Adjust opposing nut to obtain correct crown
wheel backlash.
44. Rotate pinion in both directions to settle
bearings.
45. Measure in 3 places to obtain correct crown
wheel backlash.
NOTE: Crown wheel backlash should be within
0.076 mm - 0.177 mm (0.003' - 0.007').
46. Align adjusting nuts to next roll pin slot, do not
