Bolt Disassembly Help

[Arcturus41]

Hello everyone, I bought a Spanish 1916 Mauser recently and am in the process of taking it apart and thoroughly cleaning it.  It's a cock on close bolt.  There's a whole bunch of gunk in the firing pin assembly.  I've looked up online how to separate the firing pin from it's housing thing, yet it isn't coming apart.  I've depressed the spring and turned it yet it won't come out.  I've spun it a whole 360 and tried to take it out with no luck, and I haven't found anything on the internet about it.  Do you guys have any suggestions?
