Risk of injury due to falling parts.
Slight or moderate injury possible.
ð
Secure parts against falling down.
Also, secure the portal housing with a crane.
30. Rotate input flange several times into both directions.
31. Check total rolling torque.
Total rolling torque at axle ratio i < 7.38
Total rolling torque = Pinion bearing rolling 2 Nm (±1 Nm)
Total rolling torque at axle ratio i > 7.38
Total rolling torque = Pinion bearing rolling 1.5 Nm (±0.5 Nm)
If the required rolling torque is not achieved, replace the disk as specified below:
▪ In case of an insufficient rolling torque, install a thicker shim.
▪ In case of an excessive rolling torque, install a thinner shim.
32. Remove portal housing.
33. Use AA01.266.870 [Load-lifting equipment] to remove the differential from the axle housing.
