Service Procedure to Install Plates, Reinforcing Existing Hinges
1. Refer to Service Manual, Section 10A1 Doors for Hinge Replacement procedures. Use existing hinges if they are not damaged in place of new
hinges.
2. Experienced technicians have advised that they have found it easier to use a spot weld drill to oversize the four holes and then tack-weld the
four bolts to the back plate before installing it into the cowl. This prevents the technician from having to hold the plates during hinge
adjustment. A couple of peens to the pins also helps secure them better in the hinge, and a spot of Loctite(R).
