2. SUPERCHARGER RECLOCKING AND REINSTALLATION
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 immedi-
ately at (805) 247-0226 and ask for our service
department for further assistance.
NOTE: Included in this kit is a smaller than originally sup-
plied supercharger pulley. This new pulley is rec-
ommended 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 original
pulley still attached) and new pulley are sent into
Vortech for removal, installation and re-sealing. 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 super-
charger 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 depart-
ment at (805) 247-0226 for return authorization
number. Return freight (ground) will be paid by
Vortech.
