RING (1I), O-RINGS (5) AND SEAL (1B) SHOULD ALWAYS BE
REPLACED.

Main Assembly Procedure

1. With the hub shaft sub-assembly resting on the shaft
(1A) install internal gear (2). The spline of the inter-
nal gear (2) bore will mesh the spline of the output

put 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 petro-
leum 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.
4. Thrust spacer (9) is installed into the bore of the out-
put 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 0'clock (straight-up) from each planet
pin. Marked tooth will be located just under the car-
rier (3A) on upper two gears (3F).
