Directions For Use:
For Assembly 1. For best results, clean all surfaces (external and internal) with a LOCTITE® cleaning solvent and allow to dry
2. If the material is an inactive metal or the cure speed is too slow, spray with LOCTITE® SF 7471™ or LOCTITE® SF 7649™ and allow to dry
3. For Slip Fitted Assemblies, apply adhesive around the leading edge of the pin and the inside of the collar and use a rotating motion during assembly to ensure good coverage
4. For Press Fitted Assemblies, apply adhesive thoroughly to both bond surfaces and assemble at high press on rates
5. For Shrink Fitted Assemblies the adhesive should be coated onto the pin, the collar should then be heated to create sufficient clearance for free assembly
6. Parts should not be disturbed until sufficient handling strength is achieved
LOCTITE®660™ is designed for the bonding of cylindrical fitting parts, particularly where bond gaps can approach 0.50mm (0.02 in.)The product cures when confined in the absenceof air between close fitting metal surfaces and prevents loosening and leakage from shock and vibrationThis product possesses excellent gap cure characteristicsTypical applications include restoring correct fits on worn shafts, spun bearings, and damaged keyways.
