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.

Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.
