Output Carrier Assembly
NOTE: Refer to Figure 3-13., Output Carrier
1. Place Thrust Washer (4H) into counterbore of Carrier
(4A). BE SURE the small diameter side of Washer (4H) fac-
ing 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 0D of Carrier (4A).
6. Repeat Steps 1-5 for the installation of the two remain-
ing Planet Gears (4F).
Hub-spindle Assembly
NOTE: Refer to Figure 3-16., Hub Spindle
NOTE: Spray a light film of oil on all component parts during
assembly.
1. Place Hub (1 G) 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 instal-
lation.
2. Press Bearing Cup (1D) into hub using appropriate
pressing tool.
3. Turn hub over and press Bearing Cup (1D) into hub
using appropriate pressing tool.
4. Place Bearing Cone (1E), into Bearing Cup (1D).
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).
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 completely seated
in groove.
NOTE: Extra bearing pre-load caused by using tool in Step #9
must be removed. This should be done by placing 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.
