Input Carrier Assembly
NOTE: Refer to Figure 3-15., Input Carrier.
1. Apply a liberal coat of grease to the bore of one Input
Planet Gear (3F).
2. Line the inside of the Planet Gear (3F) with 14 Needle
Rollers (3C).
NOTE: The last roller installed must be installed end wise. That is,
the end of the last roller must be placed in between the
ends of the two rollers which form the space, and then slid,
parallel to the other rollers, into place.
3. Set Carrier (3A) in an upright position.
4. Insert a Planet Shaft (3E) into the planet shaft hole in the
end of the Carrier (3A) opposite the splined end. The
end of the planet shaft that does NOT have the roll pin
hole should be inserted into the carrier FIRST.
5. Place one Thrust Washer (3B) onto the end of Planet
Shaft (3E). Make sure the flat faces towards the inside of
the carrier and make sure the button fits in the pocket
on the inside of the Carrier (3A) towards the OD.
6. Following the thrust washer, place Planet Gear (3F) with
needle rollers, onto Planet Shaft (3E).
7. Following the planet gear, place one more Thrust
Washer (3B) onto Planet Shaft (3E). Align the Thrust
Washer (3B) in the same manner described in Step 5.
8. Now insert Planet Shaft (3E) through the opposite
planet shaft hole on Carrier (3A). Use an alignment
punch or similar tool to align the roll pin holes on Carrier
(3A) and Planet Shaft (3E).
NOTE: Be sure not to hit the Planet Gears (3F) when driving in the
Roll Pins (4G).
9. Drive Roll Pin (4G) down into the aligned roll pin holes.
Pin should be flush with the flat of carrier.
10. Repeat Steps 1-9 for the installation of the two remain-
ing Planet Gears (3F).
NOTE: Some grease may need to be applied to the Thrust Washers
(3B) to hold them in place while installing the planet gears.
Output Planet Gear Assembly
NOTE: Refer to Figure 3-14., Planet Gear.
1. Apply a liberal coat of grease to the bore of one Output
Planet Gear (4F).
2. Line the inside of the Planet Gear (4F) with 14 Needle
Rollers (4C).
NOTE: The last roller installed must be installed end wise. That is,
the end of the last roller must be placed in between the
ends of the two rollers which form the space, and then slid,
parallel to the other rollers, into place.
3. Place Spacer (4D) into the bore of the Output Planet (4F).
4. Repeat Step 2 to put in second roll of Needle Rollers
(4C).
5. Apply grease to hold two Thrust Washers (4B) together
and onto Output Planet Gear (4F) counterbore. Do the
same to the other side.
6. Repeat Steps 1-5 to finish the assembly of the two
remaining Output Planet Gears (4F).
