GENERAL INSTRUCTIONS FOR SWINGING ANCHOR SYSTEMS

•
Fit the gear unit on to the machine shaft or vice versa (excessive axial force shouldn't be necessary); there should be no
interference when assembling, so make sure the shaft and gear unit are properly aligned..
•
Using a torque wrench, tighten all the bolts gradually working your way round them (sequentially, not switching from side to
side) until they have all been tightened to the torque value “Ma” shown in Table 1.
•
Set the torque wrench to 3 - 5% above the setting given in table N° 1, then tighten the coupling bolts to the new setting.
Ma (Nm.) = bolt torque
•
Set the torque wrench again to setting “Ma” shown in Table 1 then re-check the torque on the coupling bolts, taking care
not to tighten them any further. If this happens, repeat the torque sequence.
•
When the coupling has been correctly fitted, visually inspect the assembly to make sure that the front surfaces of the inner
and outer rings are on the same plane (see Fig. 4 pto. S).
DISASSEMBLING THE COUPLING.
•
Gradually loosen the anchor bolts, working your way round in a circle. Loosen each bolt by just a quarter of a turn to start
with to avoid bending and seizing.
•
If the coupling rings don't spring apart naturally after the bolts have been unscrewed, transfer some of the bolts (two bolts
at 180° or 4 at 90°) into the internal ring extraction holes (see Fig. 5), giving them no more than one turn a time to tighten
them, alternating if there are 2 bolts and in a circle if there are 4.

on account of the high axial force, if the bolts are unscrewed completely in one or two turns, the two rings in the coupling may
spring violently apart, putting the operators in danger.

NOTE:
We recommend you use 10.9 or 12.9 class bolts when the application is subject to strong jolts, frequent stops, changes
of direction or when 70% of the maximum permitted torque is exceeded.
CAUTION
