Default (Update)Almost done demilling/disassembling my 1967 Romanian kit.

Almost done demilling/disassembling my 1967 Romanian kit. 'Almost', is the key word here.

No problem with the trigger guard, or any of the other rivets.

Got to the barrel pin, gave it a few good whacks with a sledge hammer and punch, it never budged. Only took a few swings for me to realize it was not coming out using only a punch and hammer.

Next I put a deep 1/2" socket on the front trunion with the socket opening over the barrel pin, shimmed one side so the socket would sit flush on the trunion and placed it against one side of my vice. On the other side I placed a 1/2" craftsman nut driver bit with the 1/2" side to the vice and the 'bit' end over the barrel pin. The bit end of the nut driver was just barely smaller than the pin, an excellent match. Held this combo steady and closed the vice with my knee. Once it was snug, I started hammering on the vice handle til it wouldn't turn anymore. Next I wailed on the vice itself with the sledge hammer. Pin started moving. Kept tightening the vice as the pin drifted, and continued smacking it with the sledge until the pin came out, took about 5 minutes.

No luck getting the barrel out of the front trunion yet. Tried putting it in the vice, stacked pennies over the chamber placed a piece of round bar over the pennies, then then beat on that combo with the sledge, to no effect (other than destroying a stack of pennies). Tried using my floor jack and a brass rod to push the barrel out, had to brace my work bench against the overhead beams in my garage using a section of 4x4. Stopped when I got concerned that I might jack my roof up.

Got some more ideas brewing in my head about how to get that barrel out (one of which involves modifying and old RCBS reloading press)

Anyway, my goal is to not buy any tools. I will not be 'refinishing' this gun when complete either...other than blueing the reciever. The wood is old and very worn, rifling looks very good, finish on the metal parts is well worn and that's how it's going to stay. I like the 'tribal areas' look"


There is no 'G' on the rear sight block. I guess since it has no 'G' then it's a Romanian PM model 63 AKM?

Is there a big difference between the quality of compliance parts? Since I want keep the furniture, which compliance parts should I get?

heat the barrel and trunnion just a little bit w/ a propane torch and let the penetrating oil seep in the small cracks.

I've been soaking it in Kroil and have considered applying heat. Not sure how much heat to apply. Guess a propane torch should be safe.

as long as you use propane and not Mapp gas then it should be ok to apply heat. That is what I did before removing my barrel and barrel pin. Just heat it enough so that the oil is absorbed between the barrel and trunnion.

btw..compliance parts needed are the FCG (3x), and the piston and maybe a muzzle brake + your US made recvr.

My 1980 Romy barrel pin took 56 tons (measured on the gauge) of my buddy's 100 ton press to dislodge.

Good luck.

Wow. Stuff like this scares me about the demilling party coming up. After dissassembling the bolt on mine I dread to think what that barrel pin is gonna be like. I am already soaking in penetrating oil.

Stick the barreled assembly in the freezer for a while. Then when your ready to push the barrel out, heat up the trunnion with a torch. The difference between the cold barrel and the warming/expanding trunnion will give you some room.

I do the same when inserting the barrel back into the trunnion. Freeze the barrel, heat the trunnion.

Keep pounding. If you have an air hammer you can use that instead of hitting the barrel with a hammer. If you can borrow one it will make it easier. But then again, so would a press and the proper tools.

Yah...I got a "tribal look" AK that I build with only hand tools (minus the receiver).
Popped out the barrel exactly the way you're doing it.
I soaked the barrel and torched it when I was ready to knock it out.
Quite a few blows with my 3 pound hand sledge to get it to come out.

Putting the barrel back on suxed also.
Freeze the barrel, heat the trunnion just like JeffM said.

Barrel pin was not that bad (in my case anyway), just use lube.

AK builds are a lot of hard work but incredible fun nonetheless.

My PAR-1's barrel pin and barrel were in there tight, but as others said, oil, heat, freezing, and a sledge will do the trick.

As for replacing the barrel pin, I just reamed the barrel pin hole and made a new pin on a lathe. Made for a perefct fit.

air hammer. hasn't let me down yet. Although I did have two pins that i had to drill 90% through get them out. Everyone always says to not drill, but personally, i would rather drill the pin and spend $5.00 on a new one rather risk screwing up the RSB or trunnion.

I tried this once and it expanded the pin in the RSB. Drilling is a pain.. If you have a nice press and solid jig you will be okay. Restoreit1 has some nice stuff. I think he is still around if you wanna buy some jigs.

Sorry, like it said in the post above I've been in Pasadena. Have to go to Houston this week and Maryland the week after, so it may be a while before I can get back to the project.

May have a few days in between my trips to Houston trip and Maryland, if so will try and bang it out.

Been busy with work and family so I haven't had anytime for messing with the barrel and front trunion until today.

A fellow Calgunner was kind enought to shoot me a PM, told me about how easy it is to get the barrel pushed out using a power steering pulley puller. So I ordered one for $5.99 + $8.00 shipping on Ebay. It got here today and 5 minutes later the barrel was out (thank you).

The penetrating oil I put on there a couple of weeks ago, penetrated well, the barrel and interior of the trunion were well coated. Was surprised how much oil had migrated into that tight space.

I originally had decided to try and use items I already in my had posession for this project, but......it started dragging out due to my work schedule and family issues and I want to get this done sooner rather than later.

So now I've dumped $13.00 extra into this project.

Still need a NDS receiver. Anyone have one they'd like to sell?

I do have a lead on a good kitchen table FFL from a fellow Calgunner, if no one around here has a receiver for sale.
