Only if the differential clearance and preload adjustment ring nuts
have been removed, tighten the ring nuts (1) by 3 turns approx.;
coat with Loctite 222 and tighten in the relative intermediate
covers.
Tighten the ring nut (1) on gear ring side until clearances between
pinion and gear ring are zeroed. Then, loosen by about 1/4 ± 1/2
turn.
Only if ring nuts have been removed
. Preload bearings with ring
nut (1) on non-gear ring side in order to increase the torque of the
pinion.
ATTENTION!
In the case of used bearings, check thrust torque; in
the case of new bearings, check continuous torque.
Apply torque meter TM to pinion nut and check that torque will
increase by 20-40 Ncm as a result of differential bearing preload.
Example: pinion torque: 120-130 Ncm
differential torque: 140-170 Ncm.
Introduce a comparator "
A
" with long tracer through the hole
provided for the cap (12).
Position the tracer on the side of a tooth of the gear ring,
approximately 5 mm from the outer rim; preload by about 1 mm and
zero the comparator.
As you hold the pinion in position, move the gear ring (14) manually
in both directions to check clearance between pinion and gear ring.
Standard clearance. See table
CAUTION!
Difference between MIN. and MAX. clearance for whole
circumference must not exceed 0.09 mm.
