Drive Pinion
12. With 5 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.
14. Install the drive yoke and pinion nut.
15. Torque the nut to 800-1000 lbs. ft.
(1084-1355 N•m).
16. Use an in. lbs. 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 lbs. in. If the torque recorded is not
within the specified torque, the pinion spacer must
be changed. Repeat Steps 6-17.
