*** 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 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 tol-
erances. If the housing will not move or is very
tight, contact Paxton Automotive immediately at 888
9-paxton and ask our service department for further
assistance.
