x202 To Mx.{John H Maddocks - Chief Proving Officer} Hs{Lord Ernest Hives - Chair}/Gry.{Shadwell Grylls}21/KW.3.9.35. Bentley Rear Axle: Even with the steel cage rear axle pinion bearing we are not entirely free from cage failures. We have reason to believe that the clogging effect of Whitmore's oil is conducive to insufficient lubrication at this point. As we have circulated a sheet for Hi-Press Oil, we recommend that all new axles are built with this from now on. Hs{Lord Ernest Hives - Chair}/Gry.{Shadwell Grylls} | ||
