Operating instructions 01/2019
6.7.1
Fitting
Before fitting, the halfshells must be removed from the hubs and the holes carefully cleaned and
degreased using a suitable degreasing agent.
Observe the manufacturer’s instructions for handling the solvent.
Do not interchange halfshells.
Check that the number markings (markingpunch number) at the side of the hub core
are identical (see Fig. 14).
Place the clamping hubs on the shaft ends. The tension screws in the halfshell must first be evenly
screwed up only handtight.
Ensure the halfshells are evenly seated. Check the gap size is even and, if necessary,
adjust.
Then, using a torque wrench, tighten the tension screws alternately in at least 3 passes (see table 4).
First pass:
Tighten the clamping bolts to
30 %
of the tightening torque (see table 4).
Second pass:
Tighten the clamping bolts to
60 %
of the tightening torque (see table 4).
Third pass:
Tighten the clamping bolts to
100 %
of the tightening torque (see table 4).

Demounting
Demounting is done in reverse order of fitting. Here the tension screws must be undone alternately in at
least 2 to 3 passes.
Risk of injury from falling coupling parts.
Secure all coupling parts before undoing the clamping bolts.
