Suspension Troubleshooting
Problem Solution (perform only one change at a time)
Rear suspension
bottoms too easily
- Verify sag dimension (see set-up decal).
Adjust torsion spring blocks or install optional torsion
springs to achieve correct sag dimensions.
- Increase shock compression damping (see page 49).
Rear suspension
rides too stiff
- Check for binding suspension components and grease all
pivot points.
- Verify sag dimension (see set-up decal).
Adjust torsion spring blocks or install optional torsion
springs to achieve correct sag dimensions.
- Decrease shock compression damping (see page 49).
Too much weight
transfer when
climbing
- Verify sag dimension (see set-up decal).
Adjust torsion spring blocks or install optional torsion
springs to achieve correct sag dimensions.
- Move limiter strap on front torque arm to high position
(see set-up decal).
Too little weight
transfer when
climbing
- Verify sag dimension (see set-up decal). Adjust
torsion spring blocks or install optional torsion
springs to achieve correct sag dimensions.
- Move limiter strap on front torque arm to low position
(see set-up decal).
Front end pushes - Check for worn skags
- Check for binding front suspension shafts and steering
components, grease all pivot points (elevate front of machine).
- Verify sag dimension (see set-up decal). Adjust
torsion spring blocks or install optional torsion
springs to achieve correct sag dimensions.
- Increase IFS preload (premium only) (see page 44).
- Move limiter strap on front torque arm to high position
(see set-up decal).
Steering is heavy - Check skags and skis for damage.
- Check for binding front suspension shafts and steering
components, grease all pivot points (elevate front of machine).
- Verify sag dimension (see set-up decal).
Adjust torsion spring blocks or install optional torsion
springs to achieve correct sag dimensions.
- Decrease IFS preload (premium only) (see page 44).
Machine darts from
side to side
- Ensure skis are properly aligned (see page 103).
- Check for binding front suspension shafts and steering
components, grease all pivot points (elevate front of machine).
- Ensure skags are straight on skis.
