NOTE: Some applications (depending on intake
manifold height) may require the reclocking
of the supercharger volute. If reclocking is
required for your application, loosen and
remove the six 1/4-20 cap screws and retain-
ing plates that hold the compressor housing
(volute) to the gearcase. 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 our service department for further
assistance.
