filter (Figure 36).
2. Place the air cleaner assembly onto the air cleaner
base (Figure 34).

nut (Figure 34). Torque the nut to 95 inch-lb (11
N-m).
4. Install the air cleaner cover and secure with the knob
(Figure 34).

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, set the parking brake, stop
the engine, and remove the key.
