I cannot figure out how to remove the old extractor from the bolt. There seems to be no pin or other retaining element, as there is, say, for the firing pin. I have a replacemetn extractor. How do I get the old one out? Thanks,
There are 3 parts involved..The spring..the plunger and the extractor..It us the shape of the extractor and the preesure applied by the spring and plunger that keep it in place...You will need a sharp..flat and pointed instrument to lever the Ext out..What you do is to insert the tool between the back of the ext and the front of the plunger......pushing the plunger and spring to the rear and then prying the rear of the extractor up and forward.......Bear in mind that this is a "sprong" piece of work and can launch parts..into parts unknown..I suggest that you do the work...both in and out inside of a clear plastic bag to help retain any flying parts..BTW..IN is insert spring..insert plunger..press both the the rear with a tool and then drop in the extractor..You should check the fit of the ext prior to trying to assemble it.......applying a liberal dose of grease to the spring and plunger will help keep it inplace while inserting the new parts
I would also like to know why you felt the need to replace these parts..there are several other common 22 problems that result in failed extraction
Like
Dry fire damage
The FP will hit the face of the barrel at the chamber edge ..often denting the spot and peening metal into the chamber..THIS MUST NOT BE REMOVED..there is a tool and technique to repair it
The Model 12 is from the midst of the corrosive 22 ammo era
Chamber damage can result..pitting..rust which can grab the side of the cartridge case an apply a lot of friction
Also...It was also common to shoot the cheapest ammo..that would be a corrosive 22 SHORT and the damage would be at the spot where the mouth of that case rested in the chamber...feeding and firing of a 22 Long or 22 long rifle can result in light hits(not fully chambered round)..bad feeding and hard extraction
There is a few thing that can help there also..Check to see if you have them...post them here and i will advise
Also..if the extractor is NEW then there may be some shrap edges to be dealt with and the hook length may need to be fitted...

Perhaps I was presumptuous in thinking it had to be the extractor,instead of the other possibilities you mention that I never considered. We never, ever dry fire rimfire rifles. And by never, ever, I mean very infrequently.
But I have had this rifle for 30 years, and it only started to exhibit these extraction failures very recently. I only use modern .22 lr. ammunition, but of course cannot comment on its longer, earlier history of use.
When I have to manually extract a casing, it comes out fairly smoothly, with little of the friction that you mentioned. But I get your point. Might fine steel wool polish that area with damaging anything? I would try to see if there is any difference in the extraction effort before and after.
The new extractor is of a slightly different shape than the old, though it seems it would fit. To your point, the new hook seems no "sharper" than the old. I assumed that its length, though, would be slightly longer, engaging the casing rim deeper. That the old one had worn down a bit, and slipped past the rim instead of grabbing it during the extraction cycle .
I separated the trigger section and set it aside. The breechface is anything but a flat plane, and I cannot deterimine its condition. Two different rounds manually dropped into the breech went in smoothly, and though they both caught just a little as they seated fully, they both withdrew smoothly as well. Of course these were not recently fired casings.
Thanks again for being quite obvioulsy the perfect person to have reached about this problem. I will not try to change extractors without a little more thought.

Do you think a thin coating of oil in the breech, to see if the next dozen or so rounds extract without issue is a sound idea?
There are never ejection issues, only extraction. The casing sits fully in place, and I assume the extractor has simply slipped past the riim. The current extrator seems to move freely under spring tension. I checked for grit that might have caused binding.
As for polishing and borescopes, it sounds like I should change the extractor, and if that does not help. take it in to a gunsmith.
Thanks again...
