    Marlin 80 problems

    I have an old 22 rifle of my fathers, the Marlin 80-DL that is a magazine felt bolt action 22. From what I can tell, these rifles were made between 1940-60.

    We are having problems with the bolt. (Please pardon any ignorance on the functioning of normal bolt action rifles -- this is the first bolt I used).

    When lifting the bolt lever from its rested position it "cocks" the hammer of sorts at the rear of the weapon. Pull the bolt back, it clears spent cartridge. Push bolt forward, new round in chamber.

    Oftentimes when pulling the bolt backward, the rear of the bolt (hammer?) will wall forward off its ledge on the bolt and slide down the ramp into the "fired" position. when this happens, the bolt will not proceed back into battery but stay pretty much locked back in the rearmost position the bolt can be. I have to then clear the bolt from the rifle, and manipulate the bolt's "hammer" back onto its ledge. I can do it without tools now, just by pulling it with my hands.

    This has gotten to the point when firing that after firing the round, you have to nurse the bolt back slowly and actually knock the spend casing from the front of the bolt (the bolt still holds onto the casing, it just is not enough force to clear it from the weapon). When cycling the weapon in a faster motion, the spent casings clear fine, but the "hammer" problem with the bolt occurs often.

    From the looks of it, I don't think the spring inside the bolt has been replaced ever. There is no abnormal wear that I can see on either the bolt, "hammer", or the ramp that the "hammer" rides down to fire the weapon. Does anyone have any ideas as to how we can get our Marlin running smoothly again? Again I do apologize for my lack of lingo in this thread, pardon my newbish ways! I have also enclosed a picture of the bolt to describe the function.

    Thank you very much for your time!

        on mine the rear of the bolt has a little shelf for the striker to rest on make sure your is slightly angled to trap it in place

        also make sure your trigger goes all the way foward nearly to the halfway point in the trigger guard if there gets some crud in there it could cause it to not catch the striker as you close the bolt

          Thank you bohoki!

          I know its hard to tell through the pictures, but does the shelf on my bolt look like it is big enough to hold the bolt? I'm willing to buff/grind the ledge a little more if needbe. I will definately clean any snot out of the trigger group.

            gee i didnt even notice you had a pic

            yours looks fine it just looks like it is not sitting in the shelf properly maybe use a little grease on the area will help it sit in that little notch better

            at least it is easy to recock kind of like when a nagant misfires you just pull the area back while rotating

              I cleaner the trigger group.... there really isn't a lot to clean in there... spring and a lever. I also noticed some gunk around the end of the bolt (there seems to be a sort of collar sitting inside the bolt where the ramp goes down to fire) it was very old grease. I will grease it real good with some new stuff and see what happens. It doesn't do it everytime, but you still have to baby it.

              Improvement!

                The more I have cleaned it, the more I am beginning to think its the "ledge" the bolt hammer sits on. I have added two more pictures to show you.... The outside diameter of the ledge is intact but the inner part is tapered inward... thus it can hardly stay cocked now.

                  whoa something is wrong in there if the striker is going beyond the open point i thought it was just rotating over to the "fired" position not rotaing the other way thats weird
                  i would consult a smith

                  well actually i wouldnt i would mess aroud with it til it was good and broken then sell it as a fixerupper at a gunshow

                  but you should go to a gunsmith
