| To RHC.{R. H. Coverley - Production Engineer} X328 Hs{Lord Ernest Hives - Chair}/PJH.11/KW.18.9.35. When you dismantle the gearbox of SpectreCodename for Phantom III III, will you please measure the load required to move the top and 3rd S.M. sleeve against the resistance of the plungers. It is important that this should be done before the sleeve itself is removed from the shaft, so that the present conditions are not disturbed. Please carry out the same measurements on the 2nd speed S.M. sleeve. Hs{Lord Ernest Hives - Chair}/F.J.Hardy. | ||
