REMOVAL
OF
CHERRYLOCK
RIVETS.
(Refer
to
Figure
2-4c.)
Should
it
be
necessary
to
remove
an
installed
cherrylock
rivet,
the
following
procedures
are
recommended.
a.
In thick
material
remove
the
lock
by
driving
out
the rivet
stem
using
a
tapered
steel
drift
pin
(Refer
View
1).
NOTE
Do
not drill
completely
through
the
rivet
sleeve
to
remove
a
rivet
as
this
tends
to enlarge
the
hole.
b.
If
the
rivets
have
been
installed
in thin
sheets,
driving
out
the locked
stem
may
damage
the
sheets.
It is
recommended
that
a small
center
drill
be
used
to provide
a
guide
for
a larger
drill
on top
of
the rivet
stem,
and
the
tapered
portion
of the
stem
be drilled
away
to
destroy
the
lock
(Views

and

c.
Pry
the
remainder
of
the locking
collar
out
of the
rivet
head
with
the drift
pin
(See
View
3).
d.
Drill
nearly
through
the
head
of
the
rivet,
using
a
drill
the
same
size
as
the rivet
shank
(See
View
4).
e.
Break
off
rivet
head
using
a drift
pin
as a
pry
(See
View
5).
f.
Drive
out the
remaining
rivet
shank
with
a
pin
having
a
diameter
equal
to
the
rivet
shank
(See
View
6).
