PIPER CHEROKEE SIX SERVICE MANUAL
NOTE
To allow
for manufacturing
tolerances,
it will
be permissible
to use AN960-616 washers
as required to permit
1-1/2 to
2-1/2 threads exposed through the nut.
b. Attach the two
steering rods (two bungee assemblies
on 1974 models and up) to the
nose gear
steering horn with the
bolts, washers and nuts.
c. If removed, connect
the shimmy
dampener to the
steering horn with
bolts, washers
and nuts. A spacer bushing and cotter
pin are required at the body
attachment point.
d. Install the engine and
connect controls. (Refer to Engine Installation,
Section VII or
VIIA.)
e. Attach hoses, wires, and cables
to engine mount tubing, securing
with clamps and
Koroseal lacing
where required.
f.
Check the alignment of the
nose gear per Paragraph
6-12.
g. Remove the aircraft from the jacks.
h. Install the
propeller (refer to Installation of
Propeller, Section VII or VIIA)
and
engine cowling.
6-12. ALIGNMENT
OF NOSE
GEAR.
a.
Place the aircraft
on a
smooth level
floor that
will accommodate
the striking
of a
chalk
line.
b. Place the
aircraft on jacks. (Refer
to Jacking, Section II.)
c. Level
the aircraft laterally
and longitudinally.
(Refer to
Leveling, Section
II.)
d. From the center
of the tail skid, extend a plumb bob
and mark the contact point on
the floor.
e. Extend
a chalk line from
the mark on
the floor below the
tail skid to a
point
approximately
three feet forward
of the nose wheel.
Allow the line
to pass under the
wheel
at the center of the tire. Snap the chalk line.
f.
Clamp the rudder pedals to align
in a lateral position. (Refer to Figure
6-3.)
g. Adjust the rod end bearings of each steering control rod (on 1974 models and up,
adjust rod end bearings
on bungee assembly) to align the
nose wheel with the chalk line and
to
bring the rudder pedals
into neutral
angle fore and aft.
To align the nose wheel
straight
forward, stand in front of
the nose gear and align the center rib
of the tire with the chalk
line or lay a
straightedge along
the side of the tire
and parallel the
straightedge with the
chalk line.
With the aircraft level, the neutral angle
of the rudder pedal is 11 degrees
(14
degrees on 1974 models and up) aft of the vertical line. Place a bubble protractor against a
pedal steering tube
to check this angle. (Refer to Figure
6-4.) One end of each rod must be
disconnected
and jam nuts loosened to make
this adjustment, but do not attempt
to make
the
adjustment by means of one bearing,
but divide the adjustment between the
bearings at
each end of each rod. Check
that rod ends have sufficient thread engagement
by ascertaining
that a wire
will not go through the check hole
in the rod. (Rods without check holes
maintain a minimum of three-eighths
of an inch thread engagement.) Reinstall
rods; safety
and tighten jam nuts.
