Installing Reinforcement Plates

(To be performed on BOTH front door guide loops when EITHER front door guide loop is cracked)







1. Using the "DRILL OPERATION" side of the Magnetic Inspection/Drilling Fixture J 39425-4, place the guide loop in fixture (see View E).

2. Locate two holes in the guide loop late on either side of the threaded stud. While holding the guide loop in the fixture with palm, use a 3/16" drill bit to drill through the black plastic material (see View F).





3. Use T-handle Cutting Bit J 39425-1 to remove all black plastic material from in and around the holes in the guide loop, as shown in View G. This creates two circular cutouts in the lower corners of the triangular are on the back side of the guide loop.

NOTE:
Turning the handle back and forth while applying downward pressure has been found to do a better cleaning job than full rotation of the handle.





4. Install the reinforcement plate studs into the holes in the guide loop. Ensure the reinforcement plate is completely seated by firmly pressing the plate into the cutout area (see View H).

5. Reinstall the guide loop (with the reinforcement plate in place) using the rubber washer removed previously, and the new nut supplied in the reinforcement kit. Torque nut to 28 N-m (21 lb.ft.). Reinstall the nut cover. See View I.

6. Repeat the reinforcement plate installation on the opposite front door guide loop. Then install a Campaign Identification Label.
