When the pressure switch adjustment is complete,
the pressure regulators should be adjusted for the
pressure at which modulation of air delivery should
begin. In this case, that pressure will be 100 psi (6.9
bar) for the spiral valve, and 108 psi (7.4 bar) for the
Sullicon. The regulator is adjusted by loosening the
jam nut on the end of the cone---shaped cover of the
pressure regulator. When the jam nut is loosened,
turn the adjusting screw clockwise to increase or
counterclockwise to decrease the setting.
Above 100 psi (6.9 bar), the regulator should allow
pressure to flow into the control chamber of the spi-
ral valve. Movement of the spiral valve is indicated
by an indicating rod that protrudes from the sump
tank side of the first stage stator. When the rod is ful-
ly extended, the spiral valve is fully open (unloaded
position). The spiral valve rack should start to move
at this time.
Above 108 psi (7.4 bar), the regulator should allow
pressure to flow into the control chamber of the Sul-
licon. The Sullicon lever should start to move at this
time. Cycle the Control System several times and
re---check all pressure settings.

alignment, the tools required are a straight edge, a
measuring scale, one set of feeler gauges, a set of
standard Allen wrenches, one set of standard sock-
et wrenches and a set of dial indicators are recom-
mended.
The first step in coupling installation is assembling
the taper lock bushings to each hub. Proceed ac-
cording to the following instructions for assembly of
the bushings and hubs:
