Assembly
Revision: 07 2022-D026817 en-13

Tighten the threaded pin (H) of the clamping hub (C).

For screw sizes and prescribed tightening torques, see Chapter 9.1 "Specifications for
mounting onto a motor", Table "Tbl-14".

Press the enclosed stopper plugs up to their stop into the mounting bores of the
adapter plate (B).
5.4 Components mounted on the output side
Clamping forces during assembly can damage the gearhead.

Mount the mounting parts onto the output shaft without using force.

Never attempt to assemble by force or hammering!

Only use suitable tools and devices for assembly.

Make sure not to exceed the maximum permissible static axial forces on
the output bearing (see Table "Tbl-8") when pulling or shrink-fitting a
mounting part onto the output shaft.
