5. Apply a light coat of oil to the bearing cone rollers
and install the outer bearing cone onto
the spindle. Figure 4.27.
NOTE: The (3) M8 threaded holes in the wheel bear-
ing adjusting nut should be facing outward as the nut
is assembled against the wheel bearing cone. Rotate
the wheel hub by hand while tightening adjusting nut in
order to seat the wheel bearings and seal assembly.
6. Install the wheel bearing adjusting nut using the
wheel bearing adjusting nut tool 860901009T
per the special tools section, or equivalent. Tighten
the nut to 500 lb-ft (678 N•m).
7. Rotate the hub three to five revolutions in both
directions.
8. Tighten the nut to 500 lb-ft (678 N•m) again.
9.
Rotate the hub three to five revolutions in each
direction again.
10. Repeat above steps until nut torque level stabilizes.
11. Install the wheel bearing lock plate over the wheel
bearing adjusting nut and align the tabs on lock
plate with slots in the spindle.
12. Review the alignment of the holes in the lock
plate and holes in the spindle nut. Review amount
the spindle bearing nut must be loosened to make
the holes align with lock plate.
13. Repeat steps 11 & 12 with lock plate indexed 180
degrees and review the hole alignment in the lock
plate and wheel bearing adjusting nut.
14. Choose between the (2) lock plate positions that
requires the “least loosening” of the wheel
nut.The maximum recommendation is no more
than 5.5 degrees “loosening” of the adjusting nut.
NOTE: Do not further tighten the wheel nut to align
the capscrew holes.
15. Add a few drops of medium strength thread locker
to each capscrew threads to install the (3) lock
plate M8 capscrews and tighten per “Torque Table”
in section 6. Safely set the planetary wheel hub,
p
lanetary ring gear, and spindle assembly on
a workbench.
Planetary Spider Sub-Assembly
The planetary pinion shafts are not serviceable items
and should not have been disassembled from the
planetary spider.
Further sub-assembly of the planetary pinion gears,
needle rollers, and thrust washers is as follows if the
planetary spider gears had been removed.
Re-Use Components
If the re-assembly of the planetary spider will re-use the
components that were previously dis-assembled and
inspected:
1. Open each bag containing the previously removed
planet gear, snap ring, thrust washers, and needle
bearing components that were marked and match to
the planetary pinion shaft from which they were
removed. Keep these parts matched to their planetary
pinion shaft during assembly.
New Components
If new components are to be assembled on the
planetary pinion shafts, please follow the identical
recommended procedure:
Repeat the following steps for each planetary pinion
shaft /gear assembly.
1. Place the planetary spider with the (4) planetary
pinion shafts pointing upward in a safe workbench
orientation so the planetary spider assembly will not
roll or fall off the work bench and cause personal
injury or component damage.
2. Apply a light coating of oil or grease to the base of
planetary spider where the outer thrust washer will
be placed and the planetary pinion shaft,outer
thrust washer faces and slide the outer washer
over the pinion shaft and against the spider.
CAUTION
Nev
er mix new and old needle r
ollers, nor needle
rollers from different manufacturers, on the same
planetar
y pinion shaft and g
ear assemb
l
y
.
Component damage can occur.
T
wo optional methods of assembling the planetary
gears with needle rollers to each planetary pinion
shaft are recommended:
