TAIL WHEEL, NOSE GEAR AND TAIL TIE-DOWN
ASSEMBLY AND INSTALLATION
NOTE: Tail Wheel, Nose Wheel and Tail Tie-Down installation is covered in this
section. Fuselage should be covered and painted before final installation.
Refer to
SECTION 10 - OPTIONS
for 10" Tail Wheel.
TAIL WHEEL INSTALLATION
1.
Bolt the tail spring to the tail wheel assembly. Refer to the parts drawing.
NOTE: It may be necessary to lightly file or grind the tail spring to fit within
the spring mount channel.
Do
NOT
modify the channel to obtain the
proper fit as rotation of the tail wheel swivel block may occur, producing
poor directional control.
2.
Bolt the tail spring/ tail wheel assembly to the fuselage as per parts
drawing. Refer to
FIGURE 01B-02
.
IMPORTANT: Be sure the crown of
each Gear Strap is oriented toward the tail spring.
3.
Fabricate 2 small spacer bushings from raw stock provided as shown in
the parts manual.
4.
The 2 Attach Tangs bolted to the Pillow Block Strap must be modified
before bolted in place. For parts callout and modification of these tangs
refer to
HORIZONTAL STABILIZER & ELEVATOR ASSEMBLY &
INSTALLATION
. It is also possible to only finger tighten these two bolts
and to attach the tangs later, when the tail is installed.
5.
During final assembly, it is important that all bolts retaining the tail spring
are tight.
CAUTION: Check the tightness of these bolts after the first 10
hours of flying.
IMPORTANT: There must also be a minimum clearance
of 1/4" between the tail spring and the bottom edge of the rudder spar.
Refer to
RUDDER SYSTEM ASSEMBLY & INSTALLATION
for
instructions on installing the rudder. If there is not sufficient clearance,
space the tail spring away until the minimum clearance is obtained. This
is done by the addition of an aluminum plate between the tail spring and
the fuselage. Longer bolts may be required to do this.
6.
Install the control linkage as per the exploded view drawing. The linkage
will be attached to only the tail wheel at this time. Refer to the
RUDDER
SYSTEM ASSEMBLY & INSTALLATION
for final assembly and
adjustment of the linkage.
7.
The tail wheel is full swivel. This allows pivot turns using brakes or full
rudder deflection. A cam mechanism allows it to engage for steering.
8.
If the tail wheel leans, shim the tail wheel to run vertical.
