F. Lightly oil bearing journals on spindle shaft. Slide<br />
housing onto spindle (item 1) taking care to not damage<br />
seal or spindle. Make sure that bearing in housing<br />
fully seats against spindle shaft shoulder.<br />
G. Install outer bearing cone (item 8) onto spindle.<br />
NOTE: The planetary shim kit includes the retaining<br />
ring and several thrust washers with thickness in incremental<br />
steps of 0.004 in. (0.10 mm).<br />
H. Measure thickness of thrust washer (item 9) that<br />
was removed during disassembly. Choose new<br />
thrust washer of equal thickness or the next available<br />
thickness from thrust washers in the shim kit.<br />
I. Apply a light coating of oil to spindle shaft, thrust<br />
washer and retaining ring. Install thrust washer onto<br />
spindle shaft.<br />
WARNING<br />
If retaining ring (item 10) is not fully installed in<br />
spindle groove, loss of wheel and personal injury<br />
may result.<br />
J. Carefully install new retaining ring (item 10) into<br />
the spindle shaft groove taking care to not distort<br />
ring. If the proper thrust washer has been installed,<br />
the retaining ring should fit tightly between the thrust<br />
washer and spindle groove. Tap the OD of the retaining<br />
ring starting in the center and working out toward<br />
each end to ensure that the retaining ring is<br />
properly seated into the spindle groove. After correct<br />
assembly, make sure that retaining ring ID is fully<br />
seated to spindle shaft groove.<br />
K. After retaining ring is installed, make sure that<br />
there is no endplay in assembly. If required, remove<br />
retaining ring and install a thrust washer of different<br />
thickness to adjust endplay.<br />
3. Install carrier assembly (item 18) making sure that<br />
carrier gear teeth align with ring gear and spline on<br />
spindle shaft.<br />
4. Install drive shaft (item 17) making sure that drive<br />
shaft spline aligns with carrier gears.<br />
5. Install thrust plug (item 15) and thrust washer (item<br />
16) into end cap (item 14). Make sure that thrust plug<br />
and thrust washer are captive on inside of end cap.<br />
6. Install new O--ring (item 21) to end cap (item 14) and<br />
then install end cap. Secure cap with retaining ring (item<br />
12).<br />
7. Check operation of planetary wheel drive. With a<br />
constant turning force applied, rotation of the planetary<br />
should be consistent. If there is more drag at certain<br />
points, gears are not rolling freely and the planetary<br />
should be examined for improper assembly or damaged<br />
components.<br />
8. If planetary wheel drive assembly is installed on machine:<br />
A. Install wheel assembly.<br />
WARNING<br />
Failure to maintain proper wheel lug nut torque<br />
could result in failure or loss of wheel and may<br />
result in personal injury.<br />
B. Lower machine from jack stands. Torque lug nuts<br />
from 85 to 100 ft -lb (115 to 135 N -m).<br />
C. Make sure drain plug is installed in bottom of<br />
brake assembly. Fill planetary wheel drive/brake assembly<br />
with SAE 85W--140 gear lube. Capacity is<br />
approximately 16 fl. oz. (0.47 liters) per wheel.<br />
L. Install new O--ring (item 21) to housing.<br />
Axles, Planetaries and Brakes<br />
