6.4.9 Crimpers - Change Heat Element/
Thermocouple
1. Lift the guard over the endseal to expose
the crimpers.
2. Disconnect the thermocouple wire on the
backside of the crimper, then disconnect
the heat element wires from the collector
ring.
3. Remove the mounting capscrews which
are holding the crimper to the shaft and
remove the crimper.
4. Remove the two screws in the crimper end
plate and remove the end plate.
5. Slide the element from the crimper. In
some cases it may be necessary to drive
the old element out due to the heat
causing it to seize up. Be careful not
to damage the crimper if this step is
necessary.
6. After the element is removed, the hole in
the crimper should be reamed to clean any
excess material from the hole.
NOTE
Do not ream the hole too large or it will
not heat properly when the new element is
installed. Use a ream 9.525mm (.375 ) in
diameter.
7. Coat the new element with WATLUBE
heat release and heat transfer agent,
Doboy Part #215085, according to the
instructions on the container.
8. Insert the new element into the crimper
assembly.
9. Feed the element wires down through the
hole in the endseal shaft and out to the
collector rings.
10. Place the crimper back onto the shaft,
then attach the element wires to the
collector rings and replace the crimper
end plate.
11. Lower the endseal guard.
12. Run a few sample packages and check
the quality of the seal. Readjust as
necessary.
