Glad I bought a real truck” 
“ ’Spose they’ll get that stretch 
of highway fixed some time. Glad 
I had sense enough to buy a real 
truck. She’s simply eaten up this 
blamed detour day after day in good 
weather—guess no storm is going to 
feaze her now!” 
Nowhere is a truck subjected to 
more searching tests of stamina and 
reliability than in the day-in, day- 
out run to market over all sorts of 
road in all sorts of weather—especially 
when the trip includes a detour that 
takes big extra toll in the shape of 
unusual road shocks and strains. 
Has it ever occurred to you how 
much of your truck’s success in 
standing the gaff is due to the 
builder’s wisdom in making the 
foundation of truck staunchness and 
road-ability the use of major units 
that have proved their worth through 
years of the searching tests of actual 
daily work? 
Take axles, for instance. The most 
important unit of all, for the axles 
not only have to carry the load but 
also have to meet every road shock, 
every strain and end thrust of skid¬ 
ding, and of rounding curves. And 
the rear axle particularly, which not 
only carries more than half the load, 
but also has the strenuous task of 
transmitting the power of the engine, 
stepping it down to the wheels, and 
besides has to meet the sudden 
strains of braking. 
If the maker of your truck is one 
of the 60 progressive builders who 
use Timken Axles, you have as the 
final drive and support of the bigger 
part of your load a Timken Worm 
Drive Rear Axle. With its few sim¬ 
ple, sturdy parts—with its one re¬ 
duction worm and gear, whose strong, 
specially formed teeth are always 
held in perfect mesh—with its posi¬ 
tive lubrication of all moving parts, 
you have such a powerful, sure- 
running, trouble-free drive that it is 
bolted up inside the dirt-proof hous¬ 
ing and left there. All the attention 
it needs is occasional lubrication. 
In many a case Timken worm 
gears have run 100,000 miles or more, 
and when examined have been found 
. in perfect condition and ready for 
another hundred thousand. In fact, 
more than nine years constant use 
has not been enough to find their 
mileage limit. Often, even when every 
other part of a truck is “on its last 
legs,” the Timken Axles are salvaged 
and used over again under a new 
chassis. 
Timken Axles outlast the truck.
