The DVD goes into great detail showing you how it works. I show how it works when it is out of the machine and also when it is in the machines as well as how to properly install it in the machine.
There is an arm which holds the reserve in place. After the jackpot trips and during the next cycle this arm moves backward (if facing the front of the machine) which allows the reserve door to open. On the next pull another lever is triggered which forces the reserve door to close and lock into place.
As far as how many pieces, I have never counted them and I don't have a jackpot torn apart right now to count them. I think the YouTube link on the web page I referred to shows all the pieces on the work bench.
Not sure why the img tag is not working for you. Are you including the entire URL in it?
I will send you a private message regarding the other stuff.
