A. Loosen and remove the six 1/4-20 cap screws
and retaining plates that hold the compressor
housing to the gearcase.
B. Carefully rotate the compressor housing to the
specified location as shown. (See Figure 2-a.)
C. Evenly retighten the four cap screws, torque to
60 in/lbs (5ft/lbs).
D. Remove original Ø3.47” supercharger pulley
from the supercharger and install the supplied
Ø3.125” pulley.
2. SUPERCHARGER RECLOCKING
NOTE: If the compressor housing does not
rotate freely relative to the gearcase,
DO NOT FORCE IT. SERIOUS SU-
PERCHARGER DAMAGE MAY OC-
CUR. The machined mating surfaces
are designed to prevent pressurized
air from escaping and have minimal
tolerances. If the housing will not move
or is very tight, contact Vortech Engi-
neering immediately at (805) 247-0226
and ask for our service department for
further assistance.
NOTE: Included in this kit is a smaller than
originally supplied supercharger pul-
ley. This new pulley is recommended
to achieve best performance results.
Removal of the factory sealed pulley
will reduce the supercharger warranty
from three years to one year unless
the supercharger unit (with the origi-
nal pulley still attached) and new pul-
ley are sent into Vortech for removal,
installation and re-sealing. If super-
charger warranty is not a concern or if
the supercharger warranty has ex-
pired, the pulley may simply be re-
moved and replaced with the new part
supplied. Be aware that hammering/
prying etc. on the supercharger may
damage precision parts.
