HEADS.
NOTE: To gain access to the landing gear, remove access panels located in the forward baggage
compartment.
a. Place airplane on jacks.
b. Disconnect leads to landing lights.
c. Retract the landing gear far enough to permit unlocking the downlock mechanism.
d. Disconnect downlock spring from aft end of gear actuating cylinder.
e. Disconnect upper drag link from the strut housing.
f. Disconnect the actuating cylinder from the strut housing.
g. Remove attaching hardware at strut housing pivot point and remove landing gear from the airplane.
h. To remove upper and lower drag links, disconnect downlock link from lower drag link and
disconnect lower drag link from its attachment point.
7-11. INSTALLATION AND RIGGING. (Refer to Figures 7-2 and 7-2a.)
NOTE: See Lubrication Charts, Section II, and ensure affected parts of the landing gear such as
bearings, bushings, etc, are lubricated prior to and following assembly.
a. Position the gear assembly between the mounting points, making certain the tiller roller is properly
inserted in the steering arm channel.
b. Align the mounting points of the strut with those on the mount and install the appropriate hardware.
The bolt heads should be inboard, with the nuts outboard and just loose enough to allow the gear to
swing freely.
c. If necessary, assemble the drag links. Installed or removed, use the appropriate instructions in this
section to check their rigging.
d. The drag links are installed with their over center stops facing up, the upper link connection aligned
with the right side of the gear's upper ring block and the lower link connection positioned in its
bracket on the bottom rear of the nose gear mount (see Figure 7-2). With the links in position,
install the connecting hardware and move the gear to assure free movement.
e. At the actuator housing attachment assembly (see Sketch D, Figure 7-2), disconnect the retention
spring from the retraction link fitting.
f. Position the gear in its down locked position and check that the drag links have fully extended to
their through center position with the stop surfaces in contact.
g. With the actuating piston rod extended, adjust the piston rod end such that 0.25 of an inch of rod
travel remains in the actuator before full extension. Connect the rod end to its mount on the gear
assembly. The retraction link to which the actuator is attached should be near its stop.
h. Reconnect the retention spring to the retraction link fitting.
