NOTE:
Make sure the duo-cone seal components are not
pinched or displaced when the housing is
installed.
13.
Install housing (8) over spindle (32) with the largest
inside diameter facing downward.
14.
Install bearing cone (39) on spindle (32).
15.
Install bearing nut (38) on spindle (32). Use Tool (A) to
tighten the bearing nut to a minimum torque of 825 N·m
(600 lb-ft). Make sure that the bearing nut is at or past
the reference line marked in step 8.
16.
Using a hammer and punch, stake bearing nut (38) in
one place.
17.
Install external retaining ring (33) in the groove on the
outside of coupling (37). Install internal retaining ring
(35) in the groove located near the middle of the inside
of the coupling.
18.
Apply a light coating of clean grease on thrust spacer
(36). Install thrust spacer (36) on spindle (32).
NOTE:
Gears (30) are a matched set. If one of the gears
needs replacing, all must be replaced. If the gear
or roller bearing needs to be replaced, both must
be replaced, as the assembly of the components
is permanent. Each new roller bearing has a
retainer around it for easier installation into the
gear.
19.
Apply a light coating of clean oil on five gears (30) and
roller bearings (31).
20.
Center roller bearing (31) and the retainer on the end of
gear (30) with the large chamfer on its inside diameter
and push the roller bearing through the retainer into the
gear until it snaps into the groove of the gear.
21.
Install each of the five roller bearings and gears (30) on
spindle (32).
22.
Install five retaining rings (29) on the spindle to hold
each of the roller bearings and gears in place.
23.
Use the following procedure to assemble second stage
carrier (10).
a.
Install sun gear (22) in carrier (25), and install
retaining ring (24).
b.
Apply a light coating of clean oil on planet gear (20)
and roller bearing assembly (21).
NOTE:
Roller bearing assembly (21) consists of two
internal retaining rings, needle bearings and an
inner race carrier. A new roller bearing assembly
comes packaged with a retainer to keep the
needle bearings in place for easier installation.
c.
Install one of the internal retaining rings from the roller
bearing assembly into planet gear (20).
d.
Use the retainer to install roller bearing assembly (21)
in planet gear (20). The retainer should slide off
during assembly.
e.
Install the other internal retaining ring from the roller
bearing assembly into planet gear (20).
f.
Install the roller bearing assembly and planet gear
(20) on carrier (25). Install retaining ring (23) to hold
the planet gear in place.
g.
Repeat steps (c) through (f) for the two remaining
planet gears.
