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
Output Shaft (1A). This should be a slip fit and the
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 Car-
rier (3A) on upper two gears (3F).
6. With shoulder side of Ring Gear (4) facing down,
place Ring Gear over (into mesh with) large gears.
Be sure that punch marks remain in correct location
during Ring Gear installation. The side of the Ring
Gear with an X stamped on it should be up.
7. While holding Ring Gear (4) and Cluster Gears (3F)
in mesh, place small side of Cluster Gears (3F) into
mesh with the Internal Gear (2) and Input Gear (13).
On the Ring Gear locate the hole marked X over one
of the marked counterbored holes (Step 3) in Hub
(1G).
NOTE: If gears do not mesh easily or Carrier Assembly does
not rotate freely, then remove the Carrier and Ring
Gear and check the Cluster Gear timing.
