7-13. ALIGNMENT OF NOSE LANDING GEAR.
a. Place the airplane on a smooth level floor that will accommodate the striking of a
chalk line.
b. Ascertain that the nose gear is properly adjusted as given in Paragraph 7-12.
c. With the landing gear in the down-locked position, weight proportionally on the
nose gear and the nose wheel facing forward, adjust the steering bellcrank. The bellcrank is
attached at the lower front of the engine mount directly aft of the gear housing and may be
adjusted by loosening its attachment bolt and sliding the bellcrank for and aft until it clears
each steering arm rollers by .03 of an inch. Retighten the attachment bolt.

point on the floor.
g. 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 centerline of the tire. Snap the chalk line.
h. Clamp the rudder pedals to alignthem in a lateral position. Ascertain that the rudder
pedals are in their neutral position. (Refer to Figure 7-4 and Figure 7-5.)
i. Adjust the rod end bearings of each steering control rod to align the nose wheel with
the chalk line and to bring the rudder pedals into neutral angle fore and aft.
j. Install the steering push rods on the rudder pedals. Adjust the rods so the lengths are
both the same and the rudder pedals are at their neutral position.
k. 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 chalkline.
