WACKER Group 0007587, Repair Manual

Use Of Threadlockers and Sealants

Threadlocking adhesives and sealants are specified throughout this manual and should be used where indicated.
Threadlocking compounds normally break down at temperatures above 350° F (175° C).  If a screw or bolt is hard
to remove, heat it using a small propane torch to break down sealant.  When applying sealants, follow instructions
on container. The sealants listed below are recommended for use on WACKER equipment.
