7. When the track is off of the tension wheel,
remove it from the drive sprocket and road
wheels (Figure 39).
8. Beginning at the drive sprocket, coil the new
track around the sprocket, ensuring that the
lugs on the track fit between the spacers on the
sprocket (Figure 39).
9. Push the track under and between the road
wheels (Figure 39).
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 (Figure 37) 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. Lower the traction unit to the ground.
14. Repeat steps 2 through 13 to replace the other
track.
Replacing the Tracks (TX 425, Model
22307)
When the tracks are badly worn, replace them.
1. Lower the loader arms, stop the engine, and
remove the key.
2. Lift/support the side of the unit to be worked
on so that the track is 3 to 4 inches (7.6 to 10
cm) off of the ground.
3. Remove the locking bolt and nut (Figure 38).
4. Using a 1/2 inch drive socket, release the
drive tension by turning the tensioning screw

on each side of each wheel.
10. Clean the old grease and dirt out of the area
between where the washers were installed and
the bearings inside the wheels, then fill this
area on each side of each wheel with grease.
11. Install the large washers on the wheels over
the grease.
12. Install the inner tension wheel and secure it
with the nut removed previously (Figure 40).
13. Torque the nut to 300 ft-lb (407 N⋅m).
14. Install the new track, ensuring that the lugs in
the track fit between the spacers in the middle
of the drive sprocket (Figure 40).
