Belt Deflection; Measuring Belt Deflection - Polaris 2003 Pro X Service Manual

Belt Deflection

Too much belt deflection - If the belt is too long or the
center distance too short, the initial starting ratio will be
too high, resulting in performance loss. This is due to the
belt rising too high in the drive clutch sheaves upon en-
gagement.
Not enough belt deflection (belt too tight) - If the drive
belt is too short or the center distance too long, the ratio
will again be incorrect. In addition, the machine may
creep when the engine idles, causing damage to the in-
ternal face of the drive belt.

Measuring Belt Deflection

IMPORTANT NOTE: Do not apply excessive pressure to force belt into driven sheaves. This will result in an
improper measurement. If belt deflection cannot be adjusted within specification using methods below, inspect
center distance and compare to specifications on page 5.30.
1. Measure belt deflection with both clutches at rest and
in their full neutral position.
2. Place a straight edge on the belt and apply downward
pressure while measuring at the point shown.
