3. Install the puller flange disc onto the puller center screw assembly, making sure the shiny or
bearing side of the disc is against the flange or shoulder on the puller body. The puller body
should be threaded onto the puller center screw assembly. The concave side of the puller
flange disc should be facing the end of the puller center screw assembly that contains the
notched puller adapter. See figure g.
4. Match slots on the puller flange disc to the holes in the harmonic balancer to determine the
number of bolts that can be installed. Adjust the puller flange disc position on the puller
center screw so that when installed, the puller flange disc is seated against the harmonic
balancer. Select bolts that will thread easily (by hand) into the holes in the balancer and be
long enough to reach the balancer when installed through the slots in the puller flange disc.
5. Install washers to the bolts. Install the puller assembly to the harmonic balancer, and install
and tighten the bolts. In the example shown, two bolt holes in the balancer line up with
the slots in the puller flange disc and have been installed and tightened. See figure h. Note
that you should use a ratchet or end wrench to thread the bolts securely into the harmonic
balancer.
6. Hold the hexagonal flats on the body of the puller body with an end wrench or adjustable
wrench, and using an end wrench or ratchet, tighten the puller center screw assembly. See
figure i. Keep turning the puller center screw assembly until the harmonic balancer becomes
loose on the crankshaft and is ready for removal. Grasp balancer firmly with both hands and
carefully remove. See figure j.
