TROUBLESHOOTING

Drive Belt Wear/Burn

Cause

Solution 

Driving at low RPM

Drive at higher RPM. Gear the machine down. Check belt 
deflection.

Insufficient warm-up

Warm the engine at least five minutes. Take the drive belt off 
the snowmobile in extremely cold weather and warm it up. 
Break snowmobile loose from the snow.

Towing at low RPM

Do not tow in deep snow. Use fast, aggressive throttle to 
engage clutch.

Riding with high 
RPM and slow speed 
(8000 RPM at 10 
MPH/16 km/h)

Lower the gear ratio. Reduce RPM. Avoid riding in high 
ambient temperatures. Check for snow ingestion.

Ice and snow build-
up between track and 
tunnel

Warm the engine at least five minutes. Take the drive belt off 
the snowmobile in extremely cold weather and warm it up. 
Break snowmobile loose from the snow.

Poor engine perfor-
mance

Check for fouled plugs or water, ice, or dirt in the gas tank or 
fuel line.

Loading snowmo-
biles onto trailers

Skis may gouge into trailers and prevent the drivetrain from 
spinning properly. Use enough speed to drive the snowmobile 
completely onto the trailer. Push and pull it to finish loading if 
necessary.

Clutch malfunction

Inspect clutch components. See your dealer.

Slow, easy clutch 
engagement

Use fast, aggressive throttle to engage clutch.

Wrong or missing 
belt

Always use the recommended belt.

Improper break-in

Always break in a new belt and/or clutch by avoiding aggres-
sive or high speed operation during the break-in period.
