Both screw plugs (component 7) have to be removed.
One hole serves as a filler hole, the other one as venting hole.
With each reassembly of the coupling we recommend to replace the flat gasket (component
5) and the dowel screws (component 3) as well as nuts (component 4).
!
In order to ensure a long service life of the coupling and avoid damages on the coupling,
make sure to adhere to the quantities of grease specified for the different coupling sides.
Grease which has flown over has to be collected completely and disposed of according to
the regulations that apply.
The failures specified below can lead to a use of the
GEARex

coupling other than intended. In addition to the
specifications given in these operating/assembly instructions make sure to avoid such failures.
The errors listed can only be clues to search for the failures. When searching for the failure the adjacent
components must generally be considered.
If used other than intended the coupling can become a source of ignition.
EU directive 2014/34/EU requires special care by the manufacturer and the user.
General failures with use other than intended:
•
Important data for the coupling selection were not forwarded.
•
The calculation of the shaft-hub-connection was not considered.
•
Coupling components with damage occurred during transport are assembled.
•
If the heated hubs are assembled, the permissible temperature is exceeded.
•
If mounted in heated condition, the O-rings are heated excessively/damaged.
•
The clearance of the components to be assembled is not coordinated with one another.
•
Tightening torques have been fallen below/exceeded.
•
Components are mixed up by mistake/assembled incorrectly.
•
No original
KTR
components (purchased parts) are used.
•
Old/already worn out coupling components stored for too long are used.
•
Maintenance intervals are not observed.
•
No lubricants recommended by
KTR
are used.
•
Operating temperatures are exceeded.
•
Axial fastening of hubs is not available or working loose.
•
Insufficient or inappropriate lubrication.
•
Operating conditions were modified inappropriately.
