Input hub with fitted key
Undo the threaded pin (9) used to radially secure
the fitted key.
Use a removing device, e.g. three-arm puller, to
pull off the drive hub against the motor shaft
without heating the hub:
Alternatively, there are two threads (13) at the
front of the input hub that can be used to fasten
the counter-holder of the removing device. Press
off against a removing aid (12) on the cover (8).
Keep turning the puller until the cover is at the
motor shaft.
The cover plate may cause the input hub to jam
when being pulled off.
Position cover plate (8) centrally on motor
shaft.
Replace the end disk 28 DIN 470 after disassembly.
Clean before installing and coat the sealing edge with
liquid seal. Visually check the shaft seal and O-ring
and fit new ones if necessary.
