the face of the crank, slowly tighten the forcing
screw until the harmonic balancer has been
removed.

the new harmonic balancer, guide it on the
crankshaft and feel for alignment of the wood-
ruff key and the harmonic balancer keyway.

HARMONIC BALANCER AND CRANK PULLEY INSTALLATION, cont’d.
NOTE:
When using the harmonic balancer puller, pay special atten-
tion to alignment of the forcing screw and pivot. Improper
alignment can result in crankshaft damage.
NOTE: The factory uses a small amount of silicone to seal the crank-
shaft keyway. Thoroughly clean the silicone and any oil resi-
due off of the crankshaft prior to installing the Vortech har-
monic balancer.
K. Remove the installation tool and place the su-
percharger drive pulley and spacer on the front
of the harmonic balancer. (See
Fig. 2-a.) Feel-
ing for alignment, start the supplied M12 x 1.5 x
65mm center screw and rotate the supercharger
drive pulley until the three screw holes are
aligned. Start the three M10 x 1.5 x 40mm cap
screws with washers, evenly tighten all begin-
ning with the center screw. Torque the M12
screw to 80 ft/lbs and the M10 screws to 25 ft/
lbs.
L. Reinstall the rubber inspection plug (if previ-
ously removed) and the accessory drive belt.
Do not reinstall the fan and fan shroud at this
time.
NOTE:
The use of Loctite blue is recommended for all harmonic
balancer and crank pulley screws.
