Great Planes PT-40 MkII Kit - GPMA0118 - Manual (Page 23)

11. From the other piece of outer pushrod tube, cut the
nose steering guide tube. It should be flush with the front
of the firewall and extend 1/2" aft of F-2. Temporarily install
the nose steering guide tube in the firewall and F-2.
❏
12. Cut 14" from the threaded end of a 36" threaded
wire pushrod (after cutting you should have a 14" long
piece of wire threaded at one end and a non-threaded
piece 22" long). The threaded end wire is the throttle
pushrod and the non-threaded piece is the nose gear
pushrod. Screw a ball link about 14 full turns onto the
threaded pushrod wire. Save the nose gear pushrod
for later.
❏
13. Insert the throttle pushrod through the pushrod tube.
Make one downward bend in the pushrod so that the ball
link will meet the ball stud on the engine without binding.
Don’t snap the ball link onto the ball until later. Bend the
wire away from the fuselage side about 1" aft of F-2. The
final adjustments will be done during the radio installation.
❏
1. Remove the engine from the engine mount. Slide a
5/32" wheel collar (included with this kit) with a set screw
installed on the nose gear, then install the nose gear into
the engine mount so 1/4" protrudes above the engine mount.
❏
2. Position the wheel collar so it is snug against the
bottom of the engine mount, then temporarily tighten the
set screw to lock the wheel collar in position.
Look ahead to
the photo at step 5 for more information.

3. Use your “Z-bend” pliers or follow the Expert Tip
that follows to make a “Z-bend” near the end of the
non-threaded wire left over from step 12.

A. Bend the wire. This bend should be about the same
angle as the one shown in the photo.
HOW TO MAKE A Z-BEND WITH REGULAR PLIERS.
B. Make the second bend about 1/8" ahead of the first to
form the “Z.”
C. If there is any extra wire, cut it off so there is only
3/16" past the bend. File the burrs off. Always wear
safety glasses when cutting wire. While bending, push
the wire toward the pliers.
D. If you didn’t like the way that the Z-bend came out and
you have enough wire, cut it off and try another.
