MICROMETER ADJUSTMENT
1.
Loosen the jam nut with a 7/16” open end
wrench.
2.
Hold the flats on the micrometer stem
with a 5/16” open end wrench while
twisting the stem foot on the bottom of
the micrometer.
Twist the stem foot to the right
(up into the micrometer) if the
machine is under-crimping.
Twist to the left (out of the
micrometer) if the machine is
over-crimping.
NOTE:
Each complete rotation of the stem foot is approximately .027” change in crimp
diameter. For example: If the Kurt Hydraulics crimp specification is .885” and
the observed crimp diameter is .872”, the stem foot needs to be turned
approximately one half turn to the left (out of the micrometer) for a looser
crimp.
3.
Re-tighten the jam nut to secure the position of the stem foot.
4.
Make another crimp to measure and verify that the average crimp diameter is within the
Kurt Hydraulics crimp specification. If it is, the crimper is calibrated. If not, repeat steps
1-5 until a crimp within tolerance is obtained.
5.
Contact Kurt Hydraulics for further assistance, if necessary.
