LEC.5433 Crankshaft with increased diameter journal bearings. We are now receiving details for bearings, both main and connecting-rod, in connection with the above. We send you herewith drawings; we would like your confirmation as regards the materials to produce these, as we have our doubts as to the latest specification you require. We should also like you to consider the question of either converting engines or producing new engines with this large diameter crankshaft, as it means the production of new crankcases.
