    IMPORTANT:
    • For manual transmission applications, note the position of the crankshaft balancer before removal. 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.
    • 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.
  7. Remove the crankshaft balancer. Refer to Crankshaft Balancer Removal .
  8. Clean and inspect the crankshaft balancer. Refer to Crankshaft Balancer Cleaning and Inspection .
