I have a Saiga 7.62 that I need to press the barrel out of. I have a press kit from xebec and a 20 ton press. To make a long story short the pin will not budge and I've put enough pressure on it that if I apply anymore it will damage something. Does anyone have any suggestions? My last pin on my 74 kit came out with ease but this one is a real bitch. Thanks for any help. |
That Kroil really works huh? What did you use to heat the trunnion? I have a heat gun but no torch. Thanks for the quick response. |
| If you have to drill it out. Ive done several this way that were to tight to press out. After drilling a hole through center can either beat out or drill completely out. Just depends on how tight they are in there. Ive probably pressed out a 12 or so pins from kits and my press plate from Xebec is startingto sow a lot of wear thus making it harder to press the barrel pins out. |
I noticed that on my AMD65. I put some 3in1 oil on it and heated it lightly through the hole between the RSB and trunnion. The oil just sucked right in. When I put it in my big vise it was already cooled and made that pop sound 3 times while turning it down. Only thing I can figure is the heat breaks the 'weld' the parkerizing puts on those pins. |
It is called capillary action. The same principle is involved when soldering copper pipe. You heat the pipe at the joint and when the solder melts it is drawn into the gap between the pipe and the joint. Thanks for the barrel pin info. I have a few barrels to press out using xebec's kit. BTW, Kroil rocks! |
Kevin, did you have to press the barrel out of your Saiga AK-101 build? Also, what press kit are you using? Xebec's? The pin in my Saiga is so tight that it actually mushroomed the tip of the pressing pin Xebec includes with his kits. I went and bought some penetrating oil today and a propane torch. It's not Kroil, because I couldn't find it, but hopefully it works just the same. It's called Liquid Wrench. |

I did press it out and it went like a charm. Damn, if it's mushrooming the pin on Xebec's kit the it has got to be stubborn (I did use that on the Saiga, but it was my first out of 6 builds I used it on) Liquid wrench is good stuff, I forgot about that, I have used it many times when I was wrenching on cars. If that doesn't work, you may take a few good whacks at it with a BFH and a punch, just don't use some dinky ass hammer. Just to "jar" it then try pressing again. Did you try pressing from the other side? It may be worth a shot. Good luck. Sounds like you may need it on this one. |
| I will try the Liquid Wrench and if that doesn't work I will just drill it out. I don't see the risk in applying more pressure than I think is necessary only to damage the rest of the rifle. I can get a new barrel pin for a lot less money than I can get a new Saiga rifle. |
