12. With 15 tons of force on the press, you should be
able to feel a small amount of drag from the bearing
as you rotate the carrier. If the carrier turns with no
drag at all, the pinion spacer thickness should be
decreased by using a thinner spacer. If the carrier is
hard to turn, the spacer thickness must be
increased.
13. Remove the carrier from the press. Secure the car-
rier in a head stand.
Note: Do Not Install the Pinion Seal at this time.
14. Install the drive yoke and pinion nut.
15. Torque the nut to 800-1000 lb-ft.
(1084-1355 N•m).
16. Use an lb-in torque wrench and correct socket to
check the rolling torque of the pinion. Read torque
while rotating the assembly. Record the rotating
torque, not the breakaway torque. Torque must be
between 20 to 50 lb-in. If the torque recorded is not
within the specified torque, the pinion spacer must
be changed. Repeat Steps 6-17.
17. Now remove the pinion nut and yoke and install the
pinion seal. Use Spicer’s seal drive (part number
210749) and drive adapter (part number 131472).
18. Reinstall the yoke and pinion nut. Torque to 800-
1000 lb-ft.
