For Shrink Fitted Assemblies the adhesive should becoated onto the pin, the collar should then be heated tocreate sufficient clearance for free assembly.6. Parts should not be disturbed until sufficient handlingstrength is achieved.For Disassembly1. Apply localized heat to the assembly to approximately250 °C. Disassemble while hot.For Cleanup1. Cured product can be removed with a combination ofsoaking in a Loctite solvent and mechanical abrasionsuch as a wire brush.Loctite Material Specification LMSLMS dated September-1, 1995.
