YETI SNOWMX USER MANUAL
TRACK TENSION
CAUTION: The two rear wheel assembly axle nuts
(1) must be loosened before adjusting Track
tension. See Figure 46.
Figure 46
• Rotate the right and left rear wheel axle
adjusting bolts (
2
) an equal number of turns,
clockwise or counterclockwise, to set the Track
to the recommended tension. See Figure 47.
Figure 47
CAUTION: Use a ruler to verify how long the
adjusting bolts are engaged in the axle. A
misaligned rear axle can cause premature wear of
suspension components.
• The table below shows the force applied and the
deflection which must/ occur when track tension
is correctly set. Refer also to Figure 48.
BASIC TUNING
• A higher rubber track tension reduces drive
“ratcheting”.
NOTE: Track tension set too high could cause
premature wear on system components.
• A lower rubber track tension provides better
traction, a smoother ride and better fuel
economy.
• Check Track tension using as reference points
the rubber bumpers located at mid-point
between the two lower shock absorber mount
shafts. See Figure 48.
Figure 48
• Tighten the two rear wheel axle nuts (
1
) back to
55 Nm (38 lb-ft) of torque. See Figure 46.
NOTE: The track tension testing tool shown below in
Figure 49 can be purchased through an
authorized YETI dealer. The part number is
2000-00-3125.
