Tikka M55 bolt disassembly and reassembly

Post by Tikkafan » 30 Jun 2026, 4:36 pm

Hi Everyone,
I want to disassemble the bolt on one of my Tikka m55’s and was wondering if anyone could explain to me how to go about it and also if there any exploded views of the bolt available as I haven’t been able to do so?
Thanks

Do you really NEED to? Or is this just a fancy to see and clean? I ask because it is easy to disassemble but not so easy to reassemble, requiring the firing pin spring to be compressed and then turned after compression. If you actually need to do this then look up Ithaca LSA 65 bolt disassembly, the tool to reassemble can be made simply from a block of hardwood with a hole for the cocking piece and a slot for the sear (looks like a keyhole) and you assemble the bolt upside down ie: cocking piece in the hole with firing pin pointing up, push body down over the assembly and twist. There were instructions on the sakocollectors forum a few years back. I will post an exploded view of the rifle shortly, take me a few minutes to find it.

If you have access to a vice mate, and have a good look-see first, you'll find it's easy. I did anyway.

It was for a mate's M55, I had a look around the internet and YouTube and couldn't find anything that helped me.
Once you've done it, you'll see what I mean, you need three hands. Hence the vice, the way I worked it out at least.
There might be some tool that helps. I know with the Sako's of the last 10 years at least, they give you a tool to do it in the box when new.
