Found one of these yesterday in very good condition. I wanted to do a disassembly for cleaning but information is pretty sketchy. Any one know the ins and outs?

All I found on youtube was for the 30 carbine. This Erma 22 is completely different. I did find this. Very detailed instructions with excellent photography that Erma/Iver Johnson never provided.

ERMA-Werke

The instruction manual that came with the gun lost a lot in the translation from German to English.
 
Loaded the mag up for a function check and, what a mess. Failure to feed, FTE and other things. This is a unique design and parts are scarce. The ultimate source of the problem was the trigger bar plunger spring which works with the sear and sear plate as well as the disconnector., They don't call it a disconnector but that's what it is. The spring was apparently broken on a previous disassembly/assembly. If you think about buying one of these interesting rifles, do a thorough inspection. I bought this one at a gun show and they frown on chambering rounds in a gun.

Bob's Gun Shop, Royal, AR has some parts. Waiting on parts and hoping for the best.
 
Had one of those. It was a fun gun but finicky about what you fed it. Liked to be run wet.

I could take mine apart but it was not something done casually. Numrich has a parts diagram that helps. Basically take the action out of the stock, one screw and the barrel band. Remove the recoil spring guide rod and springs. Laying it on its side, remove two pins and a screw, or maybe two screws and a pin. Left up the back of the receiver cover, carefully. The op rod will come with it. The bolt, recoil spring, and firing pin assembly sit on top of the trigger guard and can be lifted from the trigger guard. GO NO FARTHER. There are all sorts of little springs in the trigger group, the sear spring has a nasty habit of falling out.

It isn't too difficult but you need go slow and make sure parts don't disappear.

Sold mine years ago when I got a real carbine. I don't miss it. The magazine feed lips are rather sharp. An afternoon's shooting could get painful.
