C. Make sure that seal bore in housing is thoroughly
cleaned. If OD of seal (item 3) is not rubber or does
not have a sealant coating, apply light coating of sili-
cone sealant to seal bore in housing. Install seal into
housing so it is flush with housing face. Lightly
grease seal lips.
D. Pack boot seal (item 2) with grease and install.
E. If ring gear was removed from housing, place
dowel pins (item 10) in housing. Secure ring gear to
housing with lock washers (item 8) and socket head
screws (item 7). Torque socket head screws from
118 to 144 in − lb (13.3 to 16.3 N − m) .
F. Lightly oil bearing journals on spindle shaft. Slide
housing assembly onto spindle (item 1) taking care
to not damage seal or spindle. Make sure that inner
bearing fully seats against spindle shaft shoulder.
G. Install outer bearing cone (item 12) onto spindle.
NOTE: The planetary shim kit includes the retaining
ring and several thrust washers with thickness in in-
cremental steps of 0.004 inch (0.10 mm).
H. Measure thickness of thrust washer (item 14) that
was removed during disassembly. Choose new
thrust washer of equal thickness or the next available
thickness from thrust washers in the shim kit.
I. Apply a light coating of oil to spindle shaft, thrust
washer (item 14) and new retaining ring (item 15).
Install thrust washer onto spindle shaft.
WARNING
If retaining ring (item 15) is not fully installed in
spindle groove, loss of wheel and personal inju-
ry may result.
J. Carefully install new retaining ring (item 15) into
the spindle shaft groove taking care to not distort
ring. If the proper thrust washer has been installed,
the retaining ring should fit tightly between the thrust
washer and spindle groove. Tap the OD of the re-
taining ring starting in the center and working out to-
ward each end to ensure that the retaining ring is
properly seated. Make sure that retaining ring ID is
fully seated to spindle shaft groove.
K. After retaining ring is installed, make sure that
there is no endplay in assembly. If required, remove
retaining ring and install a thrust washer of different
thickness to adjust endplay.
L. Install new O − ring (item 13) into groove in hous-
ing.
4. Install secondary carrier (item 28), secondary gear
(item 27) and primary carrier (item 26) making sure that
carrier gear teeth align with ring gear and spline on
spindle shaft.
5. If primary gear (item 24) was removed from drive
shaft, slide gear onto shaft and secure with retaining ring
(item 23).
6. Install drive shaft assembly (items 25, 24 and 23)
making sure that drive shaft spline aligns with carrier
gears.
7. Install thrust plug (item 21) and thrust washer
(item 22) into end cap (item 20). Make sure that thrust
plug and thrust washer are captive on inside of end cap
(item 20).
8. Install new O − ring (item 13) to end cap and then
install end cap. Secure cap with retaining ring (item 17).
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.
9. Install wheel assembly.
10.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.
11. 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
12.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) .
