Setting differential

Special tools, testers and aids required
♦ Wrench for ring nut MP 3-488
K - Use MP 3-488 to tighten bearing body to 150
Nm as far as the stop and secure.
- Tighten shim ring to 50 Nm and mark.
Note:
Do not rotate differential during the measu-
rement otherwise the bearings will settle and the
result of the measurement will be falsified.
- Turn on shim ring by five locking lugs and
secure; the preload of the taper roller bea-
rings is set in this way.
K Measuring friction torque
A - Commercially available torque gauge
0...600 Ncm
B - Wrench bit (width across flats 41 mm)
Replacing taper roller bearings for gea-
rboxes up to gearbox date of manufacture
26.4.1998
- Moisten these taper roller bearings with ATF
for inspecting the friction torque.
The friction torque of these taper roller bearings
must be 60...80 Ncm higher than the friction
torque which was measured previously at the
drive pinion.
Replacing taper roller bearings for gear-
boxes from gearbox date of manufacture
27.4.1998
K - Install these new taper roller bearings as
supplied, and do not oil additionally.
The friction torque of these new taper roller
bearings must be 35...100 Ncm higher than the
friction torque which was measured previously
at the drive pinion.
Note:
These new taper roller bearings have a modified
friction value. If these taper roller bearings are
oiled, it is not possible to achieve the stated
friction value.
