The position with the greatest smoothness of operation is determined by shifting the pinion shaft in axial direction. This position is then marked on the crown wheel as the installationdimension "E", 383_99 E = Installationdimension 1 = Installationdimension "E" (e.g. 70.27 mm) 2 = Circumferentialbacklash "F" (e.g. 0.14 mm) 3 = Pairing number 39 08 15 Adjusting drive set -GT3 39 -219 Printed in Germany -29, 1999 GT339219
