| B. (crossed out) FROM DA.{Bernard Day - Chassis Design} C. to HS.{Lord Ernest Hives - Chair} (crossed out) LUBRICATION OF REVERSE. ALL SYNCHRO MESH GEARBOXES. DA{Bernard Day - Chassis Design}1/W2.22.12.31. X5310. Y7310. Herewith we send N. sch 3305. shewing a further development of the method of lubricating the reverse shaft on the above gearboxes, which is to supersede those already sent you. It should be applied to all the gearboxes but if you have a shaft already made, say for the 25H.P., we do not think it is necessary to delay the test in order to effect this alteration. D.A. | ||
