Step 3 is incorrect. The only things keeping the internals secured in the casing are the two ‘elbows’ clearly visible in Step 3 picture 2. Simply pry these away from the depressions in the casing and the works slide out, with a little push from the top stem. The method describing the 3 red clips does no good (besides being nearly impossible to accomplish) and presents a clear risk of breaking the hair-thin wires

The method described in Step 3 to remove the internals from the casing is incorrect. Rather than prying the 3 red clips (nearly impossible anyhow) all that is required is to pry the two ‘elbows’ visible in step 3, photo 2, away from the depressions in the casing. Voila.
