Step 14
Slide the plywood standoff forward on the housing to
a position just ahead of the cutout in the side of the
motor box. Let it find its natural position and glue it in
place with medium CA.
Step 16
Insert a 9/64-inch drill bit in the engine lug holes and
twist it by hand to mark the engine mount locations.
You may find it helpful to clamp the engine to the
mounts during this step so that it cannot move.
Step 18
Place a #6 steel washer on each of the 6-32 x 1-inch
Allen head machine screws.
Step 15
Place the fuselage left-hand side down in a suitable
stand. Set the engine on the mount and position it so
the face of the drive washer is 4 5/8 inches from the
forward face of the firewall.
Step 17
Remove the engine. Use a 9/64-inch bit in a drill motor
to drill the holes in the engine mount. Make sure you
keep the drill perpendicular to the mount while drilling
the holes.
Step 19
Place the engine on the mounts and insert the screws
into the engine lugs and mount. Thread an 8-32 nylon
lock nut onto each of the screws and use a 7/64-inch
hex wrench and 5/16-inch wrench to secure the
engine to the mount.
