End Connectors
Always replace end connectors
when they reach their wear limit
of less than
3
/
16
inch. Bad end
connectors don’t Ft well on the
sprocket teeth. That results in
wear that can ruin even a new
sprocket in short order.
Sprocket Reversal
Speaking of sprockets, you should plan to
reverse them annually. That evens out wear on
the sprocket teeth.
However, if the sprocket is worn to the back
edge of the wear mark before the year is up, go
ahead and reverse the assembly. If the marks
are reached on both sides, replace the sprocket.
Track Tension
Track tension is important when it comes to track component wear. Track that is
too tight wears out end connectors and cups sprockets. Track that is too loose may
result in thrown track.
±ollow the instructions in your -10 TM to the letter. You’ll Fnd them starting on
Page 3-21 of TM 9-2350-256-10 (Mar 98) and in WP 108 and WP 109 of TM 9-
2350-292-10 (Nov 05).
Most important of all, make sure you drive the vehicle back and forth a few
vehicle lengths over hard, level ground. Then
coast
to a stop. Using the brake to
stop will throw off the tension adjustment and lead to sprocket cupping.
Center Guides
Measure the thickness of the
center guides one inch down from
the tip. Replace any center guide
that is less than
5
/
8
inch thick at
that point.
Pad Height
Replace the track shoe when its pad is less
than
1
/
2
inch in height.
