L. Remove the handle mechanism housing complete with torque tube crank (14) and the torque tube from the door. This step is necessary if the distortion that necessitated the replacement of a hinge arm may also have resulted (to a less noticeable extent) in the distortion of the torque tube. Even a slight bend in the torque tube, or in one hinge arm, will put the several bearings of the mechanism out of alignment, thus necessitating heavy torque on the operating handle.
4. Install Galley Service Door Hinge Arms
A. Check that O-rings (4, Fig. 402) are in good condition and are seated properly in the grooves of hinge link pin (1). Grease the bearing surfaces of the hinge link pins.
