Pulse Rotor Inspection
4.

Check for looseness in the pulse rotor using tools J-52728 Pulse Rotor Lock and
J-52729 Wheel Lug Torque Adapter Set.
Secondary
a. Remove the secondary speed sensor.
speed sensor
Refer to the Electronic Service
Manual (ESM), section TM –
Transaxle & Transmission >
CVT:RE0F11A > Removal And
Installation > Secondary Speed
Sensor.

Figure 20C
b. Install Pulse Rotor Lock Tool J-52728 into the secondary speed sensor hole and
tighten the bolt to 5.9 N•m (0.60 kg-m, 52 in-lb).
c. Using Wheel Lug Torque Adapter Set (J-52729-1) and an appropriate torque
wrench, apply torque to the driver’s side (LH) front wheel.

d. Smoothly apply a maximum torque of
25 N•m (18 ft-lbs) in a forward driving
direction (Counter-clockwise at
driver’s side (LH) front wheel).
 A slight movement in the front
wheel is considered normal due to
gear lash.

Driver’s Side (LH)
Figure 21C
e. Was maximum torque (18 ft-lbs) achieved without wheel spin in a forward direction?
 YES: Continue to step f. on page 28.
 NO: Skip to step h. on page 28.

f. Smoothly apply a maximum torque of
25 N•m (18 ft-lbs) in a reverse driving
direction (Clockwise to the driver’s
side (LH) front wheel).

Driver’s Side (LH)

 A slight movement in the front
wheel is considered normal due to
gear lash.

Figure 22C

g. Was maximum torque (18 ft-lbs) achieved without wheel spin in either direction?
 YES: Skip to step 5 on page 29.
 NO: Continue to step h.
h. If the driver’s side (LH) front wheel spins in either direction, check the following:
 Ensure the passenger’s side (RH) front wheel is not moving when applying
torque as referenced in step d and f.
 If the passenger’s side (RH) front wheel is moving, check that the strap securing
the passenger’s side (RH) front wheel is secure.
 If the CVT belt is NOT moving while the wheel spins return to step 3b on page 17
and verify the clutch engagement tool is at 30 PSI.
i. If the driver’s side (LH) front wheel still spins in either direction after checking all of
the possible causes in step h, a loose pulse rotor is confirmed. Skip to step 9 on
page 29.
