New Snap Ring Selection and Installation to the New Sub-assembly

Top of the
shipping box
1. Remove the top of the shipping box of
the new sub-assembly.
NOTE: Outer cardboard of the shipping
box can be disassembled for easy
removal of the sub-assembly by
removing the shipping tape.

Figure 1N

2. Remove the upper board with foam
spacer assembly.


Packing material may be different
then what is shown in Figure 2N.

Upper board

3. Locate the data sheet in the shipping box
and place it in a safe place.


This data sheet is required for snap
ring selection in the following steps.

Figure 3N

NTB17-034

4. Locate the plastic bag which contains the
snap rings (Figure 4N).


There are six individual snap rings in
the plastic bag.



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

NOTE: See Reference # 5 in KIT
PARTS REFERENCE on page 105.
Figure 4N

5. Take the new sub-assembly out of the
shipping box and place it on the work
bench.
CAUTION:


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.



DO NOT BREAK the foam cushion
in the shipping box. This will be
used as a stabilizer for the subassembly during the repair.

6. Take the lower board with foam cushion (lower board) out of the shipping box (Shown in
Figure 7N).
IMPORTANT: Step 7 is for kits that have a
separate spacer (Figure 6N). In later kits
this spacer will be part of the Lower
board and step 7 will not be used.
7. Take the spacer (Figure 6N) out of the
shipping box and place on the work
bench where the sub-assembly will be
installed, and then place the lower board
top of the spacer as shown in Figure 7N.
NOTE: The spacer will be the last item
that is removed from the shipping box
and is approximately 1 inch thick.

Spacer

Figure 6N



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



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

NOTE: 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 sub-assembly.

8. Remove the sub-assembly from the
plastic bag.

9. Place the new sub-assembly onto the
lower board.


The sub-assembly must be level and
oriented as shown in Figure 8N for
proper seating of the CVT case later
in this procedure.

13. Open the plastic bag (with snap rings) that was removed from the shipping box in step
4, and then choose the correct Part Number selected from Table A.
NOTE: There are six individually packed snap rings in the plastic bag. See Reference #
5 in KIT PARTS REFERENCE on page 105.
14. Measure the new snap ring and confirm its thickness is equal to the Snap Ring
Reference in Table A.
15. Install the selected snap ring to the secondary pulley front bearing of the new subassembly.
NOTE: Discard unused snap rings.

NOTE: Sealant will be applied between
these components at a later step.
a. Slowly lower the CVT case onto the
sub-assembly.
IMPORTANT:


Only use the weight of the
CVT case when installing it to
the sub-assembly.



Do NOT use any other
external force to seat the CVT
case to the sub-assembly.

e. If the CVT case will not seat on the
sub-assembly:
1) Access the counter driven gear
through the top of the CVT case,
and
2) Rotate the counter driven gear on
the primary pulley back and forth.
NOTE: This will allow the splines
of the secondary pulley and the
planetary carrier plate to align.

f. Confirm that the mating surface of the CVT case is seated to the sub-assembly
completely.


If the CVT case does not sit completely flush with the sub-assembly, DO NOT
apply any vertical force to seat it.
1) If this occurs, first lift the CVT case up slightly and then lower.
2) Repeat until the CVT case and sub-assembly sit flush with each other.
