It's not that hard.
To remove completely, below the playfield clip a cable tie or two and unplug a few connectors and three opto connectors coming through a hole below the black pearl. Skip that part to lay it on it's side on the top side of the main playfield, put something down to protect things, like a towel.
Lift playfield up and pull forward and rest on front of cabinet. Behind playfield pull the metal clip off, slide flat metal thing that connects the motor to the black pearl off, and remove the big fat white nylon washer and set somewhere safe.
Between the black pearl and rear wall of the playfield look down, see the 1/8th inch allen head screw - remove it. Grab the black pearl, one hand each side and slide towards rear of game, clearing the two pivot points and lift the whole thing up.
Reverse procedure to put it back in.
