[STAMP: RECEIVED] R.R.F.X. ========== There are two modifications which will have [struck through] to be definitely arranged for on all R.R.F.X. engines:- 1. The deflector for carrying oil from the camshaft covers to direct it on to the upper drive, is to be modified, and its position slightly altered, the baffle being made as a kind of horse-shoe piece as sketched on E.27921. herewith. 2. The second point is, we arranged a stronger camshaft bearing recently. The alteration went through, but it is necessary to instruct the Works that only this strengthened type must [underlined] be fitted to engines. BY.{R.W. Bailey - Chief Engineer} [Signature] By | ||
