| (2) (3) The outer races of the two roller bearings are secured by riveted pins and washers. (4) Adjustment is provided on the sliders for 1st. and 2nd. and reverse, but none for top and 3rd. (5) The biting in bolts on the forks locate the sliders rotationally, and in the case of reverse it is necessary that the location be accurate as the height of the plate for reverse stop is of some importance. (6)' The slots for plunger balls in sliders are milled right across instead of being spherical depressions. This calls for less accuracy in rotational location of the sliders. (7) The reverse slider can be built up with a piece pressed on for the pendulum lever, or can be solid as preferred. (8) We believe that the wide reverse pinion presents difficulty with grinding. R.{Sir Henry Royce} has said that if this is so we should profile grind, or send out the gear for grinding, or do without grinding rather than divide the pinion into two. HDY.{William Hardy} | ||
