328. E.{Mr Elliott - Chief Engineer} from Rm{William Robotham - Chief Engineer}/Gry.{Shadwell Grylls} Da.{Bernard Day - Chassis Design} By.{R.W. Bailey - Chief Engineer} Hdy.{William Hardy} Rm{William Robotham - Chief Engineer}/Gry{Shadwell Grylls}6/R.11.3.37. P.III GEARBOX. We have now dynamometer tested with Cadillac gears the side shaft strengthened rear end, N.Sch. 4969, the retaining nut having a right-hand thread. Ten hours full throttle in 2nd gear were completed without any failure. Other features of the test were that the rear bearing of the 3rd motion shaft was a Schatz bearing and the flanges of the 2nd speed pinion bushes were separate from the bushes. The Schatz bearing was in perfect condition after the test (no light running had been done). The gears had previously completed 11,000 miles in 37-EX and were not cracked.
