❏
1. Cut the glow engine mount template from page 35. Use
tape or spray adhesive to hold the template to the firewall.
Align the vertical and horizontal lines on the template with the
embossed lines on the firewall.
❏
2. Use a large T-pin or a wire sharpened on the end to
transfer the center of each bolt hole mark on the template
into the firewall.
❏
3. Drill through the holes on the template. The two holes
in the center of the mount template are for your fuel lines to
exit the firewall.
❏
4. Mix a small amount of 30-minute epoxy. Apply a few dabs
of epoxy to the front of four 8-32 blind nuts. Hold the blind nut
against the back of the firewall and thread an 8-32 x 1-1/4"
[32 mm] bolt with a #8 washer into the blind nut. Tighten the
bolt to draw the blind nut into the wood. Be careful to avoid
getting excess epoxy into the threads on the blind nuts.
❏
5. Mount the engine mount to the firewall as shown using
four 8-32 x 1-1/4" [32 mm] SHCS, #8 flat washers and #8
lock washers.
❏
6. Place the engine in the mount. The distance from the
firewall to the front of the drive washer is 7-1/4" [184 mm].
Use a Great Planes Engine Hole Locator or a small drill bit
to mark the engine mounting holes into the engine mounts.
❏
7. Take the engine off the mount. Drill 9/64" [#29] holes
at the marks. Use an 8-32 tap to cut threads into the holes.
❏
8. Mount the engine to the mount with four 8-32 x 1"
[25 mm] socket head cap screws, four #8 flat washers and
#8 lock washers.
