RE STARTER FOR AMERICAN CHASSIS. ----------------------------- On drawing LeC.1155 it is specified in error that the tooth portion of the flywheel should be made of C.H.N.S. Would you kindly note that material for this part should be 3% carbon steel heat treated before the gear cutting operation. Incidentally, I might mention that in the scheme of the final information required for the American chassis engine starter, we shall shew the teeth on the flywheel narrower than given on scheme LeC.1155.
