Input Carrier Sub-Assembly
1. Use the Input Planet Shaft (G6) as a pressing tool
to install the Planet Bushing (G26) into the bore of
each Planet Gear (G5). The shaft will help guide the
bushing into the bore as well as prevent damage
from the press.
2. Press three Input Planet Shafts (G6) into the three
holes of the Input Carrier (7). The head of the Input
Planet Shaft (G6) needs to sit flush in the counter
bore of the Input Carrier (G7) holes
3. Insert Output Sun Gear (G8) into the splined bore
of the Input Carrier (G7). The gear tooth end of the
Output Sun Gear (G8) should protrude in the oppo-
site direction of the Input Planet Shafts (G6).
4. Using retaining ring pliers, install the Retaining Ring
(G24) into the groove of the Output Sun Gear (G8).
Make sure that the Retaining Ring (G24) is cor-
rectly seated in the groove and that the Output Sun
Gear (G8) cannot be pulled out of the Input Carrier
(G7).
5. Place a Thrust Washer (G25) on each side of the
Input Planet Gear (5). Line up the bores as well as
you can visually.
6. Place the Input Planet Gear (G5) and Thrust
Washers (G25) onto the Input Planet Shaft (G6)
sticking out from the Input Carrier (G7).
7. Repeat 5 & 6 for the other 2 Planet Gears (G5).
8. Put the Thrust Plate (G23) onto the three Input
Planet Shafts (G6). Use the three holes on the out-
ermost bolt circle. The other three holes are for a dif-
ferent gear ratio.
9. Using the appropriate retaining ring pliers put a
Retaining Ring (G18) into the groove of each Input
Planet Shaft (G6).
NOTE: NOTE: Do not overstress the Retaining Rings (G18).
