Carcano Bolt Will Not Disassemble

Post by Phantom 778 »

I have a Carcano M91/38 TS. My wife and I recently aquired this rifle so we are still doing our initial inspections. When attempting to disassemble the bolt by pressing down the stud on the cocking piece, the stud stayed down. I assume this may be due to rust. Also, the cocking piece will not come off so any further disassembly is at a total stand still right now. Any ideas on how to fix this problem? (I am just soaking what I can in Gunzillla for the time being). Thanks

It definitely looks like rust. I had to go to YouTube as it's been years since I took my m91 carcano bolt apart. I don't recall that I removed the nut on the rear. I recall just removing the cocking piece and then the rest of the parts. But I could be wrong. Or the bolt wasn't put together right when I got it.
Like this video shows there is a slot on the firing pin which must line up..
Good luck.
Let us know how it goes.
If you are still stuck someone more knowledgeable will show up.

So I was finally able to remove the cocking pieces. Looks like the Gunzilla did the trick there. I still have a problem though with the button on the cocking piece. It is still stuck in the down position. Any ideas on how to pull this back out? There is nothing to grab onto. The button in flush down.

More gunzilla, perhaps boiling and taps with a hammer. Taps not strikes. 😁
If I recall the detent is held in place by a pin, perhaps you can tap that out and get some more oil in there.
I have not used gunzilla, but have used pb parts blaster with good results.. kroil is also said to be excellent.

Thanks for the tip on looking for a pin to punch out! I didn't even think about that! I will look into this!

Kroil & some Kerosene mixed together 50/50. Let the piece soak a week. PB blaster tends to dissolve the rust. Use a fine brass or steel brush to get the surface rust off. PB Blaster really stinks, but fill a baby food jar from a spray can and let the cocking piece sit a week. Wire brush the lose rust on the top. Every day push it in and try to tap it so it moves in or out a wee bit. If it pushed in, it should work free-- Time is you partner. After a week in PB Blaster, then use Kroil and Kerosene. Heat with a propane torch may also help you work it free. It is possible the tiny, thin, spring has rusted away or split and no longer has tension, hence it no longer functions. :confusion-questionmarks: That's how you spell screwed & buy a replacement part. Easy fix. If you are in a hurry, just buy a used replacement part ( just be sure it is not stripped). libertytreecollectors :arrow: https://www.libertytreecollectors.com/p ... ategory=28

Mine did the same and I took some Simple Green and soak it then a plastic hammer for persuasion. gently? Still pretty hard going.

I have taken apart three Carcano bolts but the latest is causing issues. I can’t get the threaded nut off. Bolt works great and I have even shot it this past a Friday. However I did want to take everything apart. Any ideas or leave it be?

I have been working on a 91/24 that the bolt cocking piece refused to come off until I used a screwdriver to pry it off? It had a burr on it and just wouldn't move.

I'm a very stubborn personality and have even been known to lose some sleep brainstorming such mechanical problem. With that being said, I would most defiantly attempt to separate the threaded nut. However, ATTEMPT is a keyword. If the rifle is functioning fine and your attempts are unsuccessful, even I would eventually claim, "if it ain't broke, don't fix it." But I would at least try. Have you tried using some good'ol fashion penetrating oils to help break up whenever it is seizing up the threads?
