remove and replace harmonic balancer

2 Answers

It simply has a large bolt in the center, make sure you have the exact right size socket, if manual put it in gear and set parking brake, engine must not be allowed to turn. And some, yours I don't know, have left handed threads. Then you will most likely need a puller, similar to a ordinary wheel puller but specifically made for H/B's, available to rent at parts houses

I also found this, if you want to use a kit. Locate the large metal piece from the harmonic balancer removal kit. This piece looks like the webbing on the foot of a duck, and is therefore commonly referred to as a "duck's foot." Thread the large threaded rod included with the removal kit through the center of the duck's foot. Note that one side of the duck's foot is flat while the other side is curved. The flat side faces the engine. Therefore, the threaded rod should be threaded into the center. Locate the three bolts for the harmonic balancer included in the kit. These bolts will thread through the three holes that surround the face of the balancer itself. Insert each bolt through the slotted portions of the duck's foot. Use a wrench to secure each of the three bolts through the three holes of the balancer. Secure the bolts by turning the bolts in a clockwise direction. Securing these bolts will attach the harmonic Locate the bolt-head on the end of the threaded rod that was inserted through the puller earlier. Remove the harmonic balancer by attaching a wrench to this bolt-head and slowly turning the threaded rod in a clockwise direction. By turning the threaded rod, the puller will slowly pull the balancer until it has been removed from the engine.
