7. Install the exhaust pipe on the manifold and resonator.
8. Install all the exhaust springs.
Too high on initial engagement

Belt deflection is critical for optimum belt performance and
belt life. It should be checked at 500 miles (800km) and then
in 1000 mile (1600km) increments after that.
Too much belt deflection is when the belt is too long or the
center distance is 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 engagement
(A).
Not enough belt deflection (B) is when the belt is too short or
the center distance is too long. The initial starting ratio will be
too low. In addition, the machine may creep when the engine
idles, causing damage to the internal face of the drive belt.

MEASURING BELT DEFLECTION

1. Measure the belt deflection with both clutches at rest and
in their full neutral position.
2. Place a straight edge across the tow clutches, on top the
belt.
3. Apply downward pressure to the belt and measure the
distance at point (D).
4. The measurement should be 1 1/4" (3.2cm).
5. If the measurement is not correct adjust driven clutch, See
"TEAM BELT DEFLECTION" on page 26.

LUBRICATION

GREASE POINTS

NOTE: A grease gun kit (PN 2871312) comes with
grease and adapters to lubricate all the fittings
needed to service Polaris snowmobiles.
Lubricate the following fittings with Polaris Premium All
Season grease every 1000 miles (1600 km) and before summer
storage. When applying grease to these points, free up all the
weight form the component being greased to permit better
penetration.
• Ski spindles
• Ski pivots
• Steering post pivots
• Rear suspension pivot shafts
• Jackshaft
• Driveshaft

JACKSHAFT BEARING

1. Loosen the driven clutch retaining bolt and pull the clutch
away form the flange fitting to expose the bearing grease
point.
2. Apply grease with the grease gun with just a few pumps.
3. Install the driven clutch see "DRIVEN CLUTCH
INSTALLATION" on page 7.20.
