MAINTENANCE
General Maintenance
Clutch Alignment and Offset
Clutch center distance and
alignment (A) are crucial to
maintaining optimum
performance. See your Owner’s
Manual Supplement for the
recommended offset between the
drive and driven clutches with the
belt removed.
The drive belt is a very important
part of the drive system. Belt
width and length must match the
center distance of the clutches
and sheave width of the drive
clutch. For this reason, Polaris
recommends that only O.E.M.
belts be used. Other belts may
match the dimensions, but can
drastically change the shift
pattern, resulting in poor
performance. See your dealer for
service and adjustments.
NOTE: A worn belt will continue to function, but will not deliver
maximum performance. Always carry a spare belt in case of an emer-
gency. See page 132 for belt removal and installation.
Drive Belt Deflection
Measure belt deflection with
both clutches at rest and in their
full neutral position.
Place a straight edge on the belt
(A) and apply downward
pressure while measuring at
point B. This measurement
should be 1 1/4”.
