FIGURE 41: Tighten screws to a torque of 140 N·m.
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 bearings with ring nut (26) on non-ring gear side in or-
der to increase the torque of the pinion.
In the case of used bearings, check thrust torque; in the
case of new bearings, check continuous torque.

CAUTION
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 dial indicator “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
