bolt body schematic

[ground ape]

Hi all, Will someone please get me a drawing for a 91/30 bolt body? I think I have excessive wear. Thanks Chris

I'm pretty sure there's one on 7.62x54r.net......SBP

Thanks SBP, I have been through that site. My quest begins with a locking bolt problem. I boiled the action for half an hour and that had the lugs engaging and disengaging just fine but the bolt, unless cocking first, requires mega force to get it open. Next I sanded and polished the cams, still no joy. Then I noticed what I thought might be excessive wear on the opposite side of the bolt handle running down to within three quarters of an inch of the end of the body by a half an inch in width. Looking at the front end of the bolt body the wear point has the opening perfectly circular but the outer profile is decidedly egg shaped. I want to know if this is excessive wear and could it impact my locking bolt problem. The bolt shows signs of long use and hard use. Thanks. Chris

Your problem is most likely not with the bolt body or bolt head. The problem you describe is a common one caused by a dirty chamber. Inspect the chamber for dried grease or 70 years of just plain crud. Have you checked the headspace? Sandpaper has no place in fixing this problem. Search the forum posts for, "sticky Bolt", problems.

I believe the one hour boiling the action in water with following scrubbing with solvent took care of the chamber. When the action is closed it is opened easily on cocking leading me to suspect the opening cams as suggested on the net. BTW the sand paper was actually emery cloth and that was followed by Tripoli giving a fine polish. I am beginning to think the bolt is excessively worn and binding when turned. I am looking for a pic of the front end of a bolt body to compare.

If the bolt itself looks abnormally worn I would suggest acquiring another bolt for comparison; Or, if you have multiple rifles test swap another bolt to see if that rectifies the issue.

Good Luck!

Thanks Rongo, I am about to order an "excellent" bolt. I am happy to spend money on this gun because it is pre-war build, just, 1940 Tula with "accuracy barrel" and a great bore. Might even go for the Timney trigger. Or maybe another $169 Mosin. Or both. I think its taking over, Cheers Chris

You will have to "aler" the rifle to put a Timney trigger into it. The collectible value will drop dramatically. We usually don't discuss this on our "preservation" forums.

That will be noted and complied with to the letter. I realise that there is more than a dollar value in play here and I am fully supportive.

It sounds like maybe all you need is a bolt head...... SBP

Hi SBP, After a 1 hour boiling of the barreled action in water and a chamber scrubbing with Gunslick solvent the bolt head turned easily. I polished the cams mildly with no change. In the near future I will buy another 91/30, this will be examined thoroughly and from a more informed perspective. Oh yes it will. I will also buy a VG bolt from a dealer. I can't wait to see how this rifle does as the bore seems to be in great shape, it cleaned up well with boiling water and solvent pull through swabs. Thanks for your interest SBP, Cheers Chris
