Hardy - Chief Dev. Engineer}15/JH.6.6.41. 30.G.VII. Rear Axle Failure. We attach a copy of H1/GLT's. report of the material condition of the pinion which failed in 30.G.VII's. rear axle. We believe that Ev{Ivan Evernden - coachwork}/Tln. has a suggestion for increasing tooth strength without altering the ratio by using coarser pitch gears.
