Reassembly in reverse order. After reassembly, the firing pin protusion should be checked with the firing pin gage tool. The tool have 2 notchs marked 75 and 95 but some tool dont have number. Usually, the deepest notch(95) is used for checking.

The Mosin bolt is a bit of a Rubics cube the first time taken apart and put back together. Its always a good idea to print off an article such as this to have it next to you when disassembling the rifle to keep the grease and dirt away from your keyboard and computer room. I have a print of instructions for every rifle, that I keep in the gun room in the shop for this very reason.
