Cleaning and greasing the shrink disk
Only dirty shrink disks must be disassembled and cleaned.
•
Check all parts for any damage.
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.
Do not use contaminated solvents or dirty cloths nor cleaning agents containing oil
(such as paraffin or turpentine) for removing grease.
•
The conical surfaces of the inner and outer rings (3 and 4, see figure 19) must be free of grease and
oil.
─ A thin layer of lubricant must be applied evenly to the conical surfaces of the inner and outer rings
(3 and 4, see figure 19).
─ Provide the tensioning bolts (5, see figure 19) on the contact surface and on the thread with
lubricant.
─ Use a solid lubricant paste with a
high MoS
2
based molybdenum disulphide content
which will
not 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
2
─ ageingresistant
