1. 3M EC
1300L (preferred)
2.
Proco
Adhesive
(6205-1)
3. Scotch Grip 2210
b. Remove windlace
retainers. Expose
the door jamb
by rolling back and
taping the windlace.
c.
Disconnect the
door-holder attached
to the lower door
jamb and remove
scuff plate.
d.
Remove the
striker plate.
(Refer to Figure
4-19, Section
A-A.)
e. Remove
the snubber as
follows:
1. Apply
mineral
spirits
to the snubber
to
loosen the
adhesive.
2. Using
a
plastic
scraper
(or other
appropriate
instrument),
scrape
off
the snubber
while
applying mineral
spirits as necessary.
3. With
the snubber
removed,
use
a clean cloth
and mineral
spirits
to remove
excess
adhesive.
f. Installation
of
the door seal
snubber
is as follows:
1. If
the door jamb
paint
is flaking
or is excessively
scuffed,
rub down
with
wet and dry
emery
cloth.
Clean
the surface
with
Prep-Sol
or
equivalent
cleaner
which
will not
leave
an oily
residue.
NOTE
The normal
"tack
time" for
3M EC
1300L is
30 to 45
minutes
at
75°F.
However,
adhesive
which
has "set"
may be
reactivated
by a
clean rag moistened
with
Toluol
or Methylethylketone.
2.
To effect
a clean installation
it is recommended
that
the doorjamb
is
masked off
with tape
as
shown in
Figure 4-19,
View D.
3. Apply
adhesive
to the doorjamb
with a small
brush on
the area
indicated in
Figure 4-19,
View
D.
4.
Apply
adhesive
to the
inside
surface
of the
snubber.
5. Position
the
snubber with
the protruding
leg facing
outboard
beginning
at the lower
center
(+2
inches) of
the doorjamb.
Work
progressively
around the
door jamb
applying
a pressure
to the snubber
to
remove
any trapped
air and to
ensure the
edges are
effectively bonded
to the
jamb.
NOTE
Do not stretch
the
rubber,
especially
in the corner
areas,
as this can
cause
cracks.
6. It
takes approximately
one day for
the bond
to cure.
It is recommended
that
the door
be kept
open
as long as
possible
during this
time to
effect maximum
curing.
7.
Remove
masking
tape if
used, and
clean
off excessive
adhesive
using
a clean
cloth
and mineral
spirits or Toluol.
8. Install
the striker
plate.
9. Reposition
the
windlace and
secure
with retainers
previously
removed.
10.
Install
the scuff
plate and
door holder
previously
removed.
I.
Adjust the door
latch to compensate
for
the snubber, ensuring
a good
door to fuselage
contour
fit
with no
increase
in latching
effort.
12. After
installation,
the door
latches
must be
adjusted to
compensate
for the
snubbers,
ensuring
a good fuselage
contour
fit and
no increase
in latching
effort..(Refer
to latest
revision of
Piper Service
Spares
Letter #365.)
13. After
all adjustments
and curing
have been accomplished,
coat
the snubber
with silicone
- wipe
off any excess.
