4. Return wheel to center, make sure cam follower is not contacting the cam.
5. Jack the aircraft (Jack Aircraft) or support the nose as follows:
a. Remove the main landing gear 15A fuse from the overhead console. Save this fuse.
c. Fold the wings of the aircraft. This will move the center of gravity aft so that it is easier to lift the nose up and down during the NLG rigging checks.
d. Connect battery charger to the charging terminals. The charger used must have a selectable Lithium charging mode.
e. Have a foam block or equivalent nearby that can be placed under the aircraft on the keel aft of the NLG wheel well that will allow the nose wheel of the aircraft to have approximately one inch or more clearance from the ground. This block will need to be removed numerous times during the procedure.
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 and thrust washer from bottom of leg.
