1. Press inner bearing cone onto pinion.
2. Press inner and outer bearing cups into the carrier
until seated. Use a feeler gage (approximately
0.0015") to make sure bearing cups are fully seated
in bearing bores. Apply lubricant to both cup and
cone.
3. Place carrier housing in press with the pinion sup-
ported by wood block (6" X 6" X 6"), so the inner pin-
ion bearing is mated to the cone.
4. Insert original preload spacer and outer bearing onto
pinion.
5. Press outer bearing onto pinion until completely
seated.
6. Inspect end yoke or flange for grooves in seal sur-
face caused by contaminants. If grooves can be
detected with fingernail, then end yoke must be
repaired with a CR approved repair sleeve or
replaced.
7. Use yoke installer service tool and install yoke with-
out seal.
8. Use torque multiplier and torque pinion nut to
700-900 lbs. ft. (950-1,220 N•m).
9. Measure torque to rotate with an inch-pound torque
wrench. Torque measurements should be taken
every fourth revolution and should read between 10-
40 lbs. in. of bearing preload.
Note: If bearing preload does not fall within allowed limits,
preload can be increased by using a thinner spacer and
decreased by using a thicker spacer.
0.001" change in preload spacer thickness will change
torque to rotate approximately 30 lbs. in.
Note: Individual carriers may vary slightly.
