LUBRICATION
0-1 1
FRONT WHEEL BEARINGS
When an inspection of the wheel bearings indicates
the lubricant is low in quantity, or contaminated with
dirt or water to produce a milky appearance, the bear-
ings should be cleaned, inspected and relubricated if
serviceable.
CAUTION: To
avoid possible contamination of the
lubricant by mixing lubricants that are not compat-
ible, do not add lubricant to the bearings.
Thoroughly clean the old lubricant from the bear-
ings and hubs. Repack the bearings and hubs with Au-
tomotive Multi-Purpose Grease, NLGI grade 2. When
repacking hubs, (Fig. 21) make sure all surfaces of the
hub and outer grease cup interiors are covered with
lubricant to minimize condensation and lubricant
travel out of the bearing.
DO
NOT OVER FILL.
Adjust the bearings as follows:
(1) Tighten wheel bearing adjusting nut (Fig. 22) to
70
inch-pounds on AV-1, AV-2 models and 90 inch-
pounds on AR-1, AR-2, AP-1, AP-2 models, while ro-
tating the wheel.
(2) Position nut lock on adjusting nut so one pair
of cotter pin slots align with the hole in the spindle
(Fig. 22).
(3) Back off the adjusting nut and nut lock to the
next slot and install the cotter pin.
(4)
Install wheels, tighten wheel nuts to 55 foot-
pounds on AV-1, AV-2 models and 65 foot-pounds on
AR-1, AR-2, AP-1, AP-2 models. Install the wheel cov-
ers.
TIRES
Tires, including the spare, should be rotated accord-
ing to tire rotation diagram (Fig. 23), to provide uni-
form wear, long
tire
life, and to retain comfortable
riding qualities.
Tires should be examined for unusual wear pat-
terns, foreign material and proper inflation pressures.

Wheel Bearing Adjustment
Unusual wear conditions may reflect unusual driving
habits or indicate that mechanical corrections may be
necessary.
Refer to Lubrication and Maintenance Charts (Figs.
1 and 2), for recommended inflation pressures.
COOLING SYSTEM
Inspect the coolant level every two months. The
cooling system should be drained, flushed and re-
filled with the proper coolant in the spring and in the
fall. When necessary to remove accumulations of
rust
and other deposits, maximum cleanliness can be
re-
stored by using a reliable Cooling System Cleaner,
according
to
the directions on the container.
Drain V-8 engine cooling systems by removing both
drain plugs in the sides of the cylinder block and open
