SERVICE PROCEDURE

Precautions when Disassembling a CVT Assembly
Transmissions are vulnerable to particles (dust, metal, lint, etc.).
When disassembling a CVT, make sure your work environment (shop, workbench, etc.),
transmission area (sub-frame, oil pan, harness connector, etc.), and your hands are free of
contamination.
IMPORTANT:






Wash and clean the exterior of the CVT assembly prior to disassembling.
CAUTION: Cover all air breather and drive shaft holes to prevent water intrusion.
Apply rust penetrant to locator / dowel pins on torque converter housing and side
cover of CVT and allow to soak as needed.
Refrigerating oil seals may help in assembly (axle and T/C seals).
Only disassemble those parts which are mentioned in this bulletin.
Make sure all parts are clean prior to assembling / installing.
 Unpack service parts just before installation.



Store the related parts that have been
removed separately to prevent being
mixed up; small cups can be used.

Figure F

IMPORTANT: The CVT unit “wiring harness
connector” will be reused during this
procedure. The wiring harness can be
disconnected from the valve body at the
wiring harness connector and remain in the
CVT.



Before lifting the vehicle;




Place the transmission gear selector in Neutral.

Refer to the appropriate ESM, section TM – Transaxle & Transmission, for valve
body removal.

NOTE: The number ‘7’ is on the head of all bolts that need to be removed for valve
body removal. Do not remove any bolt that does not have the number ‘7’.
CAUTION: Never allow any chemicals or fluids other than NS-3 CVT fluid or
equivalent to enter the CVT assembly. Never allow any foreign debris, dust,
dirt, etc. to enter the CVT assembly.

4. Secure the front right tire with a suitable
strap.


This will assist in making the belt turn.

5. Mark the front left tire with a suitable
marking.


This will assure all 360° of the belt is
inspected.
Figure 2A

6. Using borescope J-51951 with mirror
attachment, inspect the entirety of the two
sides of the belt that come in contact with
the pulleys (see page 11, Figure 7A).
Reference the pictures on pages 11
through 15 for comparison.

NOTE:
 Be sure to remove the protective film

Step 6a

Clean the camera lens and mirror
before each inspection. Use 90%
isopropyl alcohol, and a lens swab
from Lens Swab packet J-51963 listed
in the PARTS INFORMATION.

Figure 3A

Before inspecting, make sure the
camera handle’s AA batteries are
fresh and the LCD monitor’s battery
is charged.

a. Insert the camera lens between the
CVT case and pulley where shown in
Figures 3A and 4A.


Step 6c

Camera

Insert the lens approximately seven
(7) inches, and then view the side
of the belt that contacts the pulley.

b. Slowly and carefully turn the front left
tire one full turn in the forward rotation
to view all of the belt.


Holding the borescope with one
hand allows for turning the tire with
the other hand (see Figure 5A).

CAUTION: If the tire is rotated in the
rearward rotation, the camera lens
may get caught between the belt and
pulley.
c. If the inspection result is OK, inspect
the other side of the belt.


Insert the camera lens in the
second location where shown
in Figure 3A and 6A, and then
perform step 6b again.

d. If the inspection result is OK 360° on
both sides of the belt, proceed to step
