GENERAL
The dimensions for adjusting the distance between the face of the pinion and the center of the crown wheel are stamped into the end face of the pinion (see example below).

NOTE: Always measure the positions of the pinion and crown wheel before dismantling the gearbox. This is to check whether their locations are correct. If the pinion and crown wheel assembly has been in service for a relatively short distance (less than 10000 km) re-adjustment may be carried out. But if it has been in service for a longer distance and the gears have become worn-in, their settings during re-assembly should be the same as those measured before dismantling.





End Face Of Pinion
+3 = Dimension for setting the pinion
R913 = Matching number, also stamped on the crown wheel
0 = Pinion not offset - its centerline intersects the crown wheel centerline. All pinions are stamped 0, and this figure is not relevant to the adjustment.
