I got this video years ago along with one for the M1 Garand. http://store.ontargetvideos.com/SKS-Rifle_p_29.html I got mine from Cheaper Than Dirt but they don't carry this line of DVDs anymore. I see at least one E-Bay seller that has this for $14.99 and free shipping. Here's a pictorial, with one note: they suggest using a live cartridge to depress or move certain parts for disassembly and I'd suggest maybe using something else. http://www.gunpics.net/russian/sks/sksdis.htmlcjsimoh wrote:I'm acquiring my first SKS
With my Mosins, I've been able to "totally" disassemble them to remove the grease.
Are there instructions or tutorials anywhere showing how to disassemble/reassemble an SKS for grease removal?
I'm sure more than a field stripping is going to be required to get all of the "cosmo" out of it.
I've searched the 'net and haven't been able to find much on the SKSs...
That's the way to do it if you've got the right stuff. My ultrasonic is a jewelry one, too small for most trigger assemblies, and my compresser is buried in the garage.cjsimoh wrote:Thanks for the good advice. Sometimes with my other firearms, I'll put trigger assemblies in the ultrasonic cleaner. Then I blast them with air and put them by a space heater to bake off the rest of the water then oil them up.
It's still grease but it's just hardened. The US was the only place that used true cosmoline and it's a real bear to get off from what I've been told. I have one of these Yugo SKS's I got from Wideners a few years ago and like some of the Mosin Nagants that had dried grease I used Hoppe's #9. It won't harm anything on the rifle. It's petro based. I believe it actually has kerosene as one of the ingredients. It works but sometimes you need to let it soak. I paint it on larger jobs with a parts brush. It's also water soluble to a point. When I clean an especially dirty trigger group from something like a Ruget 10/22 or a Remington 1100 I just paint it on, let it sit and use an old tooth brush to give it a good scrub. I buy the stuff by the quart.cjsimoh wrote:Ok, so it looks like these SKSs have real cosmoline on them. Not there grease that the Mosins come covered with. Am I going to have to change how I go about removing it? The Mosin axel grease wiped off and then the remaining came clean with degreaser and the ultrasonic cleaner. I have a feeling I'm going to need to be more aggressive with the stuff that comes on the SKSs.... Maybe something petroleum based? I don't have anything to boil the parts in ....
I'm sure just about any other less expensive petroleum based solvent would do the trick.

"Tectyl 502C, Class I is a solvent cutback, corrosion preventive compound. The semi-firm film is amber and translucent. Tectyl 502C, Class I is approved under Military Specifications MIL-PRF-16173E, Grade 2, for Class I, and MIL-P-116J, Type P-2.

Here's a link to a product page: http://www.petroleumservicecompany.com/tectyl-502-c-class-1.html?gclid=CMK6yrjJtscCFQ6RaQodZKoGrg
There's a remover for it, but it's about $37 per quart shipped!

I'd advise you not to pull the trigger group apart; Once it's out flush it with Gun Scrubber (or brake cleaner, if you're cheap like me), and relube moving parts, and a very light coat of oil on everything else.
Remember the Yugo SKS' don't have a chrome-lined bore. If you shoot milsurp ammo, (Or anything made by any former ComBloc country) you must clean it ASAP.
