Ski Skags

WARNING
Worn skis and/or skags will adversely affect handling. Loss of vehicle control may result, causing serious injury or death. Your dealer's studding chart can provide the recommended skags. If you install longer or more aggressive carbide skags than the original equipment, it may also be necessary to add track studs to maintain proper vehicle control while turning on hard-packed snow or ice.
Check skags before each use of the snowmobile to ensure positive steering characteristics. Skags must be replaced when worn to half their original diameter.
TIP
Carbide skags must be replaced if any abnormal wear or chipping is found.

Skag Replacement

  1. Raise and support the front of the snowmobile so the skis are approximately 6 inches (15.2 cm) from the ground.
  2. Remove the attaching nuts and pry the skag downward.
  3. Remove the front end of the skag.
  4. Remove the rear end of the skag.
  5. Reverse the steps to install a skag.
