Tools Required

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: 

•

Note the position of the crankshaft balancer before removal, Corvette only. The balancer does not use a key or keyway for positioning. Mark or scribe the end of the crankshaft and the balancer before component removal. The crankshaft balancer must be installed to the original position. If replacing the crankshaft balancer, note the location of any existing balance weights, if applicable. Install new balance weights into the new crankshaft balancer, if applicable. Crankshaft balancer weights must be installed into the new balancer in the same location as the old balancer. A properly installed balance weight will be either flush or below flush with the face of the balancer.

•	The Camaro/Firebird crankshaft balancer is balanced as an individual component. It is not necessary to mark the balancer position prior to removal.

•	Do not use the crankshaft balancer bolt again. Install a NEW crankshaft balancer bolt during final assembly.

•	Make sure that the teeth of the flywheel holding tool mesh with the teeth of the engine flywheel.
