| X5310 BY.{R.W. Bailey - Chief Engineer} FROM DA.{Bernard Day - Chassis Design} C. to SG.{Arthur F. Sidgreaves - MD} HS.{Lord Ernest Hives - Chair} REVISED EPICYCLIC 3rd. SPEED GEARBOX. DA{Bernard Day - Chassis Design}1/M16.10.30. X. 523. X.5310. X.7310. We send herewith N. schemes N.50/51.. showing particulars of the casing of this gearbox. The gearbox is joined on to the cone of the present clutch casing which for the moment is otherwise unaltered, but it may be necessary to extend the front brake differentials to line up with the balance lever on the servo. We also send N. sch. 3156. shewing the actuating gear for the three speed box. DA.{Bernard Day - Chassis Design} | ||
