2. Supercharger Reclocking and Reinstallation

Modified Clocking

NOTE: Included in this kit is a smaller than
originally supplied supercharger pulley. This
new pulley is recommended to achieve best
performance results. Removal of the factory
sealed pulley will void the supercharger
warranty unless the supercharger unit (with
the original pulley still attached) and new
pulley are sent into Vortech for removal,
installation and re-sealing. If supercharger
warranty is not an issue, 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 a return authorization number.
Return freight (ground) will be paid by Vortech.

NOTE: Boss on volute should line up with oil
feed fitting.

NOTE: If the compressor housing does not
rotate freely relative to the gearcase, DO NOT
FORCE IT. SERIOUS SUPERCHARGER
DAMAGE MAY OCCUR. 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 Engineering
immediately at (805) 247-0226 and ask for
our service department for further assistance.
