Main Assembly
1. Position hub on its output shaft so that hubs small
diameter end points down.
2. Using a marker, mark the four shoulder bolt holes
in hub.
3. Grease O-ring and place in counterbore in hub.
NOTE: O-rings may be stretched or squeezed
together in order to fit exactly in counter-
bore.
4. Oil all exposed surfaces inside hub. Oil carrier
sub-assembly.
5. Place carrier sub-assembly, with spline connec-
tions down, into mesh with output shaft.
6. Place ring gear, with squared shoulder down, into
mesh with the planet gears of the carrier sub-
assembly. Make sure that marked shoulder bolt
hole on ring gear aligns with any of the marked
shoulder bolt holes on the hub. "X" mark should
be on the cover side of ring gear.
7. Start one half of retaining ring into groove inside
input gear. Use a soft punch to press the remain-
ing half of the retaining ring into the groove.
8. Insert input gear, with large diameter end down,
into mesh with planet gears.
9. Place large thrust washer over input gear so it
rests on carrier housing. Oil all exposed surfaces
inside hub.
10. Grease O-ring and place into counterbore of
cover.
NOTE: O-rings may be stretched or squeezed
together in order to fit exactly in counter-
bore.
11. Place cover on top of ring gear so the fill hole will
be at top of hub when it is installed.
12. Install four shoulder bolts into shoulder bolt holes
and tighten.
13. Install eight cap screws in remaining holes and
tighten.
14. Apply 23-27 ft. lbs. (31 - 37 N-m) of torque to all
bolts.
15. Apply a light coat of "Never Seize" to both pipe
plugs and install into the two holes in cover.
16. Roll test the unit in both clockwise and counter-
clockwise directions. Turn hub nine full revolu-
tions in each direction.
17. Leak test the hub at 5 PSI (7 N-m) for two to three
minutes.
