9.
Insert the hose and fitting through the crimp dies. Align
the foot on the coupling stop so that the foot rests on
the top of the crimp die and also against the end of the
fitting ferrule. Be sure the foot on the coupling stop is
against the end of the ferrule and not resting on the
bump of the tube above the ferrule.
10.
Manually depress the compression ring, closing the die
set until the hose and fitting are held loosely in the die
set. Seat the compression ring evenly on the die set
Each die set has a limited range of diameters for which
a satisfactory crimp can be obtained. Always consult the
Continental ContiTech Crimp Specification Manual for
selecting the correct die set.
11.
Recheck the fitting for the correct alignment in the die
set and depress the start/stop switch. Hold the start/
stop switch until the automatic stop switch shuts the
pump off. Release the start/stop switch and allow the
pusher to return to the retracted position.
12.
Check the crimp diameter of the finished assembly
with a caliper or micrometer to be certain that it is
within the specifications as outlined in the Continental
ContiTech Crimp Specification Manual. The caliper
measurement should be taken in the crimp groove
between the ridges as shown.
NOTE: To properly measure the crimp diameter on
“
AC” style fittings, your caliper should be a style having
notched blades as shown here:
13.
Check the completed
assembly to be sure that
the hose is still visible
through the witness
hole on the fitting. Also,
the crimp grooves
should be centered on
the fitting ferrule.
If the crimp grooves are too near the fitting end of the
ferrule, or too near the hose end of the ferrule, the fit-
ting may not seal properly and the assembly could leak.
If your finished crimp assembly resembles either of the
two examples shown below, the end of the ferrule was
not properly positioned against the coupling stop foot,
or the coupling stop foot was not resting on the top of
the die set when crimped. A new assembly should be
crimped, being sure to follow the procedures in Step 9.
CAUTION: The notches on the die set must be
completely covered by the compression ring prior
to starting the crimp. If the notches are showing,
you must go to a larger die set. Crimping with an
incorrect die size could result in personal injury.
