetrating oil but I'm not holding my breath. _ _ _ _ _ _ _ _ _ _ _ Russia promises when it is forced to do so, and breaks its promises, as soon, as it has the strength to do so.

I've used a soldering iron to free a screw that was loctited in. | |||

Nothing yet, today was a Holliday in DK and I'm only working in the shop part time but I'll post when it's done. _ _ _ _ _ _ _ _ _ _ _ Russia promises when it is forced to do so, and breaks its promises, as soon, as it has the strength to do so.

What color locktite ? If it was red, the locktite website say you need to heat to 500°f. Call locktite if you know what flavor was used. Loctite Threadlocker Red 271 is a permanent solution for locking and sealing threaded fasteners and is only removable once cured by heating up parts to 500°F (260°C). https://www.loctiteproducts.co...AP_0201OHL029W5.html | |||

Well, it's done but not by me. The job was taken by another part time employee, he only comes on Wednesdays. After doing everything I've already tried, he finally drilled a small hole in the plunger, just behind the extractor. He used it as an anker point for a punch, so he could separate the plunger from the extractor. After the extractor could be removed, he punched the plunger out the rest of the way. It took him an hour and a half... and he left the rest for me, I heard he cursed a lot. I cleaned the rest of the residue (there was still a lot of it in there), reassembled the gun with new parts, remounted the RDS and test shot it. Final tally - new plunger, new plunger spring and a couple of hours of shop time, just because an idiot used so much toctite. _ _ _ _ _ _ _ _ _ _ _ Russia promises when it is forced to do so, and breaks its promises, as soon, as it has the strength to do so.

It's not that I didn't have "drilling it out" idea, just wanted to use the least invasive methods first but, yeah, I'm glad he did it. _ _ _ _ _ _ _ _ _ _ _ Russia promises when it is forced to do so, and breaks its promises, as soon, as it has the strength to do so.

I feel your pain! It’s tucked away in the basement storage of the Sig Forum, but I posted a rant about an idiot I worked with years ago. Dumb-ass used “the red lube” to lubricate his AR. Yep… Red Loctite. It took me a few days of soaking it in acetone and some other stuff and 2 or 3 dental picks. I can’t remember what brand of AR, but it was a higher end one, $1500 - $1800 or so, and this was around 15 years ago. Damn near ruined by an idiot with $12 worth of Loctite! Whoever used red - the permanent Loctite on your gun needs to be slapped in the face with a large purple sex-toy in public. ______________________________________________________________________ "When its time to shoot, shoot.

Working with other peoples guns is frustrating, to say the least. Today I got a Beretta 92, that we got in a trade from a customer. The entire pistol was covered with some kind of sticky grease and powder residue, it's unbelievable that gun still worked. A couple of months ago, a guy came in with a P226 X5 with the barrel installed up side down and he try to convince us that the barrel turned on it's own, AFTER he reassembled the pistol... Unfortunately it's not limited to the guns, I used to work as a technician in a computer store, I quit when I started to have nightmares about customers computers. _ _ _ _ _ _ _ _ _ _ _ Russia promises when it is forced to do so, and breaks its promises, as soon, as it has the strength to do so.

I know you got it unstuck, but the answer to your question is heat...using a heat gun using higher setting. ...and I agree with Greymann. When in doubt, call Loctite. Proverbs 28:1 | |||

Just to be sure what we were talking about, let's review: - I did try to use a heat gun, it didn't to anything and I wouldn't expect it to. Remember that it was not a screw, you can not turn it after heating, you can not push it because the two parts have to move in two directions simultaneously - extractor out of the cut and the plunger rearward inside a channel filled with thread locker. I also have to consider the finish of the slide. Second, I don't actually know what brand or type of thread locker it was, calling Loctite would probably result in their recommendation to buy a bunch of their over-priced products, which probably wouldn't work any better then acetone or brake cleaner. _ _ _ _ _ _ _ _ _ _ _ Russia promises when it is forced to do so, and breaks its promises, as soon, as it has the strength to do so.
