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 machine in extremely cold weather and 

warm it up. Break machine 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)

• 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 machine in extremely cold weather and 

warm it up. Break machine loose from the snow.

Poor engine performance

• Check for carburetor and choke synchronization, fouled 

plugs, debris in the carburetor(s) and water, ice or dirt 

in the fuel tank or fuel line.

Loading machines onto 

trailers

• Skis may gouge into trailers and prevent the drivetrain 

from spinning properly.  Use enough speed to drive the 

machine completely onto the trailer.  Push and pull it to 

finish loading if necessary.

Clutch malfunction

• Inspect clutch components.  See your dealer.

Slow, easy clutch engage-

ment

• Use fast, aggressive throttle to engage clutch.
