7.

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

Holding the borescope with one
hand allows for turning the tire with
the other hand (see 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.
 If the inspection result is NG, replace the CVT sub-assembly (page 18), control valve
(page 74) and, if applicable, reprogram the TCM (page 81).

CVT Assembly Removal
Overview of Sub-assembly Repair
Steps 1-15 below are an overview of the CVT sub-assembly repair. The procedure for this
bulletin continues on the next page with step 9.

1. Apply rust penetrant as necessary to the dowel pins on the converter
housing side and sub-assembly side cover.
2. Remove the CVT from the vehicle.
3. Remove the Converter Housing, Oil Seals, Oil Pump Cover, Oil Pump and
Oil Filter.
4. Clean the CVT case surfaces.
5. Clean the Oil Passages in the CVT Case, Oil Pump Cover, and CVT Filter
Area.
6. Check initial pulley movement characteristics.
7. New Pump Installation
8. Replace the Side Cover – Pulleys and Belt.
9. Confirm shift selector movement.
10. Recheck new pulley movement characteristics matches that of the original
assembly.
11. Clutch Total Endplay Adjustment – Thrust Bearing Selection
12. Clean the Converter Housing Passages.
13. CVT Reassembly
14. Control Valve, Strainer, and Pan Installation
15. Install the CVT Assembly.
HINT: For additional information review video # 547: “CVT Belt and Pulley
Replacement”.

9.

Temporarily install the oil pan gasket and oil pan with four oil pan bolts at the corners
of the oil pan, hand tight (Figure 24).
HINT: It is not necessary for the control valve to be installed, a new one will be
installed later in the service procedure.

Figure 24

10.

Remove the CVT from the vehicle.


For CVT removal, refer to the ESM: section TRANSMISSION & DRIVELINE TRANSAXLE & TRANSMISSION - CVT: RE0F10D - UNIT REMOVAL AND
INSTALLATION - TRANSAXLE ASSEMBLY.

To avoid seal damage or deformation on AWD vehicles, use extreme care when moving
the axle in or out of the transfer case assembly. Properly support and guide the axle.

19/100

NTB20-091

11.

Place the CVT on a workbench with
the oil pan side down.

Use wood or plastic blocks to keep the CVT
steady and to prevent deformation to the oil
pan.

12.

Remove the torque converter.

13.

Drain the torque converter.

Remove the Converter Housing, Oil Seals, Oil Pump Cover, Oil Pump and Oil Filter

15.

Remove all 23 converter housing
mounting bolts (see Figure 28).
HINT:


These bolts will be replaced with
new ones and will not be reused.



Use a short socket on the bolts
indicated by



Apply rust penetrant to the dowel
pin if needed.

Separate and then remove the converter housing from the CVT case.


Use Slide Hammer J-25721-A and Slide Hammer Bolt J-50255-UPD with J-Hook
J-51923 at the cut-out areas similar to the one shown in Figure 29 and Figure 30.

To avoid damage to the vehicle DO NOT use a pry-bar, chisel, etc. to separate the
converter housing from the CVT case.

Lift the dummy cover from the sides ONLY. Do NOT lift from the input shaft
(Figure 47). This can lift the clutch pack out.



Do NOT remove the lathe cut seals (white seals in Figure 48) from the dummy
cover. These seals will be reused.



Lathe cut seals must be in their correct positions during final assembly to
prevent drivability issues.

HINT:
 Take care when removing the
thrust bearing so that the lathe cut
seals are not knocked out of their
grooves.




Thrust bearing
The thrust bearing has two
different sides. As the thrust
bearing is removed, note the thrust
bearing orientation so that the new
bearing can be installed in the
same orientation.
