OF the throwout collar and thrust bear
ings. In many trucks 1t Is rather o
nuisance to attend to this job as the
\ floor boards must be lifted to give ac-
cess to the throwout collar. Many
trucks now are being provided with a
more convenient method of lubricatine
this part, which is well, because driv-
ers are likely to slight difficult Jobs
In the case Of disc clutches running in
oil the utmost care must be used to
provide correct lubricant. which is us

kerosene. Tho quality of this mixture
Is generally altered to give thinner
consistency for winter operation.
And the hard working, never com
planning universals. Do they always
get the care they need and deserve
They run at engine speed, and they
must have constant fabrication IL they
are to continue functioning properly.
Grease or graphite is commonly used
because Oil leaks out of the housing.
In summer even grease gets thin and
leaks out of the universals These
parts should be repacked every time
the crank case is drained and refilled.
ENGINE SPEED is BASIS
And that brings us to what may we'll
be made a major lubricating rule in
truck operation; to use engine speed as
the basis for determining periods at
which fabrication must be given, Parts
that operate at engine speed should re-
ceive lubricant whenever the engine
does, as with the universals noted
above. II the engine oil is changed
once every 1000 miles, then change
parts that run at half engine speed
every 1000 miles.
Gear sets, axles and jack shafts
should all have the same careful at
tention in the way of fabrication. Too
many truck drivers seem to make it
a rule to let gears and bearings go
until they make audible protest The
trouble with this method is that when
the protest becomes audible the cause
has gone so far that extensive repairs
are needed. And cost per mile must
always include that little item of re-
pairs. :
The truck owner should make 1t a
rule never to employ grease in gear
unite. Grease against the side of the
gear housing and the gears run prac-
tically bare. The only proper Iubri-
cant for gears is oil, either gear oil

WHERE OIL MEANS SAFETY
Side chains are difficult to keep lu-
bricated because they run exposed.
These chains should never be lubri-
Gated without first being washed off
in kerosene. Internal gear axles need
careful watching. Sometimes the dust
cover leaks and allows grit to get into
the gear teeth, causing rapid wear and
noisy operation.
The steering system of the motor
truck should have daily attention The
steering knuckle pin, the drag link
joints and the rod must be well lubri-
Gated in the interests of safety first.
Grease is the usual lubricant or the
ball joints of the steering system, and
1t should be replenished every day,
while the gear case at the bottom of
the steering post will get along with a
monthly overhauling.
In addition to the major parts of the
