2. SUPERCHARGER RECLOCKING AND REINSTALLATION
NOTE: Included in this kit is a smaller than originally
supplied supercharger pulley. This new pulley
is recommended to achieve best perfor-
mance results. Removal of the factory sealed
pulley will reduce the supercharger warranty
from three years to one year unless the
supercharger unit (with the original pulley still
attached) and new pulley are sent into
Vortech for removal, installation and re-seal-
ing. If supercharger warranty is not a concern
or if the supercharger warranty has expired,
the pulley may simply be removed and
replaced with the new part supplied.
Hammering/prying etc. on the supercharger
and/or pulley will cause damage to the parts.
Light heating of the supercharger pulley with
a propane torch (if the pulley is tight on the
shaft) will aid removal. A return authorization
number is required before the supercharger
and pulley are sent into Vortech. Call the
Vortech service department at (805) 247-
0226 for return authorization number. Return
freight (ground) will be paid by Vortech.
NOTE: If the compressor housing does not rotate
freely relative to the gearcase, DO NOT
FORCE IT. SERIOUS SUPERCHARGER
DAMAGE MAY OCCUR. The machined mat-
ing surfaces are designed to prevent pressur-
ized air from escaping and have minimal tol-
erances. If the housing will not move or is
very tight, contact Vortech Engineering imme-
diately at (805) 247-0226 and ask for our ser-
vice department for further assistance.
A. Place the supercharger on a clean flat surface
with the drive pulley facing up.
B. Loosen and remove the six 1/4-20 cap screws
and retaining plates that hold the compressor
housing to the gearcase.
C. Carefully rotate the supercharger volute to the
specified position as shown. (See Fig.
2-a.)
D. Evenly re-tighten the six cap screws, torque to 60
in/lbs (5ft/lbs).
E. Remove original 3.80" supercharger pulley from
the supercharger and install the supplied 3.60"
pulley.
