FIGURE 42: Only if ring nuts have been removed, tighten the
ring nut (2) on ring gear side until clearances between pinion
and ring gear are zeroed. Then, loosen by about 1/4 turn.
FIGURE 43: Only if ring nuts have been removed, preload be-
arings with ring nut (26) on non-ring gear side in order to in-
crease the torque of the pinion.
In the case of used bearings, check thrust torque; in the
case of new bearings, check continuous torque.
FIGURE 44: Apply torque meter TM to pinion nut and check
that torque will increase by 20 - 40 N·cm as a result of diffe-
rential bearing preload.
Example: pinion torque: 120 - 130 N·cm differential
torque: 140 - 170 N·cm.

FIGURE 45: Introduce a gauge “A” with long tracer through
the hole provided for the cap. Position the tracer on the side of
a tooth of the ring gear, approximately 5 mm from the outer
rim; preload by about 1 mm and zero the gauge.
FIGURE 46: As you hold the pinion in position, move the ring
gear manually in both directions to check clearance between
pinion and ring gear. Standard clearance: 0,25 - 0,33 mm
FIGURE 47: If torque and/or pinion-ring gear clearance is not
within tolerance values and the ring nuts have not been remo-
ved, mark the position of the ring nuts (2, 26) and remove the
safety plates (1, 27).
