I need to replace the firing pin in my 1957 Marlin 336 S.C. I doubt the bolt has ever been disassembled as I'm having a serious issue with it's disassembly.
I've managed to get the front pin out with relative ease, however the pin holding the rear firing pin in is siezed in place. I removed the front pin from the bottom of the bolt through the top as instructed in a YouTube video.
The rear pin is what's giving me issues. I've beat the hell out of it with a steel pin and brass hammer to no avail. I even reluctantly used a steel hammer, no dice.
I've soaked it in WD-40 overnight as well as boiled the bolt in water in hopes it would help loosen the pin up.
The front pin doesn't seem to be tapered, so I would assume the rear one would also not be tapered. The pins are solid, however I've seen in some videos that people have bolts with roll pins. I'm curious if my pins are replacements. The seem to be stock and original, but I could be mistaken.
I'm at a loss here, I may just need to drill them out. I'm reluctant to do that until all options are exhausted, though.
