Tech Tip #1: Belt Deflection
(Tension)
Belt deflection is very critical
for proper clutch performance. If your deflection is too tight,
the belt will burn on the clutch hub and you will lose top end. If
the belt is too loose, it will allow the primary clutch to upshift
faster then the secondary clutch causing a low end bog and poor
performance.
To check your belt deflection,
you will need a straight edge and a tape measure. Normally you
want your belt to stick out of the secondary clutch 1/16" - 1/8"
if possible. Lay a straight edge on the belt and measure the
distance between the straight edge and the belt between the two
clutches. Lightly press down on the belt to remove any slack. Most
machines use a spec of 1 1/8" to 1 1/4" of belt deflection. If you
measure less than 1 1/8", your belt is too tight. If you measure
more than 1 1/4" your belt is too loose. This procedure should be
shown in your owners or service manual.
Factory specs are: Polaris 1
1/4", Arctic Cat 1 1/8"-1 1/4", and Ski-Doo 1 1/4".
Look at your manuals to see how
to adjust belt deflection. Anytime you change your belt, your
deflection can change. Remember, when you put on a new belt, it
will stretch after awhile and the deflection will need to be
reset.
