take off grips
undo frame screws, and screw in breach front (where barrel threads are)
ease apart
undo the front banjo hose and back banjo hoses
ease apart some more and tilt away from frame
the board slides up from the frame, it isnt screwed in.
remove the eye wiring, and it should all come out, so you can fix it.
this is from memory of about a year ago but should provide a start.
