Belt Wear / Burn Diagnostics
POSSIBLE CAUSE SOLUTION
Driving at or about engagement RPM for extended
pe
riods of time in any type of snow condition.
Drive at higher RPM if possible. Gear the machine
down. Ma
ke sure belt deflection is at 1 1/4” to achieve
optimum starting ratio.
Cold weather startups
Be patient. Warm up engine at le
ast 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
ano
ther 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
ve
hicle speed, high ambient temp. Example: 8000
RPM, 10mph actual vehicle speed and 60 MPH
indicated on speedometer.
Lower the gear ratio. Remove windage plates from
d
riven 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
over
night or after stopping for a long period of time
(enough to re-freeze the snow).
Break loose snow and ice under tunnel. Allow longer
th
an 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
synchr
onization. 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
gou
ge 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
cl
utch
Slow, easy belt engagement - easing on the throttle Use fast, effective throttle to engage the clutch.
