| P 824. To Br.{T. E. Bellringer - Repair Manager} from Rm{William Robotham - Chief Engineer}/Std. c. Sg.{Arthur F. Sidgreaves - MD} Hd.{Mr Hayward/Mr Huddy} Rm{William Robotham - Chief Engineer}/Std.22/AP.16.7.37 We expect the higher speed drive 5 blade fans for Ph.III. to be ready by the early part of next week and have made arrangements for three sets to be supplied to N. The higher speed drive necessitates a modified starting handle bush support bracket - three sets of these will also be forwarded - this bracket is supported off the timing case studs and the present support bracket bosses and studs should be removed by filing flush with the timing case on the off-side i.e. the side corresponding to the slack side of the fan belt, otherwise the belt will foul these studs and bosses.
