Task Instructions
1. Use standard practices to remove the forward landing gear door assembly.
2. Orient the nose wheel 180° from the natural in-trail position.
3. Wrap safety wire from end to end around the 750-2-120 nose wheel centering gas strut to prevent it from extending.
4. Return wheel to the in-trail position, making sure cam follower is now free from contact with the cam.
5. Use a 1/8 hex wrench to remove the 93615A432 socket head screw and washers holding the cam follower to the ICA010386 centering bracket.
6. If needed, assemble a new cam follower by applying LOCTITE® 603 to the outer diameter of a SFR4ZZ bearing and pressing it into the bore of a ICA010387 cam follower. Allow cure time per the LOCTITE® instructions prior to handling.
7. Coat a 93615A432 socket head screw with Tef-Gel® and assemble the cam follower, NAS1149C0463R washer and 91525A323 washer to the centering bracket. Be careful to orient the cam follower so that screw head bears against the flange side of the SFR4ZZ bearing (larger outer diameter side). Torque the screw to 25 in-lbf.
8. Remove the safety wire installed in Step 3.
9. Perform the verification steps below and correct any deficiencies.
10. Use standard practices to install the nose landing gear forward door assembly.
Verification Method
1. Lift the nose of the aircraft so that the nose tire is clear of the ground. Rotate the nose wheel 360° left and right and confirm smooth motion.
2. Rotate the nose wheel left and right and confirm that the wheel self-centers to the in-trail position. Lower the nose back onto the ground.
