HINT: The outer cardboard of the
shipping box can be disassembled
for easy removal of the sub-assembly
by removing the shipping tape.

108. Locate the plastic bag that contains
the snap rings (Figure 143).


There are six (6) individual snap
rings in the plastic bag.



Take the plastic bag out of the
shipping box, and put aside on
the work bench.

HINT: See Reference # 5 in the KIT
PARTS REFERENCE TABLE on
page 149.

109. Take the new sub-assembly out of
the shipping box and place it on the
work bench.
To avoid possible damage to the
CVT:


Hold the sub-assembly by the
side cover ONLY when removing
it from the shipping box.



DO NOT handle the belt or
pulleys of the sub-assembly when
removing from the shipping box.



New sub-assembly

110. Take the lower board with foam cushion (lower board) out of the shipping box shown
in Figure 146.
HINT: Step 111 is for kits that have a
separate spacer (Figure 145). In later kits
this spacer will be part of the lower board
and step 111 will not be used.
111. Take the spacer (Figure 145) out of
the shipping box and place it on the
work bench where the sub-assembly
will be installed, and then place the
lower board on top of the spacer as
shown in Figure 146.

Spacer

Figure 145

HINT: The spacer will be the last
item that is removed from the
shipping box and is approximately 1
inch thick.


Position the lower board so that it hangs over the spacer.



Align the lower board so that the left and the right cut-outs are even with the
spacer.

HINT: The positioning of the lower board with foam cushion will allow the CVT case
enough clearance from the work bench to allow it to seat flush with the subassembly.
