DRIVE BELT tension (fig.12)
To perform this check you need a special measurement instrument that that
provides a precise indication of the level of tension of the belt by means of a
frequency measurement.
Proceed as follows:
•
Open the door (D) (see fig.7).
•
Bring the microphone of the measurement instrument up to the belt at the
point indicated with “test” (about halfway) and strike the belt with a spanner.
•
Read the value detected by the instrument and if it is different from the
values indicated on the table, adjust the tension:
Higher value = belt too tight
Lower value = belt too loose
•
Loosen screws A to allow the attachment plate on which the screw unit is
fixed to slide, and use adjusting nut B to adjust the tension.
Turn the nut anti-clockwise to increase tension and clockwise to reduce tension.
Re-tighten screws A and check the frequency value; if necessary, repeat the
operation until the desired value has been reached.
EVERY 20000 HOURS
Replace the DRIVE BELT (fig.12)
Proceed as follows:
•
Open the door (D) (see fig.7) and remove the
protective panel of the belt/pulley compartment.
•
Loosen screws A to allow the attachment plate
on which the screw unit is fixed to slide.
•
Loosen nut B until the belt is completely
relaxed and remove it.
•
Fit the new belt and tighten it as described in
the previous section.
