Input Carrier Sub-Assembly
Input Carrier Sub-Assembly
1. Use the Input Planet Shaft (6) as a pressing tool to install the Planet Bushing (26) into the bore of each Planet Gear
(5). The shaft will help guide the bushing into the bore as well as prevent damage from the press.
2. Press three Input Planet Shafts (6) into the three holes of the Input Carrier (7). The head of the Input Planet Shaft
(6) needs to sit flush in the counterbore of the Input Carrier (7) hole
3. Insert Output Sun Gear (8) into the splined bore of the Input Carrier (7). The gear tooth end of the Output Sun
Gear (8) should protrude in the opposite direction of the Input Planet Shafts (6).
4. Using retaining ring pliers, install the Retaining Ring (24) into the groove of the Output Sun Gear (8). Make sure
that the Retaining Ring (24) is correctly seated in the groove and that the Output Sun Gear (8) cannot be pulled
out of the Input Carrier (7).
5. Place a Thrust Washer (25) on each side of the Input Planet Gear (5). Line up the bores as well as you can visu-
ally. Additional grease may help hold everything together.
6. Place the Input Planet Gear (5) and Thrust Washers (25) onto the Input Planet Shaft (6) sticking out from the Input
Carrier (7).
7. Repeat 5 & 6 for the other 2 Planet Gears.
8. Put the Thrust Plate (23) onto the three Input Planet Shafts (6). Use the three holes on the innermost bolt circle.
The other three holes are for a different gear ratio.
9. Using the appropriate retaining ring pliers put a Retaining Ring (18) into the groove of each Input Planet Shaft (6).
NOTE: Do not overstress the Retaining Rings (18).
