TROUBLESHOOTING

Suspension Troubleshooting

Problem

Solution (perform only one change at a time)

Rear suspension 
bottoms too easily

• Verify sag dimension (see page 90). Adjust torsion spring 

blocks or install optional torsion springs to achieve correct 
sag dimensions.

Rear suspension 
rides too stiff

• Check for binding suspension components and grease all 

pivot points.

• Verify sag dimension (see page 90). Adjust torsion spring 

blocks or install optional torsion springs to achieve correct 
sag dimensions.

• Decrease shock compression damping (see page 35).

Too much weight 
transfer when 
climbing

• Verify sag dimension (see page 90). Adjust torsion spring 

blocks or install optional torsion springs to achieve correct 
sag dimensions.

• Adjust suspension coupler (see page 35).

Too little weight 
transfer when 
climbing

• Verify sag dimension (see page 90). Adjust torsion spring 

blocks or install optional torsion springs to achieve correct 
sag dimensions.

• Adjust suspension coupler (see page 35).

Front end pushes

• Check for worn skags
• Check for binding front suspension shafts and steering com-

ponents, grease all pivot points (elevate front of machine).

• Verify sag dimension (see page 90). Adjust torsion spring 

blocks or install optional torsion springs to achieve correct 
sag dimensions.

• Increase IFS preload (see page 33).

Steering is heavy

• Check skags and skis for damage.
• Check for binding front suspension shafts and steering com-

ponents, grease all pivot points (elevate front of machine).

• Verify sag dimension (see page 90). Adjust torsion spring 

blocks or install optional torsion springs to achieve correct 
sag dimensions.

• Decrease IFS preload (see page 33).

Snowmobile darts 
from side to side

• Ensure skis are properly aligned (see page 93).
• Check for binding front suspension shafts and steering com-

ponents, grease all pivot points (elevate front of machine).

• Ensure skags are straight on skis.

TROUBLESHOOTING

Belt Wear/Burn 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 high gear. 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. Remove windage plates from the 
clutch. Reduce RPM. Avoid riding in high ambient 
temperatures.

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 carb and choke synchronization, fouled plugs, 
debris in the carbs, and water, ice or dirt in the gas tank or 
fuel line.

Loading snowmobiles 
onto trailers

Skis may gouge into trailers and prevent the drive train 
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.
