Track Break-In

It is very important to inspect and adjust track tension after every ride for the first 150 mi (240 km) of use to ensure the proper tension during the break-in period. Aggressive riders in certain snow conditions may need to adjust track tension as early as 20 mi (32 km). After the break-in period track tension should be inspected every 150 mi (240 km).

IMPORTANT
Track tension must be kept at specification – neither too loose nor too tight. Overly loose track tension is inefficient and overly tight tension causes premature wear or drive train system failures.
NOTICE
Ratcheting occurs when the drive shaft drivers slip on the track. A ratcheting event typically produces extreme vibration and is often experienced when the track is subjected to heavy loads.

Early wear can be caused by two conditions – improper track tension and/or sustained trail riding at high speeds without scratchers. Neither condition results from a defect in the track, and wear caused by either or both of these conditions is not covered by warranty.

Loose tracks reduce drive system efficiency because:

  • Track tension constantly varies on snowmobiles as the rear suspension extends and compresses.

  • Loose track tension increases the chance for the drive shaft to ratchet in high load driving modes. Track ratcheting may damage the track and drive nubs.

  • Loose track tension decreases rail slider life and can cause uneven slider wear.

  • The slack in a loose track bows out in front of the rail tips. This bowing effect significantly reduces drive system efficiency, creates drag, and changes the approach angle of the rear suspension, which decreases the snowmobile's ability to get on top of the deep snow.
