FRONT WHEEL BEARINGS
%,
%,
1 and 1% Ton. Front wheels are equipped with ball
bearings and should be packed with a high-melting point front
wheel bearing lubricant.
L.C.F. 2 and 2% Ton. Front wheels are equipped with tapered
roller bearings and should be packed with a soft smooth
lubricant.
CAUTION: "Long fibre" or "Viscous" type of lubricants should
not be used.
Due to the weight of the tire and wheel assembly it is recom-
mended that they be removed from hub before lubricating bear-
ings to prevent damage to oil seal. Then remove the front wheel
hub to lubricate the bearings. The bearings should be thoroughly
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 49).
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 "Ch'C1ssis 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
8%
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 should be lubricated
with lubricant recommended under "Chassis Lubrication."
