4.9.3.3 Pulling off the shrink disk
Procedure
1. Successively release the tightening bolts ⑥ one after the other through a ¼ turn each time
using a wrench. Do not completely remove the bolts.
2. Pull the shrink disk off the hollow shaft.
Sizes 79 - 189:

bolts and insert them into neighboring forcing threads.

4.9.3.4 Cleaning and lubricating shrink disks
Soiled shrink disks must be cleaned and regreased prior to fitting.
Shrink disks that have been released need not be disassembled and regreased before being
retensioned.
Procedure
1. Only grease the inner friction surfaces of the shrink disks. To do this, use a solid lubricant
with a friction coefficient of μ = 0.04.
2. Use a paste containing MoS
2 to grease the bolts, applying the paste to the thread and
underneath the head.
Clean the shrink disk.
