SCOPE The material defined by this specification is a NLGI Grade 1 grease containing mineral oil, lithium soap, and zinc oxide, modified with a polymer agent. The
3、 lubricant operating temperature range is -26 to 149 C. 2. APPLICATION This specification was released originally for grease used to lubricate, waterproof and provide corrosion resistance for electrical connectors and switch components, consisting of brass, copper, copper beryllium, and silver. Othe
4、r applications include the transmission pilot bearing before assembly to the engine to prevent seizing and facilitate service. 3.

11、2 INTERFACE COMPATIBILITY 4.12.1 Chemical Attack to Painted Surfaces (FLTM BJ 126-01). Note: Not tested for initial application of this grease. Grease must be tested for chemical attack to painted surfaces for applications that come in contact with paint surfaces, ex. E-coat and powder coat. 4.12.2
12、Resistance to Stress Cracking No cracking or crazing (FLTM BO 127-03) Note: Not tested for initial application of this grease. Grease must be tested for resistance to stress cracking when used for additional applications that come in contact with polymers such as PC, ABS, PC+ABS, ASA or acrylic. 4.1
