Be sure the component lead is straight and
free of solder..
Push it gently back through
the hole until some of it shows on the other
side,
Solder carefully but rapidly to pre-
vent chassis damage.
REPLACING COMPONENTS
3.
Components can be replaced with less
chance of damage to the chassis than the
removal and rew iring of one of the leads.
Remove as follows: Clip the leads close to
the body of the component.
Heat the fillet
and gently push the w ire through until the
hook may be clipped off. Clip the hook off
(on the soldered side) with sharp cutters.

Fig. 8 - Removing Lead
After removing the leads, prepare the chas-
sis for the new component as explained in
Fig. 7, paragraph 2"
To replace the component, fold the leads on
the new part to the same spacing as the
mounting holes. Insert the part and fold the
leads under the chassis to hold the compo- (-
nent firmly against it.

Installing New Component
Clip off the excess wire.
Place the iron on
both the component lead and fillet.
Solder
carefully and rapidly to prevent damage to
the chassis base.
If
one of the conductors
is damaged, it is seldom necessary to scrap
the printed chas sis. Lay a small piece of
wire (#18 to 24 ga.) across the break and
solder each end to the conductor.
If
a fillet is pulled loos e, break it off to get
rid of the loose end.
Fold the new compo-
nent lead to lay on the conductor and solder.
If
the component lead is too short, solder in
i
l
another piece of w ire to bridge the gap.
Pr inted chassiS construction places no strain
on repairs of this nature, thus, soldering
alone will provide sufficient mechanical
str-ength even with heavy shock and vibra-
tion in almost every case.
The base material used on the printed chas-
sis is the best available for this service.
The two
OZ.
copper is twice as heavy as us-
ed in average applications of this type of
equipment.
This assures reliable service
and repair,
if
and when required.
