4. CRANKSHAFT PULLEY/SUPERCHARGER DRIVE PULLEY
A. Remove the rubber inspection plug on the left rear of
the block to make the flexplate accessible. Using an
18mm socket and a 1/2” drive ratchet, rotate the en-
gine until a flexplate nut is visible. Place a 14mm deep
socket and extension on the flexplate nut and rotate
the engine counterclockwise until the socket engages
with the top of the access hole. This will block the
movement of the crankshaft allowing the bolt to be
loosened. This operation may require the assistance
of another person. Remove the center balancer bolt.
B. Install the harmonic balancer puller. Evenly start three
puller bolts (not supplied - 8mm x 1.25 on the 4.6L
and 10mm x 1.50 on the 5.4L). Engage the forcing
screw against the pivot and check alignment.
C. After ensuring the puller is properly aligned on the
face of the crank, slowly tighten the forcing screw until
the harmonic balancer has been removed.
D. With a dab of silicone on the keyway of the new har-
monic balancer, guide it on the crankshaft and feel for
alignment of the woodruff key and the harmonic bal-
ancer keyway. After the harmonic balancer has been
aligned on the crankshaft, use your harmonic balancer
installation tool to install the new harmonic balancer.
Slowly tighten until the harmonic balancer is seated
on the crankshaft.
NOTE: This process can be done with the fan
shroud and radiator in place providing your
balancer puller is equipped with a 5” or
shorter forcing screw. Removing the fan
shroud and the radiator will allow easier
access to the crank pulley and the front of
the engine.
NOTE: When using the harmonic balancer
puller pay special attention to alignment
of the forcing screw and pivot, improper
alignment can result in damage to the
crankshaft.
NOTE: The factory uses a small amount of sili-
cone to seal the crankshaft keyway.
Thoroughly clean the silicone residue
off of the crankshaft prior to installing
the Vortech harmonic balancer.
NOTE: The use of blue Loctite is recom-
mended for all harmonic balancer and
crank pulley bolts.
