My front axle is bent about one and

Il be Strengthened?
This axle should be heated to cher
~ red heat and then Strengthened. The
heat should be applied at the bend
only, and as this Is ten inches from the
king pin bushings there is no reason
why the latter should be heated and
therefore no danger Of them becoming
enlarged. In fact. It Is doubtful
whether they would be enlarged even

Does il make any difference how
many teeth are in bowel gear in 70.
LATHAM a. <h> oAar SAarka in2
The relation of the number Of teeth
on the driving pinion to the number
on the large gear gives the ratio be-
tween the number Of revolutions the
motor makes as compared with the
number the wheels make when the car
is travelling on high gear. Any change
in either the pinion or bevel gear
alters the ratio.
What 10 the cause Of inner tubes b.

This Is caused by neglecting to use
enough tire tale between tube and cas-.
ing. Whenever tube IL placed into
a casing always sprinkle tale over the
inside Of the tire. Tale Is white
powder. which is cheap. and may be
bought at any supply store.
How do you fit babbitt bearings on

If only slightly worn bearings may
be adjusted by removing shims or by
fling the bearing caps. II the bear
ings are scored or worn out Of round
or II new bearings are put in the sur
faces must be scraped.
II the bearing surfaces are In good
condition and not worn out Of shape
slight adjustment should be sufficient
to make them tight There are usually
several shims under the bearing cup.
and by removing these one by one the

are not used the lost motion may be
removed by placing the bearing cap In
