Mark the location where the nozzle is to be b.
installed, as determined during system design.
Drill a 0.187 inch (4.75 mm) through the wall to the c.
bearing point.
NOTE
: Steps “d” and “e” do not apply to the easy to replace nozzle
assembly. If this assembly is used proceed to step f.
Using hole drilled in step “c” as a pilot, drill a 0.516 d.
inch (13.1 mm) hole as deep as possible without
breaking through the machining head wall.
Tap 0.516 in (13.1 mm) hole to 9/16-18 UNF e.
For easy to replace nozzle assembly, 484-090- f.
193, omit steps “d” and “c” and drill 19/32 inch
(15.08 mm) clearance hole as deep as possible
without breaking through head wall. Using adapter
mounting plate as a template, drill and tap two 1/4-
20 holes for attaching screws.
Drill a minimum 1/8 inch (3.2 mm) hole through the g.
machining head beneath each bearing pocket to
allow for drainage.
Assemble machining head. h.
2.3.2.3
Installation of the nozzle tube requires that the
machining head preparation steps be completed as
discussed in paragraph 2.3.2.2. Nozzle tubes are
shipped in 10-inch lengths and must be cut to proper
length for each instal lation. Figure 2-7 shows a typical
installation of a nozzle tube and should be referred to
during the following procedure:
Determine length of nozzle tube required by a.
reviewing machining head prints. This is dimension
“L” on Figure 2-7 Allow 0.625 inch (15.9 mm)
extra length for flare and internal length on nozzle
assemblies.
CAUTION:
When flaring nozzle tube, use extreme care to avoid
splitting the lip of the flare.
Cut nozzle tube to desired length with cutoff wheel. b.
Using a modified flare tool 485-000-090, flare
noz zle tube to a 45 degree angle and 0.190 inch
diame ter.
Remove flare nut and oil nozzle retainer from body. c.
Oil nozzle retainer has a 0.125 internal hex for
removal with an allen wrench.
Insure free-air-flow through nozzle tube; then install d.
it in body and secure with oil nozzle retainer. Note
that nozzle tube cross section is D-shaped and will
only enter body one way. Notches on hex portion of
body indicate outlet hole position.
Place locknut and thread seal on body and install e.
body into 9/16-18 UNF hole in machining head.
