SCOPE The material defined by this specification is a grease consisting of synthetic ester, non-soap thickener and other additives to give the desired characteristics. 2. APPLICATION This specification was released original
3、ly for grease used to prevent corrosion in fuel filler cap locks. It is also suitable for corrosion protection in other lock mechanisms and where noise damping is required on interior and exterior systems. The material has good resistance to water, fuel and hydrocarbon solvent washout. Use of this m
4、aterial with polymers other than polyoxymethylene (acetal) or polyamide is not recommended. A: This specification was released originally for grease used to prevent corrosion in fuel filler cap locks. It is also suitable for corrosion protection in other lock mechanisms. The validated material is ma
5、rketed by Ford Customer Service Division in Europe as part of a Squeak & Rattle Repair Kit, Part No. 5U7J 000A94 AA. Operating temperature range -40 C to 200 C. A2: This specification was released originally for grease used to lubricated and prevent corrosion in window regulators, latches, catches a
6、nd hinges. It is also suitable for lubrication and corrosion protection in similar mechanisms. Operating temperature range -40 C to 200 C (-15 C to 200 C dynamic). 3.
