Rear Shroud Removal/Replacement
Removal
Loosen flat head screws until they are loose.
Screws are captured in the shroud and will
come off with it as an assembly. Pry the edge
of the shroud away from the atomizer exten-
sion while pulling it away from it. Repeat for
other side.
Replacement
Align the cut out notch of the shroud with the
high voltage cable access hole of the atomizer
extension. Snap into place and tighten all flat
head screws to 3-5 lbs.- in. (.34-.56 Nm)
torque.
Shaping Air Manifold, Solvent Tube Re-
moval/Replacement
Removal
Remove the outer shaping air ring by turning if
off by hand in a counter-clockwise direction.
Remove the fitting, ferrule, and exterior cup
wash line from the inner shaping air manifold
by turning the fitting in a counter-clockwise
direction using a 3/16" end wrench. Loosen
set screw on inner shaping air manifold with a
5/64" hex wrench enough to allow manifold to
be removed from the turbine body. Remove
the inner shaping air manifold by turning it off
in a counter-clockwise direction. A 1/4-20
threaded screw may be screwed into the cup
wash port to provide additional leverage to re-
move the inner shaping air ring.
Reassembly
(Lightly lubricate all O-rings prior to assem-
bling.) Carefully install the inner shaping air
ring onto the turbine threads. Tighten in a
clockwise direction until it seats against the
turbine. Tighten set screw to 5 lbs.- in. (0.564
Nm) torque to prevent shaping air ring/
manifold from rotating. Do not over tighten!
(Use a 5/64" hex key wrench.) If replacing the
solvent tube, install into the atomizer body first
and tighten with a 3/16" end-wrench. Before
installing the other end into the inner shaping
air ring, check the position of the 1/4-20
threaded hole. If it is less than 180° from the
fitting installed in the atomizer body, you must
install a loop (as shown in Figure 26) to pre-
vent tube from becoming pinched when outer
shroud is installed. Do not kink the tube when
installing loop.
Turbine Removal / Replacement
Remove the turbine retaining ring by using the
wrench (A12088-00), turning the turbine re-
taining ring in a counter-clockwise direction.
Pull the turbine out while rocking it from side to
side.
