I still come back to this. Quality stuff.
Excellent video & instructions. Thanks!
Very good, thanks for the walk through on disassembly!
Thank you …. I have a 1976 336C and this video is essential. Very grateful. Thank you.
Great video. Helped me immensely. Thank you.
Thanks for the knowledge, Sir !!!!!!!!!!!
Excellent video, thank you.
Very good instructions thank you. I used your instructions for a Marlin Model 30AW. The only difference was that on my gun the roll pin lengths are the same.
Thanks!!! I'm rebuilding a glenfield 30a barn find.
thanks bud. great video
Excellent video great narration!
Great video, thank you!
Thx. Good work.
Thank you.
Good lesson
thank you
I have an 1895 marlin is it the same procedure , thank you, instructive and clear .
Excellent video, thanks. I don't suppose these parts need maintenance? A spray of oil to keep them rust-free will suffice until a parts failure?
Khethatipet Thanks for the comment, and yes light oil...you can download the manual at Marlin’s website and it will give you the exact lubrication points
Does the flat on the roll pin (slot) face the firing pin when reassembling
Do you have any suggestions on what may be the issue if the rifle is prone to light primer strikes? The bolt was disassembled and reassembled to factory standards, with no damaged components. I'm thinking that the leaf spring might need to be replaced. Thank you for the video.
Arthur, get a can of brake cleaner (go outside to do this) and after taking the bolt completely apart again, spray the cleaner down through the bolt body for a good cleaning inside. Let it dry or use compressed air to blow out the bolt body. No oiling the inside of the bolt but you can oil the firing pin ever so slightly. Reassemble, test fire. If problem persist, idk.
The leaf spring is what pushes the rear firing pin down at an angle and out of alignment with the front pin. It’s part of the safety design. There’s another part, not shown in this video, that rises up when you close the lever. That part pushes the tilted rear pin upward into alignment with the front pin so the rifle will fire. The leaf spring is compressed when the rear pin is in alignment. Unless the leaf spring is in pieces, it shouldn’t affect primer strikes.
Three easy things: make sure your hammer spring is full strength. If it’s been swapped for a lighter spring, go back to factory. Then no lubricant, dirt, rust, etc in the firing pin channel. Don’t put lubricant of any kind where it could get in there. The firing pins must move freely except for very light dragging of the rear pin against the leaf spring. Then try non-Remington ammo. Lots of reports of hard primers.
Please don’t have any ammo around when working on the rifle. If any of this sounds confusing or unfamiliar, a gunsmith shouldn’t take more than 10 minutes to diagnose, and maybe 30 minutes to get it back into working order unless there’s something catastrophically wrong. But the chances of that are 1 in a million. Go with the easy stuff, because those are the most likely culprits.
Cheap money compared to how long the rifle will last and function flawlessly with just basic cleaning. Good luck.
@@rjohnson5120 good call on using different ammo.
@@easttexan2933 I’m having the same problem with an old 336 myself. Your brake cleaner and no lube suggestion is a good one. Didn’t mean to repeat you, you are right on. Lots of folks with this problem mention ammo. Only problem with that advice is there’s no ammo available to try!
This is an excellent video by the way. I should have acknowledged that because it helped me. My front roll (actually solid in mine) pin was messed up and ancient and it wasn’t clear what I was looking at. Kroil and 10 minutes of careful hammering and it finally budged.
@@rjohnson5120 excellent
I somehow can't get my rear pin out. I've beat the everloving crap out of it and it refuses to budge. Soaked in in every penetrating oil I have. Mine are the old school solid pins, not the roll pins.
Didn’t say to clean inside of bolt, and clean firing pin, and leave it dry, oil in cold weather can slow pin travel and causing misfire.
Yeah, just a disassembly/assembly video. Thought about doing maintenance videos but everyone has their own way of doing things.

Why does rear firing pin angle down?
A small leaf spring presses it down. It is apparently a safety feature that prevents the firing pin from striking the primer when engaging the lever.
