Coupling Link Pin Removal

Thor · 02-12-2011, 06:24 PM

I sometime run in to this. The bad bad boys are the sear bar plunger disconnector pin (small as a push pin in diameter), the front sight blad, the coupling link pin, and the small pin that goes through the top of the rear toggle link that retains the middle toggle axle pin. Soak in Kroil 3-4 days, then put in a freezer in a zip lock to keep oil from getting in the freezer, leave it over night, then add some heat from a blow driver. Hopfully the metal around the offending part will be slightly larger (due to the temperature diffential) than than the pin and the pin can now be removed. Notice this takes a long time and a lot of patience. I just removed a Navy front sight blade that had been through Hurricane Katrinas salt water and the blade was damaged so I knew it would be tough, 3 days in Kroil and it popped out, YUREEKA!

PS sometimes I use a lead brickette (from handgun bullet casting operations) to hold the parts during the hammer/punch operation

...Maybe a "blow dryer"??? Like your wife's hair dryer??? No wives left here [hooray!] and they took their hair dryers with them...

Is there some reason (besides fussy wife) not to have oil in freezer??? Does it react with the Freon or something???

Do you punch the pin right into the lead brickette??? That's something I had not thought of...I sometimes do that with wood, but not on a Luger pin...I'll have to remember that...

Yes a hair dryer.

Yes, I do punch it into the lead, but then after it starts I put it on a punch thing that has several different size holes for the pin to move in.

In my house, the oven and freezer are shop tools...
