Da.{Bernard Day - Chassis Design} Rm{William Robotham - Chief Engineer}/Gry.{Shadwell Grylls}2/MH.{M. Huckerby}23.1.39. GEARBOX DIPSTICK. We agree with the idea of a one piece filler plug and dipstick. We think, however, felt should be avoided if possible. It is very messy when oily. We do not think, that with the stick placed where it is, any oil will leak past if the plug is metal with an adequate clearance. We believe Mx.{John H Maddocks - Chief Proving Officer} is trying both. Rm{William Robotham - Chief Engineer}/Gry.{Shadwell Grylls} | ||
