NOTE: Some applications (depending on intake manifold

height) may require the reclocking of the super-

charger volute. If reclocking is required for your

application, loosen and remove the six 1/4-20 cap

screws and retaining plates that hold the com-

pressor housing (volute) to the gearcase. If the

compressor housing does not rotate freely rela-

tive to the gearcase, DO NOT FORCE IT.

SERIOUS SUPERCHARGER DAMAGE MAY

OCCUR. The machined mating surfaces are

designed to prevent pressurized air from escap-

ing 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.
