Ok so i finally had to do this and noticed there was no tutorial on it, so ill write one, enjoy. It's acctualyl really easy.
dissasemble controller then flip it over so your looking at the board like this.
You then need to pry apart the "arm" that connects the trigger to the actuator (the black thing) fromn the trigger itself, it will come apart, but it will need a little persuasion.
The arrows are to show the direction you should pull the parts
one youve dont that it should look something like this, you need to persuade the trigger past the next plastic parts, again the arrows are to show direction, once you do this it should look like the 4th picture.
once youve done that just remove the spring (carefully so it doesnt fly off) and then you should be able to wiggle the trigger away from the board.
Viola, youre done, to reassmble just do thiese steps in reverse.
hope this helps some people.This post has been edited by grim_d: Feb 26 2008, 02:56 PM
