| BY.{R.W. Bailey - Chief Engineer} from Hs{Lord Ernest Hives - Chair}/Rn.{Mr Robinson} 48005 Hs{Lord Ernest Hives - Chair}/Rn{Mr Robinson}5/LG18.9.28. RUBBER ENGINE MOUNTING. Experience has shewn that the bolts K.332 and F.78402 holding the top and bottom portions of the rubber engine foot together must be made a reamed fit in F.78142 and F.78141, otherwise the initial clearance rapidly increases due to vibration. This matter has already been taken up with the D.O. Hs{Lord Ernest Hives - Chair}/Rn.{Mr Robinson} | ||
