BRP SUMMIT - Drive Belt Deflection Measurement (Reference Only)

Section 08 DRIVE SYSTEM
Subsection 01 (DRIVE BELT)
DRIVEBELTDEFLECTION
MEASUREMENT (REFERENCE
ONLY)
NOTE: The drive belt deflection measurement
must be performed each time a new drive belt is
installed.
NOTE: To obtain an accurate drive belt deflection
measurement, it is suggested to allow a break-in
period of 50 km (30 miles).
Before checking the belt deflection, ensure vehi-
clehastheproperbelt(refertotheAPPLICATION
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.

1. Mark specified deflection
Using spring scale and stick, apply specified force
on drive belt halfway between pulleys as shown.

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.
