Nominal Crimp Diameter Measurement - Eaton ET1187 Operator's Manual

Establishing Crimp Settings - Micrometer Dial
The micrometer section on the color
coded collar can be used to crimp other
products not captured on the 3 primary
color coded collar settings, based on
crimp target settings available in Pow-
erSource.
The crimp adjustment knob above the
pusher determines the target crimp
diameter for each combination of hose,
fitting, and die cage.
The numbers on the color coded col-
lar and crimp adjustment knob are for
selecting target settings and not crimp
diameters.
Settings between 000 and 400 can be
achieved with this crimp machine.

Nominal Crimp Diameter Measurement

Measuring crimp diameters should be
part of the normal hose assembly pro-
cedure. To insure a proper crimp diam-
eter reading, follow these steps:
1. Measure the diameter in the middle
of the crimped portion of the hose
end.
2. Place the caliper in a position to
allow for a measurement across the
pressed (flat) portion of the crimp.
3. See crimp diameters in Crimp
Specifications.
6 EATON ET1187 Operating Instructions E-EQCR-11001-E1
Consult the target setting chart in
PowerSource for the ET1187 crimp
machine for the initial setting.
There are 25 marks on the crimp
adjustment knob (0-24), and 16 marks
on the barrel (025-400 by 025 incre-
ments).
When the crimp adjustment knob is
rotated to where the knob is lined up
with the 000 line on the collar, and the
"0" mark on the knob is lined up as
shown in figure 10. The crimper target
setting is set at 000.
When the crimp adjustment knob is
rotated to the top most position on the
crimper, and the "0" mark is located as
shown in Figure 11, the machine setting
is 400.

Each complete upward rotation of the
adjustment knob increases the target
setting by 025; each mark around the
dial corresponds to a 001 change in
target setting.
For example, to achieve a target setting
of 050, the adjustment knob is rotated
until the top of it corresponds to the 050
mark on the collar, and the 0 mark on
the dial is lined up with the center, verti-
cal mark on the collar.
One more full upward rotation of the
crimp adjustment knob would result in
a target setting of 075. If the desired
target setting is 065, the dial would
instead be rotated upward 15 "marks"
on the dial as shown in figure 12, or
approximately 2/3 of a turn, past the
050 target setting.
