Main Assembly Procedure

1. With the hub shaft sub-assembly resting on the shaft
(1A) install internal gear (2). The spline of the internal
gear (2) bore will mesh the spline of the output shaft
(1A).
2. Thrust Washer (11) is installed on the face of the output
shaft (1A). Sufficient grease or petroleum jelly should be
used to hold thrust washer in place.

3. Place O-ring (5) into hub counterbore. Use petroleum
jelly to hold O-ring in place. Also at this time locate and
mark the 4 counter beamed holes in the face of the hub
(1G). This is for identification later in the assembly.
BEWARE OF SHARP EDGES OF THE COUNTERBORE WHILE SEATING THIS O-
RING.
4. Thrust spacer (9) is installed into the bore of the output
shaft (1A). This should be a slip fit and thrust spaces
should rotate in this location.
5. Place carrier assembly (3) on a flat surface with the large
gears (3F) up and positioned as shown. Find the punch
marked tooth on each large gear (3F) and locate at 12
o'clock (straight-up) from each planet pin. Marked tooth
will be located just under the carrier (3A) on upper two
gears (3F).
