Drive Belt Deflection Measurement (Reference Only) - BOMBARDIER ski-doo Tundra Scandic 2004 Series Shop Manual

Allen screws must be restrained while tightening
jam nut to prevent throwing adjustment out. Use
drive belt tension adjuster (P/N 529 008 700).
TYPICAL
All Models
Vary pulley distance — within tolerances — to ob-
tain proper drive belt height.
DRIVE BELT DEFLECTION
MEASUREMENT (reference only)
IMPORTANT: The drive belt deflection will be au-
tomatically set after performing the pulley dis-
tance and belt height adjustments. The following
procedure will confirm proper pulley distance and
belt height adjustment.
NOTE: To obtain an accurate drive belt deflection
measurement, it is suggested to allow a break-in
period of 50 km (30 mi.).
Before checking the belt deflection, ensure that a
good-condition proper belt (Refer to the APPLICA-
TION CHART) is installed.
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.
