Answers.Text: Indeed it does. Your small part (the one with the white beam) looks like it's mirrored from what it should be. The 11L beam should be on the right side, not the left one.

  Seeing the manuals, I'm fairly confident the instructions are correct.
  
  The 11L beam from the second part (introduced in book 2, p 2, #1) looks like it should slide right next to the yellow gear (thus, not right on top of the right 7L beam (introduced in book 1, p 79, # 4) but one stud to the right, which shouldn't be a problem). To clarify, the 11L beam should be exactly in the middle, at equal distance of both yellow gears, right on top of the part with three holes protruding from the turntable on the right.
  
  I'l admit I didn't build it myself yet though, so maybe I overlooked something.
  
  Moreover, I don't really see what could go wrong, especially in book 2. Even in book 1 I can only imagine swapping the right 7L beam with the other part in #3 of page 79, thus having the two 7L beams next one to another, but that kind of mistake should be easier to spot than to make.

  This is the image from the Book 2, Section 14, Page 4 on the instructions from the Lego Website - [source](http://technic.lego.com/en-gb/buildinginstructions/8071_Group.aspx). Does yours look like this?
  
  To me it does look like it's not quite right - if you lift the yellow gear out, move the second part into position and then put the gear back it in it looks like it might fit, although the yellow gear wouldn't turn.
  
  I'd advise contacting Lego support, or see if you can pick out the way the person put it together in [this YouTube timelapse video](http://www.youtube.com/watch?v=Qa4VuL0SdEs&feature=player_detailpage#t=93s).
