Disassembling the FLUDEX coupling

For part designations, see section 11.
FLUDEX couplings should as far as possible be repaired at the manufacturer's works.
Before disassembly the housing parts must be marked on the flange in their positions relative to one
another.
The housing parts of the coupling, the shell (101) and the cover (102) are joined at the outer flange by
screws (130) and nuts (131). For disassembly these screws must first be removed.
Fig. 15: Disassembling the FLUDEX coupling
To pull off the shell and cover, a pressure spindle with a bridge and pulling screws must be applied as
shown in figure 15. The pressure acts on the end face of the steel hollow shaft. The pulling screws are
inserted in the flange threads of the shell or cover. After the shell and cover are pulled off, the internal parts
(rolling bearings, shaft-sealing rings, etc.) will be accessible. The sealing elements should be replaced
every time the coupling is disassembled.

Reassembling the FLUDEX coupling

Reassembly is carried out in the reverse order (note part marking). The O­ring (114) must be lightly
greased to assist assembly. The shaft­sealing rings (111; 132) are fitted with a grease filling between the
dust and sealing lips. Likewise, on the design with an additional Fey laminar ring seal the space between
the shaft­sealing ring and the plates and the plate­mounting groove in the shaft must be filled with grease.
After the old sealing thread has been removed and the sealing surfaces have been cleaned, a fresh sealing
thread must be applied to places on the flange which have been sealed with sealing thread. The sealing
thread must be placed in a circular form at the place provided on the sealing surface and with the thread
ends crossed over. The sealing surface must be undamaged and may be lightly greased for better
positioning of the sealing thread.
For tightening torques for screw connections, see section 6, item 6.6.

Refitting the FLUDEX coupling

For re­fitting, the instructions in section 6, "Fitting", and section 7, "Start­up", must be carefully observed.
