| (2) It will be seen that the inner sleeve with the teeth at each end must also be true on its outside dia. The alignment of the 1st. motion shaft will clearly have some effect on the functioning of the top gear cone, but can hardly affect the action of the 3rd speed cone. REDUCTION OF FRICTION. Although we do not think that the control stirrup has much to do with friction in the gear we should like to see a bronze stirrup tried. We should like it in bronze in order that the gear may work as freely as possible. DA{Bernard Day - Chassis Design}/HDY.{William Hardy} | ||
