4. Secure the front right tire with a suitable
strap, so that it cannot rotate.


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 10

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 12, Figure
15).
 Reference the Figures on pages 12
through 16 for comparison of an OK
and NG belt condition.

NOTE:
o Be sure to remove the protective film
from the mirror before the first use.
o 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.
o Before inspecting, make sure the
camera handle’s AA batteries are
charged and the LCD monitor’s
battery is charged.

a. Insert the camera lens between the

CVT case and pulley where shown in
Figure 11 and Figure 12.
 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 13).

CAUTION: If the tire is rotated in the
rearward rotation, the camera lens
may get caught between the belt and
pulley.
Figure 13

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 11 and Figure 14, and
then perform step 6b again.

d. If the inspection result is OK 360° on

both sides of the belt, proceed to

7. If the belt inspection result is OK, replace only the valve body, and then reprogram the
TCM if applicable.


For valve body replacement, go to page 71, Control Valve (Valve Body) Strainer
and Pan Installation.



Check TCM part number (step 139 on page 79) and if needed perform
reprogramming (step 139 on Page 79) if applicable.
IMPORTANT: Reprogramming, if needed, must be done before performing
additional services.

8. If the belt inspection result is NG, replace the CVT sub-assembly and valve body, and
then check step 139 on page 79 to confirm if a TCM reprogram is available.


Go to CVT Assembly Removal, page 17.
