Re: how to disassemble and clean springfield model 67 series e 12ga. by savage arms
Parts number 31 and 33 govern the bolt locking. When the bolt closes, the bolt lock raises up to the rear of the bolt locking it in place. When the gun fires, the hammer comes forward and the small stem on the side of the hammer catches part number 31 (spring) and pulls the bolt lock down to release the bolt for the next "pump" loading. The "nose" of the bolt lock most times wears or deforms due to repeated battering and has to be reshaped, tig welded and refit or replaced. While replacment would seem the easiest to do, most times it isn't. The hook spring on the bottom of the bolt lock has to be in the proper position for the hammer to catch it in it's forward travel. Going to a new bolt lock will require you to guess repeatedly at the proper amount of "bend" it has, and exactly where. A good idea would be to make a tracing of the bolt lock on paper of the lock and spring unit to refit the new parts. If you MUST replace the parts remember that while the system might work well while you have the trigger group in your hands and the hammer catches the spring to release the bolt lock, when you install it in the rec the lock will not come up as high as when it was in your hand therefore putting the hook spring in a different place when the hammer falls. This caused me considerable consternation when working on these guns untill I figured out the error. When disassem for cleaning, it is best to remove the butt stock and the small thru pin is easier to drive out from one side more than the other (I don't remember which at the moment). For cleaning I would soak, brush out, blow clean and oil rather than dissem the entire trigger group unless you have more than average experience with guns. When the bolt does not come forward enough to fire, check the chamber area, bolt face, extractor slots for anything that could retrd forward travel. Also see if you can make another turn on the forend cap (aafter cking to see that your pin is not worn or broke). Good luck.
