Fore/Aft Adjustment Procedure

    Important: Oversized holes in the hinge provide fore and aft adjustment of the hood.

  1. Loosen the hood attaching bolts at the upper hood hinge.

Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.
