Product Specification

AeroShell Grease 33-Fuselage, Good Low Temperature Performance

Synthetic grease for aircraft

AeroShell Grease 33 is a synthetic universal airframe grease composed of a lithium complex thickened synthetic base oil with corrosion and oxidation inhibitors and load carrying additives.The useful operating temperature range is –730C to +1210C.

Main Applications

For many years aircraft operators have been seeking torationalise the greases used on aircraft and to reduce thenumber of different greases in their inventories. RecentlyBoeing began research on a new, general purpose,corrosion-inhibiting grease. The aim was for a non-claybased grease that would provide longer life for componentsand mechanisms and possess improved wear andcorrosion resistance. This led to the introduction of the newBoeing Specification BMS 3-33.

Owing to the wide range of operating temperatures, loadsand other environmental conditions required for variousaircraft components, several different types of grease withdifferent desirable properties are used during routinelubrication of aircraft components. Boeing, in developingtheir BMS 3-33 specification, took account of the propertiesof the different grease types used on aircraft and wrote aspecification for a grease which would provide improvedperformance and which could be used in the widestpossible range of grease applications.

AeroShell Grease 33 is approved to BMS 3-33C and offersthe improved performance properties required by thisspecification.

AeroShell Grease 33 can be used for routine lubrication onBoeing aircraft where MIL-PRF-23827C or BMS 3-24 isspecified.

AeroShell Grease 33 can also be used in someapplications on Boeing aircraft which require use of MIL-G21164.

Other applications on Boeing aircraft which requireuse of MIL-G-21164 and other greases are being reviewedand in due course Boeing will issue details of the full rangeof applications. For the current status, refer to the latestissue of Boeing Service Letter "BMS 3-33C GeneralPurpose Aircraft Grease".

AeroShell Grease 33 can be used for routine lubrication inapplications where MIL-PRF-23827C is specified on aircraft manufactured by McDonnell Douglas, Airbus, BAe RegionalAircraft, Canadair, Lockheed, Embraer, Fokker andGulfstream (except for wheel bearings, applications above1210C and sliding applications requiring molybdenumdisulphide).·Other aircraft manufacturers are evaluating AeroShellGrease 33 with the aim of approving it for use on theiraircraft. Operators should regularly check with thesemanufacturers for the latest status.·Use of AeroShell Grease 33 can provide operators with thefollowing benefits:·Reduced inventories;Reduced maintenance labour costs;Less chance of product mis-application.

FAQ

Q:What is the features of the Aeroshell 33?

A:1.Reduced costs through superior protection, longer grease life and simplified maintenance and inventories

2.Longer component life from superior corrosion and wear protection

3.Longer grease life through excellent mechanical stability and controlled oil separation

4.Peace of mind from a grease with more in-service hours than any grease in its class

Q:What is the advantage of the AeroShell Grease 33 in terms of aircraft maintenance?

A:Following a testing period by Boeing, AeroShell Grease 33 was the only product to meet all the requirements of the original BMS 3-33 specification. It can be used on all but 9 of the 359 grease application points on a Boeing 737. This greatly simplifies the maintenance of this and many other aircraft and enhances safety by reducing the risk of product misapplication
