Background

This procedure describes how to adjust the clearance between the tail gripper spoilers and the drum using shims.

Procedure

Important: Only experienced engineers should perform the following procedure.

Note: During the procedure, apply a drop of Loctite^® adhesive on all the screws for which you are securing parts.

1. Perform a preload sequence.
2. Position the tail gripper assembly so that the middle of the assembly is at 300° by activating the tail gripper and moving the drum.
   
   
   
   
3. Verify that the four tail bar lockers are pressed down as far as possible and that a 0.05-mm shim cannot be easily inserted under the tail gripper.
   
   
   
   
4. If you can easily insert the shim under the tail gripper, adjust the clearance.
   1. Loosen the two tail gripper screws.
   2. Press down on the tail bar locker, pushing it down as far as possible.
   3. When the tail bar locker is pressed down as far as possible, tighten the two screws.
5. Verify that the clearance between the seven tail gripper spoilers and the drum is 0.05 mm.
   
   
   
   
   1. Insert the 0.05-mm shim under the first tail gripper spoiler and slide it from one side of the tail gripper spoiler to the other side. You should be able to slide the shim, but with some resistance.
   2. If the shim slides easily from one side to the other, adjust the clearance.
   3. Loosen the screws that secure the tail gripper spoiler to the tail gripper assembly.

   4. Next to the right tail gripper spoiler screw, press down on the front of the tail gripper spoiler and tighten the tail gripper spoiler screw. Adjust the left tail gripper spoiler screw in the same way.
      Note: If there is not enough clearance, loosen the screw, press on the back of the tail gripper spoiler, and then tighten the screw.

   5. Repeat steps 4a–4d for each of the remaining six tail gripper spoilers.
