| X7460 BY.{R.W. Bailey - Chief Engineer} FROM E.{Mr Elliott - Chief Engineer} E2/MS.5.6.31. Copy to HS.{Lord Ernest Hives - Chair} PETROL PUMP - LeCs. 2897 & 2912. X.7460 X.5460 Referring to memos. BY6/G2631. and BY11/G2631., we think that the moving parts should be sufficiently lubricated in the designs as shewn because in the case of P. 2. there will very likely be a certain amount of direct oil spray flung off from the camshaft wheel and in the 20/25 scheme there is a large drilled hole communicating with the crankchamber through which oily vapour and spray will undoubtedly pass. Referring to the question of the hard fibre washer that is used on the A-C pump which is recognised by Derby as a good pump. The fibre washer is required for the purpose of making a petrol tight joint. With regard to your remarks in connection with deleting the steady on the cross control tube we made an experiment on the chassis down here under the personal direction of R.{Sir Henry Royce} to determine this point and we found that the cross tube without the support was extremely rigid, far more in fact than was necessary for the load it had to carry.
