View Full Version : Problem with SKS self loading

March 7, 2008, 07:45 PM
I bought a Yugo SKS a year ago and have had problems with it auto loading. I've cleaned out the gas tube and don't see any gas escaping when I shoot. However, it never ejects the cartridge let alone reload. I end up using it as a bolt action. I used both wolf 7.62 and remington but nothing seems to work. If you have any ideas how to fix this I would appreciate it!

I'm not a 'smith but had a Yugo.

Some have reported gas valve issues with the Yugo. Stating the obvious, did you check to be sure it's in the right position? One allows for bullet/ammo use, the other for the grenade launcher.

Otherwise I'd take it apart and clean it really good, or just replace it if that doesn't work. Also there is a small rod that pushes the bolt back when the gas operating rod hits it. Check to be sure that is working freely.

That being said, I sold my Yugo, bought a Saiga and haven't looked back.

I fully agree with the cleaning advice, the bolt and carrier group, the transfer piston and the gas system could all be contributing by causing friction and robbing power.

I've had two cases where a Yugo was failing to eject/load, both times I ended up buying new gas valves and installing, as well as getting a gasport tool and reaming out the port really good (a small drill bit will work, too, just do it by hand). The valves had been corroded badly and I think enough leak by was occuring that it caused the rifles to malfunction. In both cases there was not a apparent gas leak when fired.

There's also some info on the web of guys who've used teflon tape, O-rings and copper wire crush rings to seal their rifles up, haven't tried these myself and would recommend doing it the way you know is going to work, by replacing.

Ebay had one gas valve I ordered, I don't recall where i got the first, any web search should lead you to one, however.

Good luck... my Yugo is a great shooter now that she's right.

You likely won't see or otherwise notice any gas escaping, but the problem you describe is almost always a gas valve problem. Google "yugo gas system fix" (this will be a temporary fix) or just order a replacement gas valve from CNC Warrior and be done with it.
