Pinion Assembly
4. Press outer bearing cone on pinion.
To prevent bearing damage, spin cage while pressing outer
bearing on.
5. Apply clamp load to the pinion bearing cage assem-
bly. Either install the yoke (or helical gear) and
torque the pinion nut to specifications or use the
press to simulate nut torque (see chart below).
*Torque nut to 840 ft.lbs. (1,140 N•m), then continue
tightening nut to align nut slot to nearest hole in pinion
shank.
Note: *Specifications for finial Pinion Bearing Preload Test.
Torque to rotate bearing cage 15 -35 in.lbs. (1.7 - 4.0
N•m)
Vise Method
a. If the yoke and nut are used, mount the assembly in
a vise, clamping yoke firmly.
Press Method
a. If a press is used, position a sleeve or spacer so that
load is applied directly to the back face of the outer
bearing cone.

6. Measure Pinion Bearing Preload: Use a spring scale
to test the assembly rolling torque. To use the spring
scale, wrap flexible wire around the bearing cage,
attach the scale and pull. Preload is correct when
torque required to rotate the pinion bearing cage is
within the specifications Listed in the previous chart.
Read only the torque value after the bearing cage starts to
rotate.
7. Adjust Pinion Bearing Preload: If necessary, adjust
pinion bearing preload. Disassemble the pinion bear-
ing cage as recommended in this manual and
change the pinion bearing spacer. A thicker spacer
will decrease preload. A thinner spacer will increase
preload.
