PIPER CHEROKEE SIX SERVICE MANUAL
NOTE
Repair Kit, part number 757 023, contains all materials
necessary to replace the rear door window and is available
through Piper Aircraft Dealers or Distributors.
a. Temporarily position new retainer. Using a 1/8-inch drill, drill 16 holes around the
inner panel assembly using the holes in the retainer as pilot holes. Remove retainer and
redrill all 16 holes using a 5/16-inch drill.
b. Temporarily position new window in its recess to determine that sufficient material
has been removed and that it fits properly.
c. Stand the window on edge on a protective surface. Peel the protective masking away
from the edge far enough to permit the application of the sealing tape. The tape should be
applied in such a manner that the approximate center of the tape will contact the edge of
the window.
d. Carefully press tape to contact both sides of the window simultaneously. The tape
should be evenly divided on both sides of window. Cut and trim tape as necessary.
e. Position window in its recess in the door. Gently press outer edges of the window so
that tape will contact the inner surface of the outer panel assembly.
f. Insert 16 wall grip nuts (with screws installed) through holes previously drilled in the
inner panel assembly. Turn screws in clockwise rotation thus activating the locking feature
of the nut. Continue in this direction until the nut is drawn up tight. Avoid excess torque to
prevent stripping threads. Remove screws.
g. Place new retainer into position and secure with 16 screws and washers (AN960-6).
h. Carefully invert the door. Apply a bead of PRC-5000 sealant to the outer perimeter
of the window. Allow sealant to dry before reinstalling door.

outer panel and window, and window and inner panel are
tight. Fresh breaks in bond lines can be sealed using one of
