TROUBLESHOOTING

Drive Belt Troubleshooting

Belt Wear/Burn Diagnosis

Causes

Solutions

Driving at low RPM

• Drive at higher RPMs. 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/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 performance

• Check for fouled plugs and water, ice or dirt in the fuel 

tank or fuel line.

Loading snowmobiles 
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.
