3. Confirm that the tensioner B centre and bolt centre are
positioned as shown in the illustration.
4. Apply tension on the timing belt by lifting tensioner B
in the direction of the arrow with a finger, and tension
the tension side until it is “tight”. Fix tensioner B in this
state by tightening the bolt.
NOTE
Make sure that the tensioner B shaft does not rotate
when tightening the bolt. If the shaft rotates, the timing
belt becomes too tense.
5. Connect the special tool (MB991704) to MUT-IIand the
battery.
6. Connect the special tool (MB991668) to MUT-II.
7. Rotate the crankshaft clockwise two turns, and align each
timing mark.
8. Select “Belt Tension Measurement” from the MUT-IImenu
screen.
9. Separate the special tool (MB991668) 10 to 20 mm from
the centre back between the sprockets (shown with an
arrow), and hold so that it is vertical (inclination within
±15_) in respect to the belt.
10. Lightly tap the section shown with an arrow with fingers,
and measure the belt vibration frequency. If the results
are deviated from the standard value, loosen the bolt,
tension the belt again, and then measure the vibration
frequency again. Repeat this step until the standard value
is attained. Tighten the bolt when the standard value
is attained.
