Installing Backing Plates and Reinforcing Service Hinges (Pillar Cracked)

1. Refer to the Doors subsection in the appropriate Service Manual for hinge replacement procedures.

2. Use a spot weld drill or 1/2" rotabroach bit in order to remove the factory hinge welds. When installing backing plates, tack-weld the four nuts to the backing plates before installing them to the cowl. When installing backing plates, order the plates, the attaching bolts and the nuts separately. Refer to the Parts Information.
