| X214 To EY. from E/JNR.{Charles L. Jenner} c. Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer} RHC{R. H. Coverley - Production Engineer} E/JNR.{Charles L. Jenner}2/HP.3.1.35. re Bentley Connecting Rod Bolts. Referring to Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer}2/MJ.1.1.35, we have made a drawing which we send you herewith - LeC.4281 showing the big-end bolts increased in diameter. We think the existing forgings can be used as we have not altered the bolt centres. New nuts of course will be required. The clearance in the crankcase will be unaltered. LeC.4281 herewith.
