5. Position the engine in the mount so the distance from the
front of the firewall to the front of the thrust washer measures
5-5/16" [135mm]. Mark the location of the engine on the mount.
The Great Planes Dead Center Hole Locator (GPMR8130)
works well for this. Drill through the marks you have made on
the engine mount with a #29 or 9/64" [3.6mm] drill bit. Tap each
of the holes with an 8-32 tap.
6. Install the engine onto the mount with four each, 8-32 x 1"
[25mm] socket head cap screws, #8 flat washers and # 8
lock washers.
❏
7. Mark the location on the firewall where the throttle
pushrod will pass through. Drill a 3/16" hole on that mark.
Locate the 24" [610mm] gray plastic pushrod tube. Cut it to
a length of 16". Roughen one end of the tube with 220-grit
sandpaper. Install the un-sanded end of the pushrod tube
into the front of the firewall through the hole you drilled in
the firewall and through the hole inside the fuselage, in the
fuselage former. Apply CA to the roughened end of the
plastic tube, gluing it into the firewall.
❏
8. Locate a .074 x 36" [914mm] pushrod wire. Cut it to a
length of 21" [533mm], cutting off the threaded end of the
wire. Insert this wire into the plastic tube you installed for the
throttle. Install a brass screw lock connector into the throttle
arm, locking it to the arm with the nylon retainer. Insert this
wire into the screw lock connector and the plastic tube you
installed for the throttle. Lock the wire to the connector with
a 6-32 x 1/4" [6mm] socket head cap screw.
Refer to this photograph for steps 8 -12.
❏
8. Locate two 3/8" x 3/8" x 3/8" [9 x 9 x 9mm] balsa blocks and
two plywood pushrod supports. Slide the supports over the
gray plastic throttle pushrod you have installed in the fuselage.
