Press Bearing Cup (1C) into Housing (1G) taking care to
insure cup starts square with the bore of Hub (1G).
2.
Place Bearing Cone (1D) in Bearing Cup (1C) in Housing
(1G).
3.
Press or tap Seal (1B) Into the counterbore of Housing
(1G) to the point where it becomes flush with the Hous-
ing (1G) face. Care should be taken to insure Seal (1B) is
being correctly installed (smooth face up). Apply grease
to the rubber portion of the seal bore.
4.
Invert Hub (1G) and press Bearing Cup (1E) into counter-
bore of Housing (1G).
5.
Carefully lower Housing (1G) onto the Output Shaft (1A)
until Bearing Cone (1D) contacts the Output Shaft (1A).
6.
Press on the small end of the Bearing Cone (1D), being
careful not to contact the bearing cage, until the Bearing
Cone (1D) seats on the shoulder of the Output Shaft (1A).
7.
Start the Bearing Cone (1F) onto the Output Shaft (1A).
8.
Press or tap the Bearing Cone (1F) onto the Output Shaft
(1A) until it is just seated in the Bearing Cup (1E). while
rotating the Housing (G).
9.
Install Bearing Spacer (1H) onto Output Shaft (1A) and
against Bearing Cone (1F).
10.
Install Retaining Ring (1I) into the groove in the Output
Shaft (1A). This Retaining Ring (1I) should never be
reused in a repair or rebuild.
EYE PROTECTION SHOULD BE WORN DURING THIS PROCEDURE.

Carrier Assembly
NOTE:

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 the first row of 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).
5.
Place Carrier (3A) 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).
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.
8.
Slide the second Thrust Washer (3B) between the Cluster
Gear (3F) and the Carrier (3A) with the tang of the
washer located in the cast slot of the Carrier (3A). Finish
sliding the Planet Shaft (3E) through the Thrust Washer
(3B) and into the Carrier (3A).
9.
Position the non-chamfered side on the Planet Shaft (3E)
roll pin hole so that it is in line with the hole in the Carrier
(3A) using a 1/8” (3 mm) diameter punch.
10.
After using a 3/16” (5 mm) punch to align the two roll
pin holes. 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) out-
side diameter at the thrust washer (3B) tang. Use a 1/4”
(6 mm) pin punch to make sure the Roll Pin (3G) is flush
in the slot.
