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! If
replacing the solvent tube, install into the at-
omizer 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
“Installing Loop In Tubing” figure) to prevent
tube from becoming pinched when outer shap-
ing air ring is installed. Do not kink the tube
when installing loop (see “Interior/Exterior
Shaping Air Manifold Removal” figure).
Turbine Removal/Replacement
Removal
Remove the turbine retaining ring by using the
spanner wrench (A12088-00), turning the tur-
bine retaining ring in a counter-clockwise di-
rection. Pull the turbine out while rocking it
from side to side.
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.
