Help with a 1903a3 bolt
Hello,
I have a sporterized Remington 1903A3. I disassembled the bolt for cleaning (have done this before w/no problems), when I reassembled the bolt was almost impossible to cock. I had to pull the the firing pin back in order to cock the bolt. With it engaged it worked fine. Thought it may be a bad spring so that was replaced. Same problem, any suggestions?
Thanks,
Dale

Hard to tell. Here's a video to watch to make sure you didn't forget something. This link is to the re-assembly video. Same guy has one on dis-assembly.http://www.youtube.com/watch?v=48wNQ...eature=related

Mike,
Thanks for the clip, but I've already checked it out. That's were my confusion comes from, it's a simple reassembly- only took out firing pin, spring, and safety (beuller). Disassembled/reassembled several times. It's like there is too much tension on the spring???

Is there any wear to the bolt sleeve where the cocking piece contacts? Maybe the bolt is binding the receiver somehow? How are the bolt lugs? Do you have another bolt to try? Maybe another bolt could narrow it down?

Outdoornut,
You didn't by any chance install the striker sleeve upside down, barrel side goes over the bottom of the striker.

There isn't abnormal wear. It was working- took it apart to clean and the stress on the bolt was amazing. I have to pull the striker to work the bolt.
I will check the collar again-I'm at work right now, but am 99% sure the knurled end is down as in the pic (thanks Dad). I actuall cut the spring in 1/2 to make it work. That is why I thought it was a bad spring. When I replaced it- same problem. This really seems like a reassembly problem but it's so straight forward I can't see what could be wrong. The only thing I didn't do is when the bolt was replaced I move the cut off switch to 'on' instead of 'off'. I am truly stumped on this 1????

ODN, if you had to cut the mainspring in half to get the bolt back together it sounds like the firing pin wasn't all the way forward. Note: in the video clip, at the start of reassembly, the narrator flips the safety to the fire position and inserts the firing pin in the bolt sleeve. The knurled knob of the cocking piece is almost touching the back of the bolt sleeve. If, in your case it is sticking out say an inch or so then something is preventing the firing pin from going in all the way. I suspect it might be the Buehler safety.
If you have a GI safety around try reassembling the bolt with the GI safety in place.
Good luck!
Regards,
Jim

I've tried it w/out the safety and still under alot of tension. It has to be the wrong spring. I've ordered another spring from GPC and the original safety. Hopefully that will do the trick. I:banghead:

Do you have another bolt to try?

When reassembling the bolt;
First. Move safety to "FIRE" and insert firing pin into bolt sleeve.
Second, slide mainspring onto firing pin.
Third, Press cocking knob against table and compress mainspring using the striker retainer.
Fourth, slide the striker onto the firing pin.
Fifth, Let the mainspring come forward slighly. the larger, cupped end of the retainer will lock the striker.
Sixth, Grasp the assembled firing pin in your left hand pull back the cocking knob with your right and use thumb to flip the safety lever to 12' oclock.
Seventh, Screw the assembled firng pin inot the bolt.. depress the bolt sleeve lock and turn bolt sleeve until it clicks.
That should do it. From reading your description I was wondering if you perhaps were installing the mainspring BEFORE inserting the FP in the Bolt Sleeve???
The only otherthing possibly worth checking is to make sure the FP slides easily backand forth in the bolt sleeve. Any binding may indicatea bent firing pin. i would discount dirt or corrosian if you just cleaned the parts.
Let us know how you make out.

Jim
