AEROSHELL 33 GREASE 14 OZ TUBE

Packaged Items
SingleCase of 30

Overview

Developed with the purpose of satisfying almost all airframe lubrication requirements with a single grease. Its enhanced corrosion resistance and load-carrying capacity reduces wear and tear and can lead to extension of re-greasing intervals and reduction in maintenance costs. Replacing several greases with a single grease avoids the risk of misapplication and also reduces stock inventory, again providing cost savings. Useful temperature range is -73°C to +121°C.

Applications

For many years aircraft operators have been seeking to rationalize 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.

Owing to the wide range of operating temperatures, loads and other environmental conditions required for various aircraft components, several different types of grease with different desirable properties are used during routine lubrication of aircraft components. Boeing, in developing their BMS 3-33 specification, took account of the properties of the different grease types used on aircraft and wrote a specification for a grease which would provide improved performance and which could be used in the widest possible range of grease applications. That performance level has largely been adopted as the SAE AMS 3052 specification, which is in turn the basis for the Airbus AIMS 09-06-002 specification.

AeroShell Grease 33 is approved to BMS 3-33B and offers the improved performance properties required by this specification and the other specifications mentioned above.

AeroShell Grease 33 can be used for routine lubrication on Boeing aircraft where MIL-PRF-23827C or BMS 3-24 is specified. AeroShell Grease 33 can also be used in some applications on Boeing aircraft which require use of MIL-G-21164. Other applications on Boeing aircraft which require use of MIL-G-21164 and other greases are being reviewed and in due course Boeing will issue details of the full range of applications. For the current status, refer to the latest issue of Boeing Service Letter “BMS 3-33 General Purpose Aircraft Grease”.

AeroShell Grease 33 can be used for routine lubrication in applications where MIL-PRF-23827C is specified on aircraft manufactured by McDonnell Douglas, Airbus, BAe Regional Aircraft, Canadair, Lockheed, Embraer, Fokker and Gulfstream (except for wheel bearings, applications above 121°C and sliding applications requiring molybdenum disulphide).

Other aircraft manufacturers are evaluating AeroShell Grease 33 with the aim of approving it for use on their aircraft. Operators should regularly check with these manufacturers for the latest status.

Use of AeroShell Grease 33 can provide operators with the following benefits:

  • Reduced inventories
  • Easier maintainability (one major grease for most applications)
  • Reduced maintenance labour costs
  • Less chance of product mis-application
AeroShell Grease 33 contains a synthetic oil and must not be used with incompatible seal materials. Refer to the General Notes at the front of this section for further information.

Reviews

Great all-around airframe grease. Looks blue/green to my partially color-blind eyes, but still stands out from the dirty old brown grease its pushing out of the joints at zerks. Spreads easily with a brush/finger as well.

this is the best grease by far for use as a wheel bearing lube where high temp failure has been a problem in the past.

I use the Aeroshell #6 to service my Hartzell propellers every 50 hours with six pumps (1 oz.) per blade and I have never had a prop issue--this is my 51st year of flying.
