Deflection
3. If it is outside the standard value, re-adjust belt tension.
<When using MUT-II>
(1) Connect the special tool (MB991668) to the MUT-II.
(2) Connect the special tool (MB991704) to the MUT-II
and the battery.
(3) Rotate the crankshaft clockwise for two rounds to
position No.1 cylinder at compression TDC and check
that timing marks of each sprocket are aligned with
each other.
(4) Select "Belt Tension Measurement" from the menu
screen of the MUT-II.
(5) Hold the special tool (MB991668) to the middle of
the belt between sprockets (at the place indicated
by the arrow) as shown in the illustration about 10
- 20 mm away from the rear surface of the belt and
so that it is perpendicular to the belt (within an angle
of ±15_).
(6) Gently tap the middle of the belt between sprockets
(the place indicated by the arrow) with your finger
as shown in the illustration and check that the vibration
frequency of the belt is within the standard value.
Caution
1) If strong gusts of wind blow against the
microphone or if there are any loud sources
of noise nearby, the values measured by the
microphone may not correspond to actual
values.
2) If the microphone is touching the belt while
the measurement is being made, the values
measured by the microphone may not
correspond to actual values.
<When checking the deflection>
Apply a force of approx.100N to the middle (arrow part)
of pulley shown in the figure, and check that the deflection
is within the standard value.
