NOTE: DO NOT measure on top of part number
stamps or ridges.
1. Measure crimp diameter.
• Using Gates calipers (Product No. 7369-1320/
Part No. 78217), measure halfway between
ridges. (Fig. 1) To be sure crimp diameter is being
properly measured, mark a crimp flat. Beginning
with that flat, count 9 flats to get the diameter. Be
sure caliper fingers DO NOT touch ridges or part
number stamps.
• Measure halfway between the ends of the
crimped portion of the ferrule. (Fig. 2)
2. Check crimp diameter.
• The measured crimp diameter must be within
0.010" of the published crimp diameter.
• Should the actual crimp diameter not be within
specified crimp tolerance, the assembly MUST
be discarded.
MEASURING AND ADJUSTING CRIMP DIAMETERS
WWAARRNNIINNGG
::
Protect the safety of people using your assemblies!
Your measured crimp diameters MUST be in tolerance
range as listed in the Gates Crimp Data Manual.

3. Adjust the crimp diameter (if necessary).
• If crimp diameter is not within specified crimp
tolerance, an adjustment to the crimp setting
needs to be made.
• To obtain a smaller crimp diameter, change dial
vernier setting to a smaller number.
• To get a larger crimp diameter, change dial
vernier setting to a larger number. Changing the
dial vernier number by approximately .02 will
change crimp diameter .001".
• After the correct diameter is achieved, record this
new setting in your crimp data manual for future
reference.
4. Multiple crimps.
• When crimping multiple assemblies, check every
tenth crimp to ensure diameter is within accept
able range (± 0.010").
• Discard those outside the specified tolerance.
