F. Lightly oil bearing journals on spindle shaft. Slide
housing onto spindle (item 1) taking care to not damage
seal or spindle. Make sure that bearing in housing
fully seats against spindle shaft shoulder.
G. Install outer bearing cone (item 8) onto spindle.
NOTE: The planetary shim kit includes the retaining
ring and several thrust washers with thickness in incremental
steps of 0.004 in. (0.10 mm).
H. Measure thickness of thrust washer (item 9) 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 and retaining ring. Install thrust washer onto
spindle shaft.
WARNING
If retaining ring (item 10) is not fully installed in
spindle groove, loss of wheel and personal injury
may result.
J. Carefully install new retaining ring (item 10) 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 retaining
ring starting in the center and working out toward
each end to ensure that the retaining ring is
properly seated into the spindle groove. After correct
assembly, 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.
3. Install carrier assembly (item 18) making sure that
carrier gear teeth align with ring gear and spline on
spindle shaft.
4. Install drive shaft (item 17) making sure that drive
shaft spline aligns with carrier gears.
5. Install thrust plug (item 15) and thrust washer (item
16) into end cap (item 14). Make sure that thrust plug
and thrust washer are captive on inside of end cap.
6. Install new O--ring (item 21) to end cap (item 14) and
then install end cap. Secure cap with retaining ring (item
12).
7. Check operation of planetary wheel drive. With a
constant turning force applied, rotation of the planetary
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.
8. If planetary wheel drive assembly is installed on machine:
A. Install wheel assembly.
WARNING
Failure to maintain proper wheel lug nut torque
could result in failure or loss of wheel and may
result in personal injury.
B. Lower machine from jack stands. Torque lug nuts
from 85 to 100 ft -lb (115 to 135 N -m).
C. Make sure drain plug is installed in bottom of
brake assembly. Fill planetary wheel drive/brake assembly
with SAE 85W--140 gear lube. Capacity is
approximately 16 fl. oz. (0.47 liters) per wheel.
L. Install new O--ring (item 21) to housing.
