  5. Remove the crankshaft pulley bolts.
  6. Remove the hub bolt and washer from the crankshaft pulley.
  7. Remove the crankshaft pulley.
    NOTE: To prevent damage to the end of the crankshaft when using a crankshaft balancer removal tool install a bolt in the crankshaft. Use a shorter bolt with the same threads as the crankshaft balancer bolt. This bolt will allow a place for the tool to push against. The shorter bolt is to keep from going past the threads in the crankshaft and damaging the crankshaft threads.
  8. Position the J 24420-C  puller tool onto the crankshaft hub.
