c. Apply a light coating of petroleum or multi-pur-
pose grease to inside of small end of cluster and
line inside of small end of cluster gear with nine-
teen needle rollers (13).
d. Stand carrier housing (16) on its side. Insert a
planet shaft (14), end with roll pin last, into one
of the planet shaft holes in carrier housing.
e. Note tab on thrust washer (15). Place thrust
washer onto end of planet shaft in carrier hous-
ing, placing tab of washer into slot in side of car-
rier housing.
f. Following the thrust washer, place assembled
cluster gear, large end toward roll pin holes,
onto planet shaft.
g. Following the cluster gear, place one more thrust
washer (15) onto planet shaft, placing tab of
thrust washer into slot in side of carrier housing.
Now insert planet shaft into opposite planet shaft
hole in carrier housing.
h. Using an alignment punch, align roll pin holes in
carrier housing and planet shaft, then drive roll
pin (18) into the aligned holes.
i. Repeat steps (a) through (h) to assemble and
install remaining two cluster gears.
3. Place hub assembly (9) on work surface with open
end facing up.
4. Oil all exposed surfaces inside hub, then lower inter-
nal gear (20), small end down, into hub.
BEWARE OF SHARP EDGES AND BURRS IN THE COUNTERBORE
WHEN INSTALLING O-RING.
5. Grease and place o-ring (23) into counterbore of
hub. O-ring can be made to fit counterbore exactly
by stretching it (if it is too small), or by squeezing it
together bit by bit as it is placed around the counter-
bore (if it is too large).
6. Place carrier assembly on work surface so one
planet shaft hole faces you and other two planet
shaft holes are opposite you. Line up punch marks
on gear teeth of carrier assembly to the 12 o’clock
position as shown in Figure 3-2. Place ring gear (21)
onto carrier to keep punch marks in position.
7. Lower carrier assembly into hub, meshing gears of
carrier with internal gear splines.
8. Place input gear (25) down into hub, into middle of
carrier.
9. Lift ring off of carrier carefully (so carrier gears do
not move) and replace ring gear (21) onto hub,
ensuring bolt holes in hub and ring gear are aligned.
BEWARE OF SHARP EDGES AND BURRS IN THE COUNTERBORE
WHEN INSTALLING O-RING.
10. Set cover (28) on work surface, interior side up.
Grease and place o-ring (23) into counterbore
around rim of cover. Make o-ring fit counterbore
exactly by stretching it or by pinching it together bit
by bit.
11. Grease and place thrust washer (27) halfway down
in counterbore in center of cover, until it rests on a
“ledge” in counterbore.
12. Grease and place thrust washer (22) around edge of
raised circular center of cover.
13. Lower cover, interior side down, onto ring gear. Align
bolt holes in cover and ring gear.
14. Grease and place thrust washer (29) into counter-
bore inside center of cover, on top of retaining ring
(30).
EYE PROTECTION SHOULD BE WORN DURING RETAINING RING
REMOVAL.
15. Place retaining ring into groove inside counterbore
in center of cover.
