Track Tension

Track tension is directly related to the
overall performance of the snowmobile.
If the track is too loose, it may slap
SNO-336
against the tunnel causing wear or it may
"ratchet" on the track drive sprockets. If
extremely loose, the idler wheels may
climb over the track lugs forcing the
track against the tunnel causing the track
clean the
to "lock." Yamaha recommends that the
track tension be checked daily during the
first 500 km (300 miles) of operation and
once a week thereafter and adjusted
according to need. The track will stretch
and take a "set" during break-in. Track
deflection must be maintained within the
recommended range.
Track tension must be properly
maintained. Personal injury could
result if a track is allowed to
become excessively loose.
