CRANKSHAFT & CRANKCASE. LeC. 2953. We send you herewith a blueprint of the above giving particulars which will enable you to order the forgings for the crankshaft, and shewing some modifications it is required to make to the shape of the crankcase. These latter have been occasioned mainly by the introduction of the starter motor mounting and drive as shewn on the drawing. Regarding the front end of the crankshaft we would refer you to the print we sent of LeC. 2947., but some extra length should be left on over and above that given on LeC. 2947.
