Measuring the CVT Sub-assembly Case Depth

Torque converter
housing

1. Temporarily install the torque converter
housing to the CVT case with two (2)
bolts at opposite corners, hand tight
(Figure 1M).


Use original bolts to secure.

Figure 1M

2. Reposition the CVT on the work bench
with the torque converter housing side
facing down (Figure 2M).
3. Clean and then zero the Digital Depth
Gauge (J-50272).
4. Set the Digital Gauge to millimeters.

Figure 2M

5. Clean the Gauge Block (J-50271).
NOTE: Only if a Gauge Block (J-50271)
is not available, measurement “X” (Figure
5M, page 56) will need to be determined
for the measuring bar being used. This
can be done either with a set of calipers
or with Digital Depth Gauge (J-50272).

Gauge Block
(J-50271)

6. Confirm the sealing surfaces of the CVT
case are clean.
7. Place Gauge Block (J-50271) across
sub-assembly sealing surface as shown
in Figure 3M.

8. Measure the average distance (Y) shown in Figure 5M as follows:


Refer to the Figures 4M and 5M and then proceed to page 57.



Measure only from areas that do not have any signs of contact.
IMPORTANT: Please refer to Figure 4M for acceptable areas (highlighted in green)
to measure “Y”.

Do not measure in this
area

Y = The distance between the upper surface of the Gauge Block and the surface where
snap ring seats.

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.


Upper board

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

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

NTB17-034i

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 the KIT
PARTS REFERENCE TABLE.

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
on 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.
