Cleaning and greasing the shrink disk
Note
Only dirty shrink disks must be disassembled and cleaned.
•
Check all parts for any damage.
WARNING
Serious injury
Risk of injury through single parts being slung out (e.g. tensioning bolts).
Damaged parts must be replaced with new ones.
The use of damaged parts is not permitted.
Only the complete shrink disks supplied by the manufacturer may be used.
Combining components from different shrink disks is not permitted.
•
Thoroughly clean all parts.
CAUTION
Risk of injury through chemical substances
Observe manufacturer's instructions for handling lubricants and solvents.
Wear suitable protective clothing.

The conical surfaces of the inner and outer rings (positions 3 and 4, see figure 13) must be free of grease
and oil.
Contaminated solvents and dirty cloths as well as cleaning agents containing oil (such as paraffin or
turpentine) are not suitable for removing grease.

A thin layer of lubricant must be applied evenly to the conical surfaces of the inner and outer rings
(positions 3 and 4, see figure 13).
•
Provide the tensioning bolts (position 5, see figure 13) on the contact surface and on the thread with
lubricant.
Use a solid lubricant paste with a high MoS
slide during fitting work and which shows the following characteristics:
─ Friction coefficient "μ" = 0.04
─ Resistant to pressure up to a maximum pressure of 300 N/mm
─ Ageingresistant
based molybdenum disulphide content which will not
