REAR WHEEL
TIP
When tightening the wheel axle nut, there
should be no clearance “a” between the adjust-
ing block “1” and adjusting bolt “2”.
8. Install:
• Rear wheel sensor
NOTICE
ECA21080
Make sure there are no foreign materials in
the rear wheel sensor rotor and rear wheel
sensor. Foreign materials cause damage to
the rear wheel sensor rotor and rear wheel
sensor.
TIP
When installing the rear wheel sensor, check the
rear wheel sensor lead for twists.
9. Measure:
• Distance “a”
(between the wheel sensor rotor “1” and rear
wheel sensor “2”)
Out of specification → Check the wheel bear-
ing for looseness, and the rear wheel sensor
and sensor rotor installation conditions
(warpage caused by overtorque, wrong in-
stallation direction, rotor decentering, LOC-
TITE® on the mounting surface of the rotor,
deformation caused by an impact during ser-
vice and caught foreign materials). If there is
any defective part, repair or replace the de-
fective part.
TIP
Measure the distance between the rear wheel
sensor rotor and rear wheel sensor in several
places in one rotation of the rear wheel. Do not
turn the rear wheel while the thickness gauge is
installed. This may damage the rear wheel sen-
sor rotor and the rear wheel sensor.
