Herewith is PD.103 Gearbox Actuating Mechanism. The actuation is shewn for both ordinary ratios and overdrive. The boss for the gearbox mounting is being fixed up elsewhere and is not shewn in what will probably be the final position. The spherical joint for the change gear shaft may require further protection against oil leakage, but it is intended to try it first as drawn. Details can be made directly from this drawing.
