LANDING GEAR / NOSE LANDING GEAR 14-69
CHANGE C2 ICON A5 / MAINTENANCE MANUAL
1. Chock the main wheels.
2. Orient the nose wheel 180° from the natural in-trail position.
3. Wrap safety wire around the nose wheel centering gas strut to prevent it from extending.
4. Return wheel to center, make sure cam follower is not contacting the cam.
5. With two people, elevate nose of aircraft. Place a foam block underneath the hull of the aircraft,
just aft of the aft nose gear doors. The nose wheel should be off of the ground with enough room
to slide the nose gear fork out of the nose gear leg. An alternate to this method is to lift the
aircraft on jacks. (See “Empty Weight and CG Measurement While on Jackpoint Scales” on page
3-32.)
6. Remove the cotter pin from the top of the nose gear steering pivot, then remove the castle nut
with a 1-1/8 wrench.
7. Remove the Belleville/flat washer stack, making note of its stack sequence for reference during
re-installation.
8. Remove the nose wheel fork assembly out of the bottom of the leg.
9. Place ICON nose gear bearing installation/removal tool into position. Insert should be placed on
the top of the leg with the cup on underneath side of gear leg, centered around on bearing. Place
the all-thread inside the center of the tool. Spin the top nut down until the tool holds position
snugly on gear leg. Start turning the nut on the bearing insert, while holding the nut on the cup
stationary. Once enough pressure is applied the bearing should break free. Press bearing out
through the gear leg.
10. Remove nose gear bearing installation/removal tool.
11. Discard the NLG bearing.
12. Inspect NLG fork pivot shaft for signs of galling/wear.
VERIFICATION METHOD:
