| To DA.{Bernard Day - Chassis Design} from E.{Mr Elliott - Chief Engineer} -2- E3/G19/11/19 Contd. Referring to the gear meshing with the gear shaft, 16 diametral pitch should be used. The bush on the pinion shaft which projects back slightly into the gear box, should have a hole drilled in its projecting part to collect oil and form a means of lubrication.
