FIGURE 94
HORIZONTAL MEASUREMENTS:
Horizontal measurements are taken on a level at the
markings set by the vertical measurements, Figure 95 and
96. They are taken parallel to the floor or roof assemblies
to check the width of the door, windshield, or rear win-
dow openings.
FIGURE 95
For example, the vertical measurements on both front
body pillars and the center body pillars are marked at 12",
24" and 37" upward from the top of the side sill. The
horizontal measurement then would be the distance
BODY MANUAL
between the two center body pillars at marks which are the
same distance from the sill. These measurements are used
in checking the correct distance or spacing between the
body pillars for proper and true openings.
FIGURE 96
DIAGONAL MEASUREMENTS:
The diagonal measurements used in the squaring-up
operations are taken at the markings set by the verti-
cal measurements.
For example:
1. Set one end of the tram on the fixed location at the
bottom of the right front body pillar and adjust the
other end of the tram to the top vertical marking on
the top of the left front body pillar. Lock the tram at
this measurement. Then check between a similar
fixed location at the bottom of the left front body and
the top vertical marking on the right front body pillar:
These two measurements should be the same. If it is
found that there is a difference, it will indicate that
this part of the body has been forced sideways.
To square up this section of the body, apply the body
jack or power tools to the shortest measurements and
force the body in that direction a little more than
one-half the distance between the two measurements.
An approximate additional 3/16" should be allowed
to compensate for the internal strains pulling the
damaged area back after removal of the forcing tools.
