SERVICE PROCEDURE
IMPORTANT: Repairs performed for this bulletin require CONSULT-III plus diagnostic
result reporting function-setting to be ON and Diagnosis (All Systems) to be performed. If
not done, it may result in a repair being non-warrantable.

E.

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.

To avoid damage to the CVT:




Wash and clean the exterior of the CVT assembly prior to disassembling to prevent
debris and contamination from entering.
Cover all air breather and drive shaft holes to prevent water intrusion.
Make sure all parts are clean prior to assembling / installing to prevent debris and
contamination from entering.

HINT:
 Refrigerating oil seals may help in assembly (axle and T/C seals).
 Unpack service parts just before installation.
 Apply rust penetrant to locator / dowel pins on the torque converter housing and side
cover of the CVT and allow to soak to help with disassembly.



Store the related parts that have
been removed separately to prevent
being mixed up; small cups can be
used.
 Unpack service parts just before
installation.

HINT: The CVT unit wiring harness
connector will be reused during this
procedure. The wiring harness can be
disconnected from the control valve at the
wiring harness connector and remain in the
CVT.



Refer to the ESM: TRANSMISSION & DRIVELINE - TRANSAXLE &
TRANSMISSION - CVT: RE0F10D - REMOVAL AND INSTALLATION CONTROL VALVE

HINT: The number ‘7’ is on the head of all bolts that need to be removed for control
valve removal. Do not remove any bolt that does not have the number ‘7’.

To prevent damage to the CVT, 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.

Secure the passenger (RH) front tire
with a suitable strap, so that it cannot
rotate.


5.

This will assist in making the belt
turn.

Mark the driver (LH) tire with a suitable
marking.


This will ensure all 360° of the belt
are inspected.

6.

Using borescope J-51951 with its
mirror attachment, insert the camera
lens between the CVT case and pulley
(Figure 10 and Figure 11).

Belt
Pulley
Case

 Insert the lens approximately seven
(7) inches, and then view the side
of the belt that contacts the pulley.
HINT:
 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 on page 85.

7.

Inspect the entire side of the belt by,
slowly and carefully, turning the driver
front tire one full rotation in the forward
direction.


Holding the borescope with one
hand allows for turning the tire with
the other hand (Figure 13).



Reference the Figures on pages
14 through 17 for a comparison
of an OK and NG belt condition.

HINT: If the tire rotates in the rearward
direction, the camera lens may be
caught between the belt and pulley.

Figure 13

 If the inspection result is OK, inspect the other side of the belt in step 8 on
page 13.
 If the inspection result is NG, replace the CVT sub-assembly (page 18) and
control valve (page 73).
