Rotate the setting nut by the requested number of
notches (see step 1 and 2 in illustration 15) by means of
a hook spanner (see table 8).
Illustration 16
With torque setting please note the setting
diagrammes of the respective sizes (see
chapter 5.3).
Remove the torque value from the label (see step 3 in
illustration 15).
Mark the coupling with the new torque pre-set (see
step 1 in illustration 16).
Remove the reference mark from the setting nut (see
step 2 in illustration 16).
Remove the cap screw from the setting nut.
Coat the cap screw with Loctite (average strength).
Afterwards screw in the cap screw and tighten at the
tightening torque T
A
specified in table 7.
Illustration 17
All screw connections must be secured against working loose additionally,
e. g. conglutinating with Loctite (average strength).

!
Please bear in mind that setting the torque beyond the torque range (see chapter 1) may
result in misoperation and damage of the coupling.
In order to ensure an optimum torque setting, SYNTEX
®
-NC should be inspected after initial
disengagement processes and reset, if necessary.
If SYNTEX
®
-NC was pre-set only or set to the requested torque as per these
operating/assembly instructions, the torque should be considered as a reference value only.
For accurate torque setting we would recommend to inspect the torque by means of a
suitable measuring system and reset, if necessary.
We basically recommend to perform torque setting on KTR's test benches in order to
ensure the optimum accuracy of torque setting.
