Section 06 DRIVE SYSTEM
Subsection 01 (DRIVE BELT)

DRIVEN PULLEY NOTCHES
Turn the adjustment ring up to one notch, tighten
the screws, then rotate driven pulley to allow drive
belt to settle in pulley. Check height, if required
the adjustment ring can be turned up to 1/4 or 1/2
the notch. Check height, repeat as required.
NOTE: Notches are there on the driven pulley for
reference purpose only and the desired adjust-
ment can be attained at any point.
DRIVE BELT DEFLECTION
MEASUREMENT (reference only)
NOTE: The drive belt deflection measurement
must be performed each time a new drive belt
is installed. To obtain an accurate drive belt de-
flection measurement, it is suggested to allow a
break-in period of 50 km (30 miles).
Before checking the belt deflection, ensure vehi-
cle has the proper belt (refer to the APPLICATION
CHART).
Adjust pulley distance and alignment. Refer to
PULLEY DISTANCE AND ALIGNMENT.
To obtain maximum vehicle performance, the belt
tension must be adjusted according to specifica-
tions shown in the accompanying chart.

4. Deflection (read up)
1) Slide lower O-ring of deflection scale to speci-
fied measure.
2) Slide upper O-ring to 0 (zero) on the force scale.
3) Apply pressure until lower O-ring is flush with
edge of rule and read force on the upper scale
at top edge of O-ring.
