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.
