Figure 16-11 16-008
2. Lay a straightedge along the top of the track be-
tween the sprocket and the front idler wheel.
3. Using a rope or wire, put 50 pounds of down
force on the track at the midpoint of the straight-
edge.
Figure 16-12 16-009
4. Using a ruler, measure the distance between the
straightedge and track. The track should not de-
flect more than 0.75 inch between the top of the
track and the straightedge.
5. If the track deflects more than 0.75 inch, tighten
the track.
