Belt Wear / Burn Diagnostics

POSSIBLE CAUSE
Driving at or about engagement RPM for extended
periods of time in any type of snow condition.
Cold weather startups
Towing another machine at or about engagement RPM
Spinning track while vehicle is stuck (high RPM, low
vehicle speed, high ambient temp. Example: 8000
RPM, 10mph actual vehicle speed and 60 MPH
indicated on speedometer.
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).
Poor running engine (Bog, Miss, Backfire, etc.)
Loading machine on trailer
Clutch malfunction
Slow, easy belt engagement - easing on the throttle
6.12
SOLUTION
Drive at higher RPM if possible. Gear the machine
down. Make sure belt deflection is at 1 1/4" to achieve
optimum starting ratio.
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
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.
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
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.
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.
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.
Check for correct clutch components, or damage on the
clutch
Use fast, effective throttle to engage the clutch.
