    Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. 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.

    Important: 

       • Do not use the crankshaft balancer bolt again. Install a NEW crankshaft balancer bolt during final assembly.
       • Ensure that the teeth of the flywheel holding tool mesh with the teeth of the engine flywheel.
