CVT Belt Visual Inspection

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

This will assist in making the belt turn
during the borescope belt inspection
step.

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

This will assure all 360° of the belt is
inspected.
Figure 1C

3. Using the steps on pages 13-18 inspect the entirety of the two sides of the belt that
come in contact with the pulleys (see Figure 2C):
IMPORTANT:
 Reference the pictures on pages 19-22 for comparison.
 Use borescope J-51951 with mirror attachment.
 Be sure to remove the protective film from the mirror before the first use.
 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 PARTS
INFORMATION.
 Before inspecting, make sure the camera handle’s AA batteries are fresh and the
LCD monitor’s battery is charged.

a. Install the Clutch Engagement Tool (J-52273) to the CVT case with two bolts where
shown in Figure 3C finger tight.


Bolt torque not to exceed: 2.26 N•m (0.23 kg-m, 20 in-lb.)
CAUTION:
 Do not over torque the bolts. The threads are easily damaged.
 Make sure an O-ring is installed to the Clutch Engagement Tool (J-52273)
before installation.

NOTE: The O-ring for the Clutch Engagement Tool comes with the attachment. To
obtain only the O-ring, refer to PARTS INFORMATION for the part number.

IMPORTANT:


Proper pressure has been
achieved when the CVT belt
moves while the left front wheel
is rotated and the vehicle is in
NEUTRAL with the right front
wheel secured.



Do NOT over pressurize the
system as internal damage to
the CVT could result.



moving with tire rotation.
 Pressure will be retained.

c. Insert the borescope where shown in Figure 5C as follows:
I.

Face the mirror of the borescope toward the driver’s side of the vehicle (CVT
side cover).

II.

Insert the lens approximately 7.5 inches from the CVT oil pan gasket surface
as shown in Figure 6C on page 15.



Holding the borescope (camera

rotation of the tire with the other
hand (see Figure 7C).



If evidence of belt slip is identified
as shown on pages 18-21, skip to
step 5 on page 23.



If the belt does not move when
rotating the front left tire, return to
step 3b on page 13.

e. If the inspection result confirms that no slippage has occurred on the observed side,
inspect the other side of the belt as follows:
I.

Print page 16 and then shape the borescope camera flexible tube like the image
in Figure 8C.

Holding the borescope (camera flexible tube) with one hand allows rotation of the
tire with the other hand (see Figure 7C).
IMPORTANT: If the belt does not move when rotating the front left tire, supply
additional air with hand pump (J-45664) to re-engage the clutch as necessary.



Look for evidence of belt slip as shown on pages 18-21.

g. Remove the Clutch Engagement Tool (J-52273) from the CVT.
CAUTION: The remaining CVT fluid may spray when the Clutch Engagement Tool is
removed. Place a rag over the Clutch Engagement tool and SLOWLY loosen the two
bolts until the audible depressurization is noted.

h. Is the inspection result OK (no evidence of slip) for 360° rotation of both sides of the
belt?
YES: Go to step 4 on page 23 (No Belt Damage).
NO: Go to step 5 on page 23 (Belt Damaged).
