To remove the hammers, take the small set screw that holds the hammer pin in position out before driving the hammer pin out. Driving the hammer pin out will leave the hammers still in the receiver and under spring pressure but slightly back from their pivot positions. No they won't fly out of the receiver when you remove the hammer pin. To remove each hammer, take a narrow screw driver and tip the cocking arm (forward extended arm) of the hammer downward (looking at the bottom of the disassembled action) and hold it in that position. Take another appropriate shaped narrow screwdriver (handy aren't they!) and from the back of the action, place that one between the inside top of the receiver and the top of the hammer and gently lever the hammer upwards just a little and the hammer will pop free of the receiver. The mainspring and follower will then be free to be removed from the receiver. What you are doing in all this is rolling the hammer back as in a cocking motion to free the fireing pin tip from the fireing pin hole in the receiver so the hammer can be lifted up and out of the receiver. On reassembly, push the hammer back down into it's position in the receiver once again with the hammer spring guide in place against the mainspring follower. A large blunt wide blade driver against the back of the hammer given a smart shove will snap the hammer back into the position but then you'll need to push the hammer(s) forward just a little under spring pressure to line up with the hammer pin. Replace and tighten the set screw for the hammer pin.
