S-7S FIREWALL ASSEMBLY AND INSTALLATION
ASSEMBLY
(BEFORE COVERING AND PAINT OF FUSELAGE)
NOTE: Parts call out for items other than those shown on the Firewall
Installation parts page are referenced in Section 003 - Engine.
1.
The metal firewall is supplied pre-cut. Most required openings are cut.
Some minor adjustments on some of the holes might be required to
achieve a perfect fit.
IMPORTANT: The firewall is NOT symmetrical. Pay
attention to the orientation.
2. Check fit of firewall to the related points of the fuselage cage at the eleven
locations shown in
FIGURE 01H-02 . The firewall attaches to the fuselage
frame at these points. Use an appropriate size bolt to pin the firewall in
position. Adjust holes as required to achieve fit. It is possible to adjust hole
size by filing or using a lubricated Unibit step drill.
3. Refer to FIGURE 01H-03 . Fabricate the firewall closeout as shown to fit
the firewall in the corresponding position. Use the provided raw stock. The
hole in the closeout will later be used to route the electrical wiring to the
engine compartment.
4. Rivet the closeout to the firewall and install the rubber grommet.
5. Match drill #11, the two pre-drilled holes in the Oil Tank Mount Bracket to
the corresponding fuselage attach points and cleco. See
FIGURE 01H-05
for details. Transfer drill the lower mount brackets from the aft # 11, using
the fuselage tabs as a guide. Remove Oil Tank Mount Bracket. Mount
Bracket will later be riveted in place.
6. Fabric may be glued to the aft side of the firewall for aesthetic reasons. If
you choose to install fabric, or any kind of soundproofing, now is the time
to do so. Make sure that anything you install does not interfere with the
mounting of the firewall or changes the position of it. Burn through all hole
locations with a hot knife or soldering iron.
