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 / P2 (SPA)

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

P2 (SPA) = Single Point Adjuster

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

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).

Remove the drive belt.

Drive Belt Installation - Team / P2 (SPA)

With the L wrench inserted into the threaded hole (B)
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.

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

Close the clutch guard.

Adjusting Belt Deflection - Team / P2 (SPA)

Loosen the jam nut.

Using an 1/8



Allen head wrench, turn the stud

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

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.

Drive Belt Removal - P2 (Cam Adjuster)

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

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

Insert the L wrench, PN 2874857, into one of the
threaded holes located on the driven clutch. Turn it
clockwise until the clutch sheaves are in the open
position.

Remove the drive belt.

Drive Belt Installation - P2 (Cam Adjuster)

With the L wrench inserted into one of the threaded
holes 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.

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

Close the clutch guard.

Adjusting Belt Deflection - P2 (Cam Adjuster)

Loosen, but do not remove the three screws on the
deflection cam.

Rotate (clockwise) the deflection cam towards #1 in
small increments to decrease belt deflection.

Rotate (counterclockwise) the deflection cam towards
#5 in small increments to increase belt deflection.

Do not rotate cam past #1 or #5.

When the proper belt deflection is achieved torque the
lock nut to 12 ft. lbs. (16 Nm).

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.

Drive Belt Removal - Widetrak Driven

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

Open the clutch guard.

Set the parking brake. Firmly grasp the belt and pull
upwards towards the hood.

Roll the belt out of the driven clutch and remove the
drive belt.

Drive Belt Installation - Widetrak Driven

Install the drive belt around the drive clutch.

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.

Wrap the belt around the top of the driven clutch (A),
then pull it around the rear (B).

Firmly push on the moveable sheave while pulling the
belt down into the sheaves from the rear.

Close the clutch guard.
