I have a Tikka here in the shop for rebluing and need to take the bolt apart. Can't remember how and don't have the instructions that came with it. If I turn the shroud clockwise, only the shroud comes off. What next.

Jim, this is from their web site:

BOLT DISASSEMBLY AND REASSEMBLY
Generally, disassembling the bolt is not necessary. But if you have reason to believe
that oil may have penetrated the bolt, you should clean it in order to retain
its smooth operation. This is particularly important if you use the rifle in cold or
harsh weather.
In order to disassemble the bolt, please follow these steps:
1. Carefully check that the rifle is unloaded and remove the bolt from the rifle by
pressing the bolt-release lever on the left side of the receiver.
2. Remove the bolt shroud by turning it clockwise until it stops and pulling it away
from the bolt.
3. Insert the tip of a screwdriver (approx. 3mm wide) into the gap between the
cocking piece and the bolt handle retainer bushing. IMPORTANT! Do not remove
the screwdriver tip from this location until you are ready to reassemble the bolt
shroud.
4. Disengage the firing pin assembly by turning the screwdriver counterclockwise
(see fig. 11). Push the firing pin assembly forward until the locking cam (E) of the
handle retainer bushing touches the bolt’s rear surface.
5. Release the bolt handle from the bolt body. If the bolt handle feels stiff and
does not immediately pull out, you can tap it with a plastic mallet at the receiver
end (arrow G).
6. Remove the firing pin assembly from the bolt.
The bolt should not require any further disassembly for cleaning purposes. In order
to reassemble the bolt after cleaning, reverse the order:
1. Push the firing pin assembly into place. Make sure that the bolt handle retainer
bushing is in the correct position, so that you can ease the bolt handle back into
place without obstruction.
2. Reassemble the bolt handle to the bolt body.
3. Re-engage the firing pin assembly by turning the screwdriver clockwise as far
as it will go. Make sure that the retainer bushing locks the handle.
4. Replace the bolt shroud by turning it counterclockwise until the cocking piece
cam stops in the notch (D) before the cocking slope (see fig. 2).

English part is about 1/3rd way down. Several models listed so you may want to check.

Sorry Jim. But that's probably how I would do it if I ever need to. Thanks for the info Thaine!

Aha!!! That little tab and the screwdriver, now I remember. I am diminished. Thanks.
