Removing the expansion mechanism
– Prerequisite: Spool hub is removed.
Remove screw [294E] from key [294D] and remove

fitting key.
Pull off the expansion mechanism from the shaft.

Disassemble the expansion mechanism as necessary:
Remove the release button [294B]

Loosen the 3 setscrews [294C] on front

cone [294A]. Remove cone and spring.
Soften the adhesive bond at the rear cone [294F]

with a hot air blower, then remove the cone.
Assembly of expanding mandrel
Adhesive bonds and screw retention:
Clean the contact areas of any adhesive bonds that

were freed. Use Loctite 480 for metal-synthetic ad-
hesive bonds
Clean all threads that were secured with threadlock.

Secure the screw connections with Loctite 243.
Follow the adhesive/threadlock manufacturer's inst-

ructions for use.
Installing the expansion mechanism:
Grease the hollow shaft inside and out.

Push the expansion mechanism onto the carrier

shaft and fit the key.
Fix the front cone [295C] in the correct mounting posi-
tion (only necessary if expansion mechanism was dis-
assembled):
– The grooves in the two cones must be exactly
aligned.
Align the cone with the adjust gauge [295A] and

screw it flush to the front end of the hollow shaft.
While doing so, do not tighten the setscrews [295B]
too tightly. The hollow shaft must be loose enough
to move on the carrier shaft.
If no adjust gauge is available, the cone can also be
aligned with one of the spool hub segments [296].
However, this method is of limited accuracy.
Grease the cones lightly.

Install the spool hub.

Check the expansion mechanism is functioning pro-

perly, adjust if necessary (see following page).
