Belt Wear / Burn Diagnostics

Table 7-1: Belt Wear / Burn Diagnostics

POSSIBLE CAUSE

SOLUTION

Driving at or about engagement RPM for extended periods of 
time in any type of snow condition.

Drive at higher RPM if possible. Gear the machine down. 
Make sure belt deflection is at 1 1/4” to achieve optimum 
starting ratio.

Cold weather startups

Be patient. Warm up engine at least 5 minutes or until it 
readily responds to throttle input. For the quickest most 
efficient drive away in extreme cold weather, take drive belt 
off machine and bring it in to a warm environment. Break 
skis and track loose from the snow. Engage throttle 
aggressively for short durations for initial cold drive away

Towing another machine at or about engagement RPM

When possible, do not go in deep snow when towing another 
machine. Use fast, effective throttle to engage the clutch. Not 
all machines are intended for pulling heavy loads or other 
machines.

Spinning track while vehicle is stuck (high RPM, low vehicle 
speed, high ambient temp. Example: 8000 RPM, 10mph 
actual vehicle speed and 60 m.p.h. indicated on speedometer.

Lower the gear ratio. Remove windage plates from driven 
clutch. If possible, move to better snow conditions and 
reduce RPM. Avoid riding in very high ambient temperatures

Ice and snow piled up between track and tunnel overnight or 
after stopping for a long period of time (enough to re-freeze 
the snow).

Break loose snow and ice under tunnel. Allow longer than 
normal warm-up. Allow belt to warm sufficiently and 
increase grip ability on clutch sheaves. Use fast, effective 
throttle when engaging clutch.

Poor running engine (Bog, Miss, Backfire, etc.)

Maintain good state of tune including throttle and choke 
synchronization. Check for fouled spark plug(s). Check for 
foreign material in carburetors. Make sure no water or ice is 
present in the fuel tank, lines, or carburetors.

Loading machine on trailer

Use caution when loading machine. Carbide skags may 
gouge into trailer and prevent drive train from spinning 
freely. Use enough speed to drive completely onto trailer. If 
machine cannot be driven completely onto trailer, it may need 
to be pulled or pushed to avoid belt wear / burning.

Clutch malfunction

Check for correct clutch components, or damage on the 
clutch

Slow, easy belt engagement - easing on the throttle

Use fast, effective throttle to engage the clutch.

Drive Belt Removal - Team Driven Clutch

NOTE:  Turn the key to the “OFF” position and allow
the engine to come to a complete stop.

1.

Verify the driven clutch is not in reverse. Open the clutch
guard.

2.

Insert the L wrench, PN 2874857 (A), into the threaded hole
(B) located on the driven clutch, and turn it clockwise until
the clutch sheaves are in the open position (C).

3.

Remove the drive belt.

Drive Belt Installation - Team Driven Clutch

1.

With the L wrench inserted into the threaded into hole and
the sheaves in the open position, install the drive belt.

NOTE:  Install belt so that the numbers can be read
correctly on the left side of the machine or in the
direction in which the belt was originally installed.

2.

Remove the wrench. “Wiggle” the belt to remove slack
while removing the wrench.

3.

Close the clutch guard.

Adjusting Belt Deflection - Team Driven 

Clutch

1.

Loosen the jam nut.

2.

Using an 1/8

 Allen head wrench, turn the stud counter-

clockwise to decrease belt deflection and clockwise to
increase belt deflection.

3.

When the proper belt deflection is achieved torque the lock
nut to 90 - 110 in-lb. (10 - 12 Nm).

NOTE: When using a MBL drive belt, the belt
deflection should be set so that .9

 to .10

″ 

of the

outer cogs are outside of the driven sheaves.

CAUTION

Damage to the driven clutch or L wrench will occur when 

attempting to open the driven clutch when the driven 

clutch is in the reverse position.

PVT SYSTEM ADJUSTMENTS

Clutch Alignment / Offset

The engine is mounted in the bulkhead so the drive and driven
clutches self-align under high torque loads.

Offset is controlled by the number of washers installed on the
jackshaft behind the driven clutch.

1.

Remove drive belt.

2.

Install the correct alignment tool depending on the type of
driven clutch installed on the snowmobile.

NOTE:  A standard alignment tool will not work with
a Team LW driven clutch. Likewise, a LW alignment
tool will not work with a standard Team driven
clutch. A Team LW driven clutch can be identified as
having 24 cooling fins.

3.

The optimum setup is when the front and rear of the tool
touch the driven clutch. No gap should be present in the
front, and the rear clearance should not exceed .060"
(3mm).

NOTE: If the front of the alignment bar does not
touch the driven sheave, the maximum clearance
cannot exceed .025

.

Offset Adjustment

1.

Determine direction driven clutch needs to be adjusted.

2.

Remove driven clutch retaining bolt, and remove driven
clutch.

3.

Add or remove washers from the jackshaft between the
driven clutch and jackshaft bearing to achieve proper offset.

4.

After adjusting offset, add or remove shim washers from
the retaining bolt to provide a +/- 0.030” (.75mm) of float
on the jackshaft.

CAUTION

Always verify the driven clutch floats on the jackshaft 

after securing the fastener. The jackshaft bearing will fail 
due to side-loading if the driven clutch is not allowed to 

float.

DRIVE CLUTCH

Identification

Every clutch will have the last three digits of the clutch part
number etched on to the cover (A). The “X" (B) marking is an
index mark where the clutch cover (C), clutch spider (D) and the
stationary sheave (E) should line up when the clutch is
assembled.

Drive Clutch Removal 

NOTE:  All clutch tools can be found at the 
beginning of this chapter. 

1.

Remove the belt.

2.

Place the clutch holding tool (PN 9314177-A) on the drive
clutch.

3.

Remove the drive clutch retaining bolt. Note the placement
and number of washers on retaining bolt.

4.

Insert the correct clutch puller into the retaining bolt hole.

5.

Tighten the puller into the clutch. If the clutch does not
come off, strike the clutch puller head with a hammer. If
the clutch does not “pop” off, continue to tighten the clutch

puller, and repeat this step.
