K98 Bolt Disassembly

[alanten]

Taking apart my new to me K98, one of the Portuguese contract ones from Centerfire, and need a little help with the bolt. The first part of the process was easy: flag up, bolt out of the receiver, then depressing the catch to unscrew the firing pin assembly. I ran in to trouble when I tried to insert the pin in the bolt disassembly hole and compress the spring. I was pushing the piece down far enough, but could not get the top piece to rotate so that it would release and the spring could be removed. I apologize for not using the correct terminology, and would appreciate any corrections, as well as suggestions on how to get it apart. Thanks in advance.
