HS{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer} E/HDY.{William Hardy}3/HP.28.1.36. SpectreCodename for Phantom III Back Axle. We understand from RHC{R. H. Coverley - Production Engineer}/RH{R. Hollingworth} that excessive deflection is taking place in the pinion mounting which reveals itself by taking up the clearance in the oil retaining screw thread unless this is made more than the normal amount. We should be glad if confirmation could be obtained by a static test with, if possible, information as to which pieces are primarily responsible. E/HDY.{William Hardy} | ||
