Attaching The Horn to 
a Booster, Booster to a 
Probe, or Horn to a Probe
1.  Inspect  all  surfaces  to  be  joined  for  stress  cracks, 
chips, or gouges. Any of these irregularities will affect 
operation and could lead to further equipment damage. 
Contact  the  Dukane  Ultrasonic  Tooling  Department 
concerning a damaged booster.
2.  Ensure that the mating surfaces of the two components 
are clean and smooth. These surfaces must make inti-
mate contact for the mechanical energy to pass from 
one component to the next. Pitting or a buildup of old 
grease and dirt on a mating surface will interfere with 
the energy transfer and reduce the power delivered. 
3.  Make sure that the stud in the horn or booster is tight. 
See the preceding mounting stud assembly instructions 
for torque specications.
4.  Remove any foreign matter from the threaded stud and 
mating hole.
5.  Apply an extremely thin layer of a high temperature, 
high pressure silicon grease to the surface that mates 
with the horn. The grease will allow both surfaces to 
intimately mate and become acoustically  transparent 
which improves  the  energy  transfer. We  recommend 
Dow–Corning  #4  (or  #111  as  an  alternate). A  small 
packet of Dow–Corning #4 is supplied with the system. 
If you cannot use a silicon–based grease in your facility, 
a petroleum–based grease may be used. However, it is 
likely to leave carbonaceous deposits on the surface, 
and require more frequent joint maintenance. Grease 
may be omitted if mylar washers are preferred on sys-
tems that require frequent changes. Mylar is plastic and 
will creep under compression, so mylar is not recom-
mended  for  system  that  are  not  changed  frequently. 
Failure to follow these instructions, may result in the 
mating surfaces bonding and difculty removing the 
horn from the booster or the booster from the probe. 
Figure 6–5  Stack Assembly Procedure
Tighten
CAUTION
Never leave a horn or booster 
assembly hand tight. Torque 
it to the proper specications 
before proceeding. If the as-
sembly  is  installed  without 
being properly torqued down, 
the  assembly  may  vibrate 
severely, damaging the mat-
ing  surfaces  and  causing 
the  generator  to  overload.
NOTE
Always remove a probe stack from the 
machine in which it is mounted before 
attaching or removing a horn.
