Drive Pinion
Note: If you are using the same drive pinion, use the same
spacer that was originally in stalled in the assembly. If
the drive pinion is to be replaced, the original spacer will
be used as the starting point of adjustment.
7. Install the outer bearing cone.
8. Install a pinion nut finger tight. This will hold the pin-
ion in place while it is positioned into the press.
9. Align a 6” x 6” x 6” wood block under the drive pin-
ion, then lower the carrier and pinion assembly into
a press so that it is supported by the block.
10. Remove the pinion nut.
11. Place a press sleeve over the top of the outer bearing
cone. Use the press to apply 5 tons of force. It is
important to rotate the carrier slightly to make sure
that the rollers of the bearing are properly seated.
