before performing the hot check. Run the engine
between 1,000 and 1,200 RPM for approximately
one minute to purge air from the system. With
the engine idling and the parking brake applied,
shift transmission from forward (D) to reverse
(R) and back into neutral (N) to fill clutch cavities
with oil. Remove and clean dipstick, then check
oil level. If the oil level is on or under the lower
HOT RUN line, add just enough oil to bring up
the level to the middle of the HOT RUN band

DRIVE AXLE WHEEL BEARING OIL LEVEL
Drive axle wheel bearings are lubricated by the
differential oil. Maintain differential oil at correct
level to ensure adequate lubrication of drive axle
wheel bearings at all times.
FRONT AND TAG AXLE WHEEL HUBS
The unitized hub bearings used on the NDS range
of axles, are non-serviceable items. Bearings are
pre-adjusted, lubricated and have seals fitted as
part of the manufacturing process. The bearings
are greased for life and there is no need or facility
for re-lubrication.
COOLANT FLUID LEVEL
Check the coolant level when the engine is cold
(room or ambient temperature).

If the coolant level has reached the bottom
of the sight glass, add coolant up to the
middle of the sight glass.
Fill the tank as required with the same 50/50
water-antifreeze mixture already in the cooling
system.
Do not mix two different types of
coolant. Refer to the Maintenance Manual for
proper coolant type specifications or see the
label affixed near the coolant surge tank on the
vehicle.
