RE CRANKSHAFTS FOR 250 EAGLE ENGINES. --------------------------------- With reference to By8/P11919, the tests carried out in the Experimental Dept. have been with American Crankshafts, with the three central journals strengthened. And these tests have not shown up any weakness. We think that American Crank-shafts, providing they have the strengthened journals, can be used. The fact that none of the American Crankshafts have been fitted with the reduced oil plug on the top of the web, or had the metal at this point increased, is not, we think, suffic-ient reason to scrap these shafts.
