until the upper span of the drive chain is tight.
6. Adjust the chain tensioning bolt until the distance
between the bottom of the chain guard and the lower
chain span is within 1–1/2 to 2–1/2 inches (3.8 to 6.35
cm) (Fig. 22).
7. Position the axle retaining bracket tight against the
axle and the frame, then tighten the jam nut on the bolt
to secure it in place (Fig. 23) and torque the nut to 30
ft-lbs (40.7 N⋅m).
8. Tighten the nuts securing the axle retaining bracket

Changing the Oil
1. Start the engine and let it run for five minutes. This
warms the oil so it drains better.
2. Park the traction unit so that the drain side is slightly
lower than the opposite side to ensure that the oil
drains completely.
3. Lower the loader arms, chock the wheels, stop the
engine, and remove the key.
Components will be hot if the traction unit has
been running. If you touch hot components you
may be burned.
Allow the traction unit to cool before performing
maintenance or touching components.
Caution
4. Place one end of a hose on the drain valve and the
other end in a pan.
5. Open the drain valve by turning it counterclockwise,
pulling out as you turn it
(Fig. 24).
6. When the oil has drained completely, close the drain
valve and remove the hose.
