around the sprocket, ensuring that the lugs on the track
fit between the spacers on the sprocket (Fig. 37).
9.
Push the track under and between the road wheels
(Fig. 37).
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
fork tube (Fig. 35) is 2-3/4 inches (7 cm).
12. Align the closest notch in the tension screw to the
locking bolt hole and secure the screw with the locking
bolt and nut.
13.
