Output Carrier Assembly
(Refer to Figure 3-4., Output Carrier)
1. Place Thrust Washer (4H) into counterbore of Carrier
(4A). BE SURE the small diameter side of Washer
(4H) facing planet gear side.
2. Place Planet Gear Sub-assembly (4) into Carrier
(4A). Visually align the planet gear bore with one of
the planet shaft holes on the Carrier (4A).
3. Insert a Planet Shaft (4E) into the planet shaft hole
described in Step 2 on Carrier (4A). The end of the
planet shaft that does NOT have the roll pin hole
should be inserted into the Carrier (4A) FIRST.
4. Now insert Planet Shaft (4E) through the first set of
Thrust Washers (4B), Planet gear, then the second
set of Thrust Washers (4B). Use an alignment punch
or similar tool to align roll pin holes on Carrier (4A)
and Planet Shaft (4E).
NOTE: Be sure not to hit the Planet Gears (4F) when driving
in Roll Pins (4G).
5. Drive Roll Pin (4G) down into the aligned roll pin
holes. Pin should be flush with OD of Carrier (4A).
6. Repeat Steps 1-5 for the installation of the two
remaining Planet Gears (4F).
Hub-Spindle Assembly
(Refer to Figure 3-7., Hub Spindle)
NOTE: Spray a light film of oil on all component parts during
assembly.
1. Place Hub (1G) into pressing base. Press nine Studs
(1H) into Hub.
NOTE: Use enough pressure to press in studs. Don’t use
excessively high pressure to press in studs or hub
may crack.
NOTE: Spray a generous amount of oil on bearings during
installation.
2. Press Bearing Cup (1D), position "A", into Hub (1G)
using appropriate pressing tool.
3. Turn hub over and press Bearing Cup (1D), position
"B", into hub using appropriate pressing tool.
4. Place Bearing Cone (1E), into Bearing Cup (1D),
position "B".
5. Grease Seal (1B) lip and press seal into Hub (1G)
using appropriate tool until seal is flush with end of
hub.
6. Press Seal Boot (1Q) onto Hub (1G) if required. Turn
Hub (1G) over and lower onto Spindle (1A).
7. Install Bearing Cone (1C) into Bearing Cup (1D),
position "A".
8. Place Bearing Spacer (1N) on top of Bearing Cone
(1C).
9. Using appropriate tool, install Retaining Ring (1J)
into Spindle (1A) groove. Make sure ring is com-
pletely seated in groove.
NOTE: Extra bearing pre-load caused by using tool in Step
#9 must be removed. This should be done by plac-
ing a tool (NOT THE SAME TOOL USED IN STEP #9)
on the end of the spindle, and then striking the tool
with a piece of barstock. This should be adequate to
remove any additional bearing pre-load.
