SECTION 3 - CHASSIS & TURNTABLE

Carrier Assembly

Refer to Figure 3-43.
1. Apply a liberal coat of grease to the bore of Cluster Gear
(3F). This will enable the Needle Rollers (3C) to be held in
place during assembly.
2. Install one half of the inside of the Cluster Gear (3F) with
16 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 that form the space, and then slid
parallel to the other rollers into place.
3. Place one Spacer (3D) on top of the Needle Rollers (3C)
inside the Planet Gear (3F).
4. Install the other half of the Cluster Gear (3F) with16 Nee-
dle Rollers (3C).
5. Place Carrier (3A) into tool fixture so that one of the roll
pin holes is straight up.
6. Start Planet Shaft (3E), with end opposite roll pin hole
first, through the planet shaft hole in carrier (3A), mak-
ing sure that the roll pin hole with the large chamfer in
the planet shaft is straight up.

7. Using ample grease to hold them in position, locate
Thrust Washer (3B) onto each side of interior carrier wall
with tangs located into slots in Carrier pads.
8. With large end of Cluster Gear (3F) facing the roll pin
hole in the Carrier, place the Cluster Gear into position in
Carrier (3A) and push Planet Shaft (3E) through the Clus-
ter Gear (3F) without going all the way through the car-
rier (3A).
9. Finish sliding the Planet Shaft (3E) into the Carrier (3A)
until roll pin holes of planet shaft and carrier are aligned.
Align roll pin hole using a 1/8 in. diameter punch.
NOTE: The chamfer on the Roll Pin hole should be towards the roll
pin hole in the Carrier.
10. Drive the roll pin (3G) through Carrier (3A) and into the
Planet Shaft (3E) until the Roll Pin (3G) is flush with the
bottom of the cast slot in the Carrier (3A) outside diame-
ter at the Thrust Washer (3B) tang. Use a 1/4" pin punch
to make sure the roll pin (3G) is flush in the slot.
11. Repeat Steps 6 through 10 for the remaining two Cluster
Gears (3F).
