The pdf drawings that I downloaded
here have a lot of dimensions listed, but they do not appear to show the distance from the output sprockets, to the housing. how far over are the sprockets, so we know exactly where to run the chains? Adding two more dimensions to the lower left drawing of sheet 2 would be helpful.
(I am not using inventor yet to model the design, still in the sketching stage, so the pdf drawings are the only source of info available right now)
