The question of 'how to remove and/or install the extractor, its spring and the detent ball has been asked around here several times as of late, so I grabbed up my camera and figured I would see if I could help out. Follow along as I explain how simple and easy the procedure is.
Here we see the bolt head fully assembled and ready to use. Note: this is a 1970's era 30-06 bolt head, and yes the machining of the face is a "bit" rough. But I have used this head and the roughness seems to have no effect on the brass.
To remove the extractor, place your index finger on the outside of the bolthead (at the orange arrow) and apply pressure with your thumb pushing from the green arrow towards the orange arrow. Going very slowly you feel a light click as the extractor pops over the detent ball underneath.
Keeping a light pressure with your index finger (as shown) and your thumb still over the inside edge of the extractor and covering the ball detent, you can slide the extractor out (away from the orange arrow) and slowly lift your thumb off the bolt head easing off the pressure of the spring that is under the ball.
Now with the extractor and ball removed you can see the spring inside the bolt head as indicated by the orange arrow. Use a small dental pick, knife point, or other pointed object and simply pull out the spring.
Here we see the spring removed as indicated by the orange arrow once again. It is a good idea to clean any debris from this blind hole using an aerosol gun/parts cleaner. Use proper eye protection and have adequate ventilation as cleaners often tend to release fumes.
