The Importance of proper adjustment of
] side-drive chains of commercial vehicles
seems to be commonly lost sight of, or,
PERHAPS. not fully understood by even
those connected with the truck industry.
+ Mess proper care is exercised in this
! regard. there will be a greatly increased
| spTockets. and decreased efficiency i'm the
work. of the truck If the vehicle is of
| proper. design. the sprocketS on the out
board ends of the jack. shafts will be in
-,
and should the contrary be found, the
| trouble lies in "a bent axle or jack shaft,
improperly fitted sprockets. or possibly in
the design itself. Whatever the cause,
however, the matteE should be corrected
at. once. Connecting the rear axle of the
truck with the jack shafts will be found
a rod or other substantial member fitted
with an adjustable nut or turnbuckle: this
| member Is variously known as a dis
lance rod or radius rod" sometimes
! improperly referred to as a ''tortion rod
The purpose Of this distance rod is to
| maintain a certain fixed distance between
the centerS of the jack shaft and the rear
axle regardless of spring set, due to load
or road shock.
Having found that all four sprockets
line mp properly, the next thing neces-
sary is to arrange to have the side driv-
ing chains neither too tight nor too
loose. but just slack enough to allow
of the very slightest sag. This adjust
ment is arranged for by the adjustment
nut or turnbuckle on the radius rods
but in making this adjustment it is i'm
perative that absolutely the same dis
tance between the jack shaft and axle
center exist on both sides Owing to the
fact that both driving chains will not
always wear alike, it may be necessary
to either add or take out one or more
links in one of the chains when making
adjustments or replacements. Having
made the proper adjustment, 1t is well
to. see that the adjustment nut or turn
vent any loosening through vibration
or road shock. There are a number of
vehicles with distance rods so improper
1y designed as to permit Of change i'm
centers between jack shaft and rear
axle, due to set of springs through load
or road shock, or which buckle slightly
when power is suddenly applied Under
these circumstances chain adjustment
should be made for the greatest distance
possible, as otherwise there will be great
danger of breaking one or both chains
or bending the Jack shafts when bad
pavement or road distractions are en-
countered

First i'm Importance to the world of in
dustry has been the progress achieved by
the automobile business wagon during the
past year. At the beginning Of the pres
ent year every line of business in the
land that requires the transportation of
hicle. During the past year the use of
freight automobiles has increased re-
markab1y. and operation under varied
conditions has demonstrated betterment
of service and economy resulting from
their use.
Among the newer fields into which the
automobile truck has been introduced
with success is in the service Of land and
development companies. The trucks are
fitted with seating accommodations for
