9-2 CHECKING ALIGNMENT OF FRAME
AND SUSPENSION MEMBERS
When
a
frame
has been
damaged
by
a
cci-
dent the follow
ing procedure
ma y be used
t
o
check alignment
of t

the
frame.
This procedure
sh

used to
check a

been
comp
leted.
If
bod

re
moved for re-
pa ir s to
frame, check
frame
as
described
in
par agraph 9-3.
Checks
are to
be
made
with f

with
power plant, body, etc., and car resting on
wheels.
The car
should
be placed on a clean
floor t
hat

sides
of the
front
ends of the frame must be
t
he
same dis-
tance
from
the
floor
; the same
conditi on must
exist
at
r
ear
end of
frame.
Where
points are

of a plumb bob,
it is
desirable t
