Hey Guys,
I seem to be having a problem with my mosin nagant 91/30 ex-sniper bolt. It refuses to be reassembled. I have had this problem occur every time i reassemble the bolt. The particular part I am having problems with is when you are trying to attach the cocking knob to the firing pin/spring in the bolt body. This part of the assembly has been giving me problems since day one and after trying today for several hours, I still dont fully understand how to reassemble the bolt. I have tried using a hard surface and then pushing the bolt body with spring and it only reaches the bolt body entrance, but does not go past it no matter the force applied (Fairly big guy 6'1 200+). Ive even tried the multitool approach and it worked once and sadly didnt this time. Any one else have this type of issue?

Curtton is gonna lose it! Your Done! Banned! :p I'm just kidding, I havent done a Mosin bolt for a while But I remember placing the bolt face down on a hard surface and pushing down on the bolt handle to push the FP out the back of the bolt body. Then just thread the cocking piece on until the FP is flush. I'm pretty sure I had the bolt head and connector bar removed while I did this.
 
Okay if you are starting with your bolt dissassembled and I'm going to describe it with little steps so you can have multiple ways for confirming you are on the right track.

take the bolt body (big thing with the handle for operating bolt when shooting)

Then find firing pin and put the spring on the firing pin.

Once that done, slide firing pin into bolt body.

Then: turn the whole thing upside down so the firing pin tip is pushed against the floor, or any wood surface you don't care about. (good idea for it to be wood so the pin doesn't slip)

Push down on the bolt so that the firing pin withdraws into the bolt body as far as it goes. This should compress the spring and make lots of spring tention and that is why you must use your body weight on the hand that is pushing down on the bolt. The hand applying the pressure on the bolt should be gripping the bolt body by the bolt handle (thing you use for cycling bolt when shooting)

Next: use your free hand to put cocking nob on the top of the bolt (opposite end from the firing pin tip) Thread the cocking peace on until the rear of firing pin is flush against the cocking nob.

(If this last step is not working then you must make sure you are pushing down on the bolt to compress the spring and keep the firing pin as far into the bolt body as possible)
BE SURE YOUR PRESSURE/WEIGHT ON BOLT BODY IS CONSTANT during this hard step

I remember being taught the cocking nob usually requires 3 revolutions when being threaded on.

finish with the cocking nob in the position of when the rifle has just shot before you cycle the bolt to eject the brass.

Once this is done, look at the firing pin and notice how 2 sides of it are rounded and the other 2 are flat. This is on the section of the firing pin before the tip. Aline the flat sides so they are parreleling the bolt body's face where the bolt head's lugs lock in. You can turn firing pin using the screw driver and turning the screw in the cocking nob.

I hope this was helpful and set you on the right track. I am sorry if I confused you more as this is my first time writing something like this out.
 
Hey Guys,
Thanks for the replies. I managed to find out what I was doing wrong. I had previously had the same problem, but could put it back together. The main problem was when pushing the bolt down for putting on the cocking knob, but it seems i was pushing it at a slight angle, which resulted in it not going the full way down. Now that ive fixed that it appears to do it properly more often. Thanks again :).
 
Last time i disassembled my mosin bolt, i needed both hands and my right foot to hold the bolt handle while strongarming it back together. Some would say a third hand would help, but if you have long prehensile toes like me it's easy!
