Disassemble Planetary Wheel Drive
that can be assembled into the ring grooves of the
spindle shaft above the bearing cone. Bearing should
have from 0.000 to 0.006 inches (0.00 to 0.15mm) of
end play when the proper retaining ring is installed.

Remove primary sun gear (13) and thrust washer
from the end of the input shaft. Remove primary
carrier assembly (15).

Apply a bead of RTV compound or equivalent to the
hub face that mates with ring gear (24). Assemble end
of the ring gear having 6 or 12 bolt holes against the hub
with the bolt holes of the hub and ring gear aligned. As-
semble six 3/8−24x1−7/8 inch hex head bolts. Torque
bolts from 39 to 49 ft−lb (5.4 to 6.8 kg−m). If grade 8 bolts
are used, torque bolts from 52 to 60 ft−lb (7.2 to 8.3
kg−m). Grade 8 bolts can be identified by the 6 radial
lines on bolt head.

is encountered in removing the carrier.
Remove secondary carrier assembly (20). It may be

Remove ring gear (24). It may be necessary to strike ring
gear with a rubber mallet to loosen from hub.
Remove 6 or 12 bolts from the hub and ring gear.
9.
Assemble primary carrier and sun gear into the ring
gear. It is necessary to rotate the carrier and pinion to
align the sun gear teeth with the secondary pinion and
primary pinions with ring gear teeth. Assemble primary
sun gear (13) over the input shaft. Rotate sun gear to
align the shaft to gear splines and gear teeth.
NOTE: Use snap ring expander tool to remove the re-
taining ring.

shaft and against the shoulder of shaft.
Assemble small thrust washer (12) over the input
the tapered bearing. Lift hub (8) from the spindle. If
bearings are not a loose fit, it may be necessary to
press spindle from the hub.
11.
Assemble O−ring (21) in the groove of the disen-
gage plunger (22). Assemble plunger over the end of in-
put shaft and against the thrust washer.

from the hub. Inspect bearing cups (6) in position and re-
move only if replacement is required.
Remove oil seal (4) and bearing cones (5 and 9)
12.
Lubricate O−ring in the groove of the engage plung-
er. Assemble thrust washer (23) with tangs engaged
with the large cover (19). Apply a bead of RTV com-
pound or equivalent to the end face of the ring gear. As-
semble cover over the plunger as holes of cover and ring
gear are aligned. Assemble eight 5/16−18x1 inch hex
head bolts. Torque bolts from 20 to 25 ft−lb (2.8 to 3.5
kg−m).
Assembly of the Planetary Wheel Drive
1.
Press a new bearing cup (6) into each side of the
hub (8).
2.
Assemble bearing cone (5) into the cup (6) at the
seal end of the hub. Press a new oil seal (4) into the hub.
3.
Position spindle (3) upright on bench. Lubricate lips
13. If the wheel is to be used to drive the vehicle, as-
semble disengage cover (18) with the dimpled center
protruding out. Assemble and torque two 5/16−18x3/4
inch bolts. Torque bolts from 10 to 20 (1.4 to 2.8 kg−m).
of oil seal (4) and lower hub onto the spindle. Hub (8)
should be centered as it is lowered over the spindle to
prevent seal damage.

the bearing cup (6). Select thickest retaining ring (28)
Assemble bearing cone (9) over the spindle and into
14. Invert Power Wheel assembly. Assemble coupling
(1) with the counterbore out to the input shaft.
