| 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. Put the transmission in neutral to warm belt. In extreme cold weather, take the drive belt off the snowmobile 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. Your dealer can perform this service. |
| Slow, easy clutch engagement | Use fast, aggressive throttle to engage clutch. |
