1.
Label and cut leads to the coil(s)
being removed. See Figure F.23.
NOTE: To remove a main trans-
former coil, it is necessary to
remove the secondary coil first.
2.
Remove the secondary coil by
breaking the seal caused by the
epoxy paint and lifting the coil up
away from the main transformer
coil.
a.
If the secondary coil is not
being replaced, do not cut the
lead to the secondary coil.
With the lead attached, lift the
coil off the main transformer
coil and bend the coil and lead
to the side.
3.
Remove the main transformer coil.
a.
Take out the insulated wedges
that help keep the coil firmly
seated on the iron E. If these
do not dislodge easily, it will be
necessary to force the coil off
the iron E.
4.
Replace the coil(s).
a.
Be sure to replace all insulated
wedges.
b.
Using a high temperature
industrial epoxy, such as
Lincoln E-1603, “glue the pri-
mary coils in place” by applying
the epoxy to the coil side and
cell insulation opposite the
wedges. Using a high tempera-
ture industrial epoxy, Such as
Lincoln E-1603, “glue the sec-
ondary coils in place” from the
iron to the coil sides.
5.
Test for correct operation before
replacing the transformer assembly
back into the machine.
a.
The primary coils should be
ground tested at 2700VAC for
1 second. The secondary coils
should be ground tested at
1500VAC for 1 second. The
primary to secondary insulation
should be tested at 2700VAC
for 1 second.
