| To RHC.{R. H. Coverley - Production Engineer} < 300 a (2) Hs{Lord Ernest Hives - Chair}/FJH.{Fred J. Hardy - Chief Dev. Engineer} 2/KW. 4.9.35. Servo on SpectreCodename for Phantom III II. In order to overcome the foul on the above servo when the brakes are worn and used in reverse, will you please fit the hollow rivet shown on N.Sch.4606, fig. 1, in place of the usual hardened pin with collar and split pin. The oil drip guard on the outer pressure plate should be cut back so that it does not foul the swinging arm before the servo reaches its stop. Hs{Lord Ernest Hives - Chair}/F.J.Hardy. | ||
