The International Harvester COM
pany ut the present time is operating
two motor truck plants, located at
Akron aEdsSpringtield, Ohio. respec-
lively. whilessa third plant for the pro-
dustion III International Motor Trucks
is NOW Under construction at Fort
Wayne. Indiana.
In The .Akron pant the heavy-duty
international Motor Trucks are
al. al, 41,.61, 1O1, with capacities
ranging from 1000 to 10000 lbs.
These trucks are built complete at
Akron. The engine, clutch, trans
mission, d~ifferential, axles, wheels,
steering gear, and in fact all the
working parts Of these trucks are de-
signed by International engineers nj
manufactured by International work
men in the Harvester company's own
plants.
As an example Of how thoroughly
this work is done and how well
equipped the Akron plant Is to turn
out a truck of the very highest grade,
take the production Of an Internation-
alSinternal gear final drive.
Heat-treating, which is one of the
fundamental operations in building a
perfect axle, has been developed to a
very high point at the Akron Works.
The complete and well equipped
heat-treating plant is unexceAed by
tho equipment used in any other
motor truck establishment. This
equipment makes it possible to pro-
duce the highest grade product at a
reasonable price. The weight carry
ing members OF the International rear
axle Is a solid one piece drop-forging.
ITO TURF out such an axle economically
a steam hammer is used which cost
$4,000 to install. This big hammer
is making axles without flaws in them
-axles that are proof against the vi
bration n pounding of steady serv-
ice ver rough pavements and roads
and proof against the steady hauling
of capacity loads.
All other machinery n equipment
esBeS-in use at the Akron Works are
the most up to date and efficient that
the Harvester company's great re-
sources and nearly a century OF
manufacturing experience can pro-
vide.
High Quality Assured.
A rigid inspection system is main
tanned SO that every truck will meas
ure up to the highest standard OF
quality upon which the Harvester
Company has established its reputa-
ton.
International inspection begins
with the materials. Samples are tax

As soon as the material starts

inspectors keep tab Of all machines
and watch all parts to see that they
come through accurately.
When parts have gone through tn,
forge or machine shop they are read!
to be carbonized, case-hardened, o.
heat-treated. When they come. from
the heat-treating department they ar,

the proper amount of strength ha.
been added by the treatment of the
steel that was already strong anc

Certain parts on every motor truck
such as the front and real axles, are
subject to continuous strains while il
use. We adj know that a piece O.
