5. Using a 1/2-inch drive ratchet, turn the
tensioning screw counterclockwise until the
distance between the tension nut and the back
of the tension tube (
Figure 46 ) is 7 cm (2-3/4
inches).
6. Align the closest notch in the tension screw to
the locking bolt hole and secure the screw with
the locking bolt and nut (
Figure 47 ).
7. Lower the traction unit to the ground.
Replacing the Tracks
Replacing Narrow-Width Tracks
When the tracks are badly worn, replace them.
Note:
You have narrow-width tracks if the front
tension wheels are mounted inside a fork on the end
of the tension tube (
Figure 48 ).
1. Park the machine on a level surface, engage the
parking brake, and lower the loader arms.
2. Shut off the engine and remove the key.
3. Lift/support the side of the unit to be worked on
so that the track is 8 to 10 cm (3 to 4 inches)
off the ground.
4. Remove the locking bolt and nut ( Figure 47 ).
5. Using a 1/2-inch drive ratchet, release the
drive tension by turning the tensioning screw
clockwise (
Figure 47 and Figure 48 ).
