Engine Cooling System Overview

The engine cooling system consists of the following
components:

• Water Pump

• Water Inlet / Outlet Manifolds

• Thermostat

• Front Tunnel, Left and Right-Hand Perimeter and Rear 

Tunnel Cooling Extrusions

• Front Radiator

• Expansion Tank / Coolant Fill Tube

The cooling system is filled via the designated main fill tube, not
the expansion tank.

PVT / DRIVE SYSTEM MAINTENANCE

Drive Belt Deflection

1.

Measure the belt deflection with both clutches in their full
neutral position.

2.

Place a straight-edge across the clutches, and on top the
belt.

3.

Pull the belt down and measure the distance between the
straight-edge and top of belt.

4.

The measurement should be no more than 1 1/4” (3.2cm).

Chaincase Chain Tension

1.

Elevate the rear of the machine so that the track is off the
floor.

2.

Rotate the driven clutch counter-clockwise to move all the
chain slack to the tensioner side.

3.

Lock the parking brake while holding the driven clutch
stationary.

4.

Loosen the adjuster bolt jam nut (A)

5.

Finger tighten the adjuster bolt (B).

6.

Back off the adjuster bolt 1/4 turn out (counterclockwise).

7.

Tighten the jam nut while holding the adjuster bolt.

8.

Release parking brake.

NOTE: It may be necessary to remove the exhaust
pipe and resonator to access the tensioner bolt.

Track Alignment

NOTE:  Track alignment affects track tension.
Misalignment of the track will cause excessive wear
to the track, rail slides, and rail.

1.

Using a track stand or similar device, lift and support the
rear of the snowmobile off the ground.

2.

Inspect the lugs and rods for damage. If any damage is
found, the track should be replaced.

3.

Start the engine. Apply just enough throttle to slowly rotate
the track at least five complete revolutions.

4.

Stop the engine.

5.

Verify the rails are centered within each track window. 

6.

To adjust the track, loosen the rear idler wheel shaft
fasteners. 

7.

If the track runs to the left, loosen the left locknut and
tighten the left adjusting bolt (D). If the track runs to the
right, loosen the right locknut and tighten the right adjusting
bolt. It may be necessary to check this with the engine
rotating the track. ALWAYS SHUT THE MACNINE OFF
before making any adjustments.

8.

After any adjustments are complete, torque the locknuts to
35 ft-lb (48Nm).

9.

Torque both idler shaft bolts to 35 ft-lb (48Nm).

WARNING

Broken track rods can cause a rotating track to come off 
the machine. Never operate or rotate a damaged track 
under power with a broken rod. Serious injury or death 
may occur.

WARNING

When performing the following checks and adjust-
ments, stay clear of all moving parts to avoid personal 
injury. Never make any adjustments with the engine 
running, as serious personal injury can result.

Track Tension

1.

Using a track stand or similar device, lift and support the
rear of the snowmobile off the ground.

2.

Place a 10 lb. (4.54kg) weight at point (A). Point (A) is 16”
(41cm) ahead of the rear idler shaft (E).

3.

Measure the distance (D) between the rail slider and the
track. This measurement should fall with in the
measurement range for the appropriate vehicle.

4.

If adjustment is needed, loosen up the lock nuts (B) on each
side.

5.

Loosen he idler shaft bolts (F).

6.

Turn each adjuster bolt (C) toward the idler wheel
(clockwise) if you need less of a measurement. Tun the
adjuster bolt (C) toward the front of the sled
(counterclockwise) if you need a greater measurement.

When you achieve the correct tension listed below, torque the 
lock nuts (B) and idler shaft bolts on each side to 35 ft-lb 
(48Nm).

Track Lubrication

The slide rails need snow for lubrication and cooling. Excessive
wear indicates insufficient lubrication. A new rail slide can
cause faster heat build-up in limited lubrication, resulting in

excessive wear.

WARNING

Operating with insufficient lubrication between the rail 
slide and track guide clips can cause track failure, loss 
of vehicle control and loss of braking ability, which can 
result in serious injury or death. Avoid operating vehicle 
on ice and other surfaces that have little or no snow 
conditions.
