5. Tighten the nut on drive pinion to minimum 800 ft. lbs.
(1.085 Nm). maximum 1,100 ft. lbs. (1.492 Nm) (Figure 2-48).
6. Remove the yoke or flange bar.
Figure 2-48. Torquing Drive Pinion Nut.
7. Attach a torque wrench on the drive pinion nut Rotate the
drive pinion and read the value indicated on torque wrench
(Figure 2-49).
Figure 2-49. Reading Drive Pinion Torque.
NOTE: The preload (torque) of pinion bear-
ings can be increased or decreased by
tightening or loosening the pinion nut
within specifications.
8. If the preload (torque) of pinion bearings is not within
specifications. remove the pinion and cage assembly from car-
rier. Do the following procedure, then repeat steps 1 to 7. To
increase preload. install a thinner bearing spacer. To decrease
preload. install a thicker bearing spacer.
After adjusting preload of pinion bearings. remove the drive
pinion and bearing cage from carrier. Follow steps 1 to 4 of
•rocedure for removing pinion and cage from carrier.
If the carrier has a cover and seal assembly over the bearing
cage. install a new seal into cover as follows.
1. Apply Lubriplateor grease used for wheel bearings to the
seal lips and cavities between lips.
2. Apply a sealing compound on the outer diameter of seal.
3. Put the cover in a press, large diameter toward the top.
4. Support the cover under the small diameter opening with
metal or wood blocks (Figure 2-50).
PRESS
Figure 2-50. Pressing Seal Into Cover.
5. Press the seal into cover until seal is flat against the
bottom of bore. Use a sleeve or seal driver of the correct size
that fits against the metal retainer of seal (Figure 2-50).
NOTE: If a press is not available, use a
mallet and the sleeve or driver to install the
seal (Figure 2-51).
Figure 2-51. Installing Seal With Driver.
WARNING: Wear safe eye protection. Do
not hig steel parts or tools with a steel
hammer. Parts or tools can break and
cause injury.
If the pinion seal mounts directly into the bearing cage,
install a new triple-lip seal as follows.
1 Apply Lubriplate or grease used for wheel bearings to the
seal lips and cavities between lips (Figure 2-51).
2. Apply axle lubricant to seal bore in bearing cage (Figure
2-52).
