CAUTION
•
Be careful not to file too much; this will reduce the
strength and rigidity of the panel.
•
Do not use the file in one direction only; alternate use
in two directions diagonally opposite each other.
4. Next, file the area so that convex and concave parts are no
longer clearly visible, and at the same time remove small
projections.
5. After once again smoothing the clearly visible dents and
projections by using the hammer and dolly, follow step 4
above.
Alternately repeat hammering and filing until there are file
traces over the entire repair area.
6. Make a solder build-up at the repair.
7. Finally, finish up the solder build-up using a body file.
USING A FRAME STRAIGHTENER
M4090013000044
For serious and extensive damage, when for exam-
ple the damage extends to the frame of members, it
is necessary to first use a frame straightener to make
a rough, overall repair of the body, and then to pro-
ceed to careful repairs of each individual area of
damage. When a frame straightener is used for body
repairs, it is a fundamental principle that the pulling
should be in the direction from which the impact was
sustained, and from the opposite direction. If this is,
in error, not done, previously undamaged compo-
nents will be deformed, and repair may become
impossible.
It is for that reason that it is important to decide upon
the method of repair, especially regarding the initial
overall repair, by following the steps below.
OVERALL ROUGH REPAIRS
1. First, analyze the impact. This means analysis
and consideration of the point of collision, the
speed at the time of collision, and the strength,
weight and shape of the object hit.
2. Then get a complete understanding of the
condition of the existing damage. In particular, if
the damage extends to the suspension installation
components, an inspection must be made to
determine whether or not there is any deviation of
the frame or body alignment.
3. Finally, determine what repair methods should be
used.
•
To what extent will frame straightening and other
overall repairs be necessary in order to restore
the damaged areas to the way they were?
•
At what stage of the repairs should panels adjoin-
ing the components to be frame straightened,
etc., be removed?
•
Decide upon the work steps and restoration
methods to be followed after the rough, overall
repairs are completed.
Select the frame straightener based upon the results
of above, and use it to pull in the appropriate direc-
tion. More than one direction may be appropriate,
depending upon the damage.
If the damage is of a moderate degree or less, it may
be possible to do all that is necessary in one pull.
If, however, the damage is major, that is to say if
repairs must be made to components of the passen-
ger compartment such as the dash panel, etc., it may
be necessary, after completing the first pull, to set up
the frame straightener at a different position and use
it again at that position.
