4. If previously removed, press bearing cups into hous-
ing. Cups should be pressed fully to shoulder of the
housing bore.
5. Fit inner bearing cone onto spindle. Make sure inner
bearing cone seats fully against spindle shoulder. If in-
ner bearing is not seated fully, lightly tap bearing cone
on inner hub until it seats properly.
6. Make sure that seal bore in housing is thoroughly
cleaned. If OD of seal is not rubber or does not have a
sealant coating, apply a light coating of silicone sealant
to seal bore in housing.
Install seal into housing so it is
flush with housing face.
7. Install boot seal. Cover surface of lip seal and boot
seal with grease.
8. Lightly oil bearing cups then place housing assembly
over spindle and inner bearing cone. Take care to not
damage seals or spindle during installation.
9. Fit outer bearing cone onto spindle.
10.Align key on spacer and install spacer onto spindle
shaft.
11. Align key on locking washer and install locking wash-
er onto spindle shaft.
IMPORTANT: .Perform the following steps without
interruption. Once the thread locking compound is
applied, you have only a few minutes before the cur-
ing process will influence the bearing lock nut
torque.
12.Install the bearing lock nut:
A. Apply high strength thread locking compound
(Loctite 263 or equivalent) and install the lock nut.
B. Tighten the lock nut to 110 ft − lb (150 N − m) .
C. Rotate the housing on the spindle a few revolu-
tions to align the bearings.
D. Tighten the lock nut to 150 ft − lb (200 N − m) .
E. Rotate the housing on the spindle a few revolu-
tions to seat the bearings.
IMPORTANT If installing the bearing nut with
the spindle installed on machine, have an assis-
tant hold the housing firmly in position during
the following step.
F. Loosen the lock nut completely, then tighten to 90
ft − lb (122 N − m).
IMPORTANT: Continue to tighten the lock nut
until it aligns with one of the locking washer tabs.
Do Not loosen the lock nut to align it with the
locking washer tabs.
G. Secure the lock nut by bending one of the locking
washer tabs into a slot in the lock nut.
13.Install secondary carrier and primary carrier making
sure that carrier gear teeth align with ring gear and
spline on spindle shaft.
14.If primary gear (item 25) was removed from drive
shaft, slide gear onto shaft and secure with retaining
rings.
15.Install drive shaft assembly (items 24 − 26) making
sure that drive shaft spline aligns with carrier gears.
16.Cover the outer face of the thrust plate with grease
and fit thrust plate onto end cap. Make sure that thrust
plate tabs are captive in end cap.
17.Apply a light coat of grease to a new O − ring and in-
stall it in the ring gear bore. Avoid pinching or cutting the
O − ring and install the end cap. Use a soft mallet to fully
seat the end cap.
18.Secure the end cap with the retaining ring. Make sure
the retaining ring is fully seated in the ring groove.
NOTE: If the planetary drive is not installed on the ma-
chine, check operation of planetary drive by hand. With
a constant turning force applied, rotation of the plane-
tary should be consistent. If there is more drag at certain
points, gears are not rolling freely and the planetary
should be examined for improper assembly or damaged
components.
19.Install wheel assembly.
20.Fill planetary drive with gear lube; refer to traction
unit Operator’s Manual. A portion of the gear lube will
pass into the brake assembly automatically.
21.Test planetary drive operation.
Failure to maintain proper wheel lug nut torque
could result in failure or loss of wheel and may
result in personal injury.
WARNING
22.Remove jack stands and lower machine to ground.
Tighten wheel lug nuts in a crossing pattern from 85 to
100 ft − lb (116 to 135 N − m) .
