Mosin Problem

[Cosmoline]

I've run into my first major parts-related problem with a Mosin. I have a nice Tikka M91 but the extractor claw is on its last legs. It works OK, but is pretty weak and looks to be about 100 years old. I have several brand new ones around so instead of waiting for it to break in the field I decided to remove it. But it won't budge, because it's been in there for a century and has been rusted over and cleaned multiple times.

Then I had the bright idea of intentionally splitting the top part off so my pin would have direct purchase on the base. Then I figured I'd be able to pound it out in the vise, no problemo.

Well the problem is, I can't break the dang thing! I've tried hammering it and using big pliers, but it keeps bouncing back and won't even bend out of shape.

This thing is terrible.

Get a new bolt face if nothing else works. Actually get like 3-4 due to head space problems.

try freezing the bolt, shouldnt be a problem up there in Alaska. then using some form of direct heat (soldering iron) to expand some. just an idea

I'm with Hoppy590 but in my experience you may not need cold temperature. Usually applying indirect heat with a propane torch or Bunsen style burner will be everything you need. Whatever you use, make sure it has adjustable gas levels and an adjustable torch/flame. Make sure the flame is blue with no flickering of any color or sort. If the flame is red/orange it will leave carbon deposits on your metal and potentially damage it.

After applying some heat to it, try a hammer and punch. Should come right out, but if it doesn't be patient. You can do more harm than good if you rush it. I had a similar problem with a stuck bayonet on my 91/30 and nearly ruined the front sight.

Look about midway down the page to see how to remove the extractor. You have to drift it out with a punch from front to back.

Cosmoline,

Are you SURE you don't want me to send you some Kroil?

 

[Cosmoline]

LOL Maybe we need to set up a kroil for the needy charity

I meant to say bolt head.
