H. Install the harmonic balancer puller. Evenly start

the three puller screws (M10 x 1.5). Engage the

forcing screw against the pivot and check align-

ment.

I. 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.

J. With a small amount of silicone on the keyway of

the new harmonic balancer, guide it on the

crankshaft and feel for alignment of the wood-

ruff key and the harmonic balancer keyway.

After the harmonic balancer has been aligned

on the crankshaft, use your harmonic balancer

installation tool to install the new harmonic bal-

ancer. Slowly tighten until the harmonic bal-

ancer is seated on the crankshaft.

2. HARMONIC BALANCER AND CRANK PULLEY INSTALLATION, cont’d.

NOTE: When using the harmonic balancer

puller, pay special attention to alignment

of the forcing screw and pivot. Improper

alignment can result in crankshaft dam-

age.

NOTE: The factory uses a small amount of sili-

cone to seal the crankshaft keyway.

Thoroughly clean the silicone and any

oil residue off of the crankshaft prior to

installing the Vortech harmonic bal-

ancer.

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 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 beginning 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 pul-

ley screws.
