7. When the track is off of the tension wheel, remove it
from the drive sprocket and road wheels (Figure 42).
8. Beginning at the drive sprocket, coil the new track
around the sprocket, ensuring that the lugs on
the track fit between the cogs on the sprocket
(Figure 42).
9. Push the track under and between the road wheels
(Figure 42).
10. Starting at the bottom of the tension wheel, install
the track around the wheel by rotating the track
rearward while pushing the lugs into the wheel.
11. Turn the tensioning screw counter-clockwise until
the distance between the tension nut and the back of
the tension tube (Figure 40) is 2-3/4 inches (7 cm).
12. Align the closest notch in the tension screw to the
