Reinstall the nuts and torque to 10 ft-lbs maximum.
6. Remove the reservoir breather, wash the breather in
fuel oil and dry it with compressed air. Fill the reservoir up to
the full mark on the sight gauge (see Figure 5A-4) with the
type of fluid specified in Section III.
7. Start the engine and allow it to idle for a few minutes.
With the clutch disengaged, check the oil level. If neces-
sary, add oil to bring the level up to the full mark. Install the
filler-breather cap.
LUBRICATE CLUTCH BEARINGS
See Figure 5E-6 and lubricate with the type of grease speci-
fied in Section III. Two "shots" of grease from a grease gun
should be enough.
Figure 5E-5. Torque Converter Reservoir
To change the fluid and filter, proceed as follows:
1. Warm the oil in the system to its normal operating
temperature. Position the machine so that the drain plug
can be reached and then shut down the engine.
The oil in the reservoir is hot, therefore, take
precautions when removing the reservoir drain
plug to prevent oil burns.
