Gear (3F).
3. Insert Spacer (3D) in bore of Cluster Gear (3F) on top of
Needle Rollers (3C).

ter Gear (3F) against Spacer(3D).
5. Place Carrier (3A) with one roll pin hole straight up.
6. Start Planet Shaft (3E) through hole in Carrier (3A). Using
ample grease to hold it in position, slide one Thrust
Washer (3B) over Planet Shaft (3E) with tang resting in
cast slot of Carrier (3A).

Carrier, place Cluster Gear in position in Carrier (3A).

pin (3G) through Carrier (3A) and into Planet Shaft (3E)
until Roll Pin (3G) is flush with bottom of cast slot in Car-
rier (3A) outside diameter at Thrust Washer (3B) tang.
Use a 1/4" pin punch to make sure roll pin (3G) is flush in
