place during assembly.
2. Install the first row of 14 Needle Rollers (3C) into the
bore of Cluster Gear (3F).
3. Insert Spacer (3D) into bore of Cluster Gear (3F) on top of
the Needle Rollers (3C).
4. Place second row of Needle Rollers (3C) into bore of
Cluster Gear (3F) against Spacer (3D) and remove Planet
Shaft (3E).
5. Place Carrier (3A) into tool fixture so that one of the roll
pin holes is straight up.
6. Start Planet Shaft (3E) through the hole in Carrier (3A).
Using ample grease to hold it in position, slide one
Thrust Washer (3B) over the Planet Shaft (3E) with the
tang resting in the cast slot of the Carrier (3A). Place Ball-
Indented Thrust Washer (3H) on the Planet Shaft (3E)
with the indents against the first washer.
7. 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.

Planet Shaft with the indents against the second thrust
Washer. Finish sliding the Planet Shaft (3E) through the
Thrust Washers (3H) & (3B) and into the Carrier (3A).

roll pin hole so that it is in line with the hole in the Car-
rier (3A) using a 1/8" (3 mm) diameter punch.
