Slider Wear
Measure slider thickness at
several points along the
rail. Have your dealer
replace the slider when it’s
worn down to the top of
the wear groove (A). Do
not operate the snowmobile if
slider thickness measures less
than 7/16″ (1.1 cm).
n Pre-Ride Suspension Inspection
Loose nuts and bolts can reduce your snowmobile’s reliability and
cause needless repairs and down time. Before beginning any
snowmobile trip, a visual inspection will uncover potential problems.
Check the following items on a weekly basis or before any long trip:
n
Check rear idler wheel bolts for tightness.
n
Check rear idler adjusting bolt locknuts for tightness. See page 89
for torque specs.
n
Check front torque arm limiter strap condition.
n
Check slider condition - have your dealer replace when worn to
minimum thickness.
n
Check track tension (beginning on page 88).
n
Lubricate/grease all suspension components (see page 63).
n
Check ski runner/skag condition.
