Disassembling the FLUDEX coupling

For part designations, see section 11.
Risk of burns after switching off.
Allow the FLUDEX coupling to cool down sufficiently before beginning work.

10.5.1 Disassembling the sizes 222 to 342

After moving the motor away the retaining screw (141) and locking plate (140) are first removed and then
the locking ring (124) demounted. When pulling off the FLUDEX coupling, care must be taken that
pulling­off forces are conducted only through the steel hollow shaft (106).
The coupling is best pulled off with the aid of a special detaching device as shown in figure 12. The spindle
with the pulling­off nut is inserted so that the collar (D) of the pulling­off nut is located behind the recess
for the locking ring (124) (Fig. 13). To prevent the spindle seizing, the pressure surface and the thread must
be treated with a lubricant (e.g. Molykote).

The locking ring (124) is refitted and the spindle turned forward as far as the shaft stub end face and into
the safety countersink in the centring thread. Care must be taken that the nut collar rests evenly against
the locking ring.
To prevent flexing and canting, the spindle should be supported as shown.

The coupling is pulled off the shaft stub by turning the spindle further into the forcing­off thread and bracing
the nut. It is recommended that a hydraulic spindle be used, depending on the size of the coupling.
