the factory crank pulley.

B. Rotate the previously installed crank pulley

spacer to align the three mounting holes. Install

drive belt and install between the

crank pulley and supercharger pul-

ley. Using a 1/2" ratchet, apply

5. CRANK PULLEY ANd SUPERCHARGER dRIVE PULLEY INSTALLATION

NOTE: If the supercharger drive pulley will not slide

onto the shaft DO NOT FORCE IT. Light

heating of the supercharger drive pulley with

a propane torch will aid in installation.

NOTE: Take care to ensure that all pulleys and spac-

er are piloting correctly and seated flat against

their mounting faces.

NOTE: Two crank pulley spacers are provided in this

system. 4GP017-031 (3.695" long) is to be used

for serpentine drive systems. The 4GP017-041

(3.293" long) is to be used for V-belt applications.

NOTE: The bearing retaining ring on the pulley should

be facing the pulley spacer to properly clear

the “thick” retaining washer. (See Fig. 6-d.)

C. Install all applicable accessory belts at this time

and tension using the appropriate belt tension-

er for your application.

D. (10-Rib Units Only) Lightly grease the super-

charger input shaft and/or the supercharger

drive pulley bore. Install the pulley onto the

supercharger input shaft and rotate the pulley

to align the keyways. Slide the square key into

the keyway. Install the pulley retainer assembly

into the input shaft and hand tighten.
