Forward Assembly
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
from 5–13 lbs. This specification is translated into
lbs. in. readings 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.
Use the correctly sized spacer. Do not use shim stock or
grind spacers. These practices can lead to loss of bearing
preload and gear or bearing failure.
8. Press pilot bearing on pinion.
To prevent bearing damage, use suitable sleeve that only
contacts the inner race of bearing cone.
9. Stake pilot bearing using staking tool. This is essen-
tial to retain the bearing.
