Mosin 91/59 - looking for info

[Catt57]

Ok, got it broke down and cleaned. Dirty but not to bad. Still has some cosmoline in the stock. But I did run into 1 issue. I cannot get the cocking knob to unscrew from the firing pin. It's locked on tight. I have an extra pin, spring, and cocking knob so if I have to do something drastic like drilling it out I can but does anyone have another idea?

Try soaking it some PB Blaster, Kroil, or other penetrating oil for a day or so.

Just got back from the range. It kicks like a mule and has a flash brighter than the sun. But man is she accurate. Standing @ 25 yds 1.5" 5 shot group, and I'm positive it's more accurate than I am.

First shot and the entire firing line looked to see who had the cannon. Well that and I think I blinded everyone with the flash....

Oh and here is my friend shooting the 91/59. Now THAT is a flame thrower.

OK, soaked the bolt in PB for 2 days, no luck. Tried carb cleaner, no luck.
Still works, but will not separate. Afraid I may have to drill the firing pin out....
I do have a spare firing pin, spring, and cocking knob so I can reassemble if I do need to go that route.
Or should I just work a little oil back into the assembly and leave it be for now?

This is a version of "if it ain't broke, don't fix it". If the reason you want to separate it is just because you don't like to be told you can't, then there's not much hope for you. Go ahead and have at it. However, if you are happy with the way it shoots and performs, why not shoot and enjoy? As you might guess, I say "let it be". You can always mess it up later.

+1 for leaving it be.

Take the bolt head and connector off, blow out any penetrating oil that has seeped inside, reassemble, check your firing pin protrusion...if it's in spec, call it good.

 

[Catt57]

My main reason for wanting to disassemble it was to get it all polished and remove the tarnish.

 

[Catt57]

So I did finally get the bolt apart. It took a vise and a pair of pliers to get the firing pin unscrewed. Turns out a previous owner cross threaded the firing pin into the cocking knob. (How they did this i have no idea.)

Luckily I have extras of both. After replacing the parts, cleaning and a very light oiling the bolt now moves a lot easier.

That would be pretty difficult to do. Glad you figured it out.
