AeroShell Grease 33 lubricates all but 9 of 359 grease application points on a Boeing 737!! AeroShell Grease 33 is a synthetic universal airframe grease composed of a lithium complex thickened synthetic base oil.
For many years aircraft operators have been seeking to rationalise the greases used on aircraft and to reduce the number of different greases in their inventories. Recently Boeing began research on a new, general purpose, corrosion-inhibiting grease. The aim was for a non-clay based grease that would provide longer life for components and mechanisms and possess improved wear and corrosion resistance. This led to the introduction of the new Boeing Specification BMS 3-33 and AeroShell Grease 33 is approved to BMS 3-33A and offers.
