Hold the bolt in your left hand, press the bolt sleeve lock in with thumb of right hand to unlock bolt sleeve from bolt, unscrew bolt sleeve by turning it left, you may have to pull back on the cocking piece while turning the bolt sleeve in order to completely unscrew the assemblies.
At this point you should set aside the bolt and can disassemble the firing pin mechanism, the firing pin itself has two parts, the pointed part that strikes the primer and a sleeve that locks the striker to the firing pin rod. Carefully pull at the base of the striker to separate the two parts, continue pulling (carefully as the spring is stiff) until the striker is exposed and you can remove it from the firing pin rod. Slide the sleeve off and remove the mainspring. Once the mainspring has been removed you can slide the firing pin rod out of the bolt sleeve.
To remove the extractor, force its tongue out of its groove by turning it counter clockwise (as viewed from the bolt face) and then simply slide it off the front of the bolt.
Hope this helps, it was paraphrased using my experience and the official US Army maintenance manual.

To disassemble the bolt on a Browning X-Bolt, first ensure the rifle is unloaded and pointed in a safe direction. Remove the bolt by pulling the bolt release lever located on the side of the receiver while simultaneously pulling the bolt rearward. Once the bolt is removed, you can disassemble it by pulling the bolt handle back and rotating it counterclockwise to unlock and separate the bolt body from the bolt head. Be cautious not to lose any small parts during the process.

Highly recommend you ask a gunsmith for assistance.
To disassemble the Cooey Model 60 bolt, first ensure the firearm is unloaded and the safety is engaged. Remove the bolt by pulling the bolt handle fully back and then lifting it out of the receiver. Next, locate the bolt stop and push it down to release the bolt body from the bolt handle. Once separated, you can further disassemble the bolt by removing any screws or pins as needed for cleaning or maintenance. Always refer to a specific manual for detailed instructions.
