I am busy attempting to assemble Technic 8071, and have encountered a problem.
On page 83 of the first manual, a yellow gear (4203493) together with a grey splined rod (4211815) is added to the sub-assembly in diagram 13.
A little later, in book 2 page 4, diagram 14, two sub-assemblies are being joined, but the yellow gear is in the way. If you remove the yellow gear, everything goes together just fine.
I have backtracked through the instructions and re-assembled everything carefully, but there remains the possibility that I have made a mistake. Right now, it looks to me as though the documentation is incorrect. Can anyone confirm either that they have encountered the same problem, or that on the contrary, they have assembled the kit successfully? Is it just that I'm looking the wrong way at the diagram?
