It is a matter of taking the halves apart by removing screws, and having a good schematic to go by before you start. Taking photos is not a bad idea!

The parts simply unplug and re-plug to replace them. The beam type spring on the front of the drill that provides the detents for the torque on the screw drive function fell out and it wasn\'t clear how it went in (it slides into a groove on the left side) from the drawings.

Be very cautious with small parts/springs because they can shoot out of there holders.
