WRAITH WATER PUMP THRUST PADS & BUSHES Further to Rm{William Robotham - Chief Engineer}/Std.6/MW.12.1.39., we have carried out machining tests with samples of actual Ferodo material to confirm the machining figures supplied for pieces EW.1996/7 viz. 4½d and 3½d respectively and do not anticipate these figures will be exceeded on a production basis. We therefore recommend that the material be bought as rod from Messrs. Ferodo and the pieces EW.1996/7 machined at R.R. RHC{R. H. Coverley - Production Engineer}/G.T.Houliston. Geo.T.Houliston | ||
