There is absolutely no force necessary. Hold your bolt carrier in your left hand, breach face facing to the right. Apply pressure with your left thumb on the extractor. With your right hand, use a small punch to push the long pin you see in the instructions posted in post 1 from the bottom of the carrier out towards the top. No punching is necessary, just pushing. Remove the long pin. Now slowly relieve the pressure on your thumb and the extractor and its spring will come right out.
The extractor springs rests on the fat FP retaining pin/block. Apply a little pressure to the firing pin and using a small punch push the fat FP retaining pin through the small hole on the opposite side towards you. If you were now to relieve your finger pressure on the firing pin, you'd notice it will stick out farther now, but not come free. Put your finger back on the firing pin. Depress the firing pin block plunger, which will free the firing pin and let it slowly come out. Once removed, you can also pull the firing pin block plunger and its spring out.
Reassemble in reverse order. Note that the firing pin has to be reinserted properly oriented, such that the FP block and the FP retaining ping can sit in the grooves. Also, as mentioned earlier, when you reinsert your extractor and hold it in with your thumb while pushing its retaining pin back in from the top of the carrier, it might be difficult hitting the hole. I used a small punch from the bottom of the carrier to help align the extractor with the hole and then pushed the retaining pin back through. You gotta wiggle the extractor a bit until the pin slips through the hole.
Again, no force necessary in any of these steps, provided you use your thumb/finger to put some pressure on the extractor and the firing pin to relieve any binding pressures caused by their respective springs.
I'll see if I can make a small video. It's a really very simple and quick procedure.
