Rear Wheel Bearings; Chassis - Chevrolet Light Operator's Manual

cleaned before repacking with lubricant. Do not pack the hub
between the inner and outer bearing assemblies, or the hub
cap, as this excessive lubrication results in the lubricant work-
ing out into the brake drum and linings.
In mounting the front hubs, great care must be taken not
to
damage seals and to properly adjust bearings, (see page 46).
REAR WHEEL BEARINGS
The rear wheel bearings receive their lubrication from the
rear axle. When installing bearings which have been cleaned,
repack with a smooth type grease.
CHASSIS
For chassis lubrication, consult the lubrication chart, which
shows the points to be lubricated and how often the lubricant
should be applied.
The term "Chassis Lubricant" as used in this manual, de-
scribes a semi-fluid lubricant designed for application by
commercial pressure gun equipment. It is composed of mineral
oil (usually 300 to 500 second Saybolt Universal viscosity at
100 0 F.) combined with approximately 870 soap, or soaps,
which are insoluble in water.
Spring Shackles and Spring Bolts
The spring shackles and spring bolts are equipped with
pressure gun lubrication fittings, and
~hould
be lubricated
with lubricant recommended under "Chassis Lubrication."
Brake and Clutch Pedals
The brake and clutch pedals on
t~e
Cab-Over-Engine truck
models are equipped with pressure gun lubrication fittings.
On the other truck models, only the brake pedal is equipped
with a pressure gun lubrication fitting; the lubricant so ap-
plied lubricates both the brake pedal and the clutch pedal.
Use chassis lubricant at these points.
Brake and Clutch Idler Lever
(%
and 1 ton Fonyard Control)
The brake idler lever on the above models is equipped with
a pressure gun lubrication fitting. Lubricate with chassis lubri-
cant every 1,000 miles.
