Once again I grabbed up the camera and snapped some pics to demonstrate the installation of the Ejector assembly. And of course by reversing the procedure you can disassemble as well. Let's get started.
Here we have a bolt head with the Extractor installed, but void of the Ejector parts. Note: always a great idea to clean the Ejector's blind holes with a little gun or parts cleaner. Of course wear eye protection and do in a ventilated area as cleaners often emit fumes.
Next we need to insert the Ejector Spring into the blind hole. Note: I left this spring sticking out a bit for illustrative purposes. Normally the spring will be below the face surface of the bolt head when fully inserted.
Now we are going to insert the Ejector Plunger into the blind hole. There is a flat machined into the side of the Plunger, the flat is closer to one end than the other. The "shorter" end needs to go into the blind hole, with the "longer" end sticking out.
Now, take the Retaining pin and start it into the hole on the side of the bolt head. I am showing it here starting from the side with little flat machined into the bolt head, but some bolt heads allow the pin from either side, and some just from one side or the other so some experimentation on your specific bolt head may be required to determine which direction works best for your situation.
Now with the Retaining Pin started (shown by the green arrow) and the Plunger started (purple arrow) it is important to have the Plunger indexed so that the flat on its side is facing the Retaining Pin (orange arrow), otherwise the Retaining Pin will not go into it's blind hole due to making contact with the Plunger itself.
Now with the Plunger indexed properly, I like to use a piece of fired brass and push the Plunger and Spring down into the blind hole. Once the brass has reached the bolt head's face, the Extractor will hook over the brass' rim and thus allowing you to hold the brass as pictured. This allows you to easily keep the Plunger and Spring depressed. Now, hold as shown, just take a small hammer and carefully drive the Retaining Pin (red arrow) into the bolt head. Note: Be careful as the pin is of small diameter and will bend easily. Careful easy strikes with your hammer is all that is required. If it does not go easily recheck all parts for proper alignment as shown above.
And here is the bolt head with the Ejector and Extractor fully installed and ready for re-insertion back into the action.
For ejector assembly removal just reverse the instructions above. Be sure to use the proper size punch to drive the Retaining Pin for its blind hole, and often factor installed ones prefer to be pushed from the top of the head towards the bottom ( the bottom is the side with the small flat machined into it).
Also, if you are trying to remove a retaining pin on a bolt head with the ejector stuck in the down position, especially due to a blown primer, soaking in Kroil is a great way to help it loosen up. Also in some circumstances the retaining pin will actually get bent internally and jam internally causing the plunger to get wedged between the pin and the bolt head itself and often times are a real pain to remove. There is no sure-fire way in that situation, but Kroil is a great start.
