Aircraft maintenance demands meticulous attention to detail, and the selection of lubricating grease is paramount. While traditional clay-based greases have served the aviation industry for decades, advanced lithium complex greases now offer superior performance and simplified maintenance procedures. This article examines the benefits of AeroShell Grease 33 lithium complex grease and provides a comprehensive guide for upgrading your aircraft lubrication system.

Lithium Complex Grease: Comprehensive Performance Advantages

Compared to conventional greases, lithium complex formulations deliver exceptional performance that makes them increasingly popular in aviation applications. Key advantages include:

• Superior mechanical stability: Lithium complex grease maintains excellent adhesion to lubricated components, resisting displacement and ensuring long-lasting protection.
• Enhanced water resistance: With outstanding anti-washout properties, these greases perform reliably in wet conditions, protecting components from corrosion and wear.
• Extended service life: Improved shear stability and oxidation resistance allow lithium complex greases to maintain performance across temperature extremes, reducing maintenance frequency.
• Broad compatibility: The lithium complex thickener works effectively with various high-performance additives to deliver superior oxidation protection, corrosion resistance, wear prevention, and extreme-pressure capabilities.
• Simplified inventory management: Standardizing on lithium complex grease reduces the risk of incompatible lubricant mixing while minimizing the variety of greases needed in inventory.

AeroShell Grease 33: The Benchmark in Lithium Complex Aviation Grease

AeroShell Grease 33 represents a high-performance lithium complex grease specifically engineered for aircraft applications. Its notable characteristics include:

• Exceptional water washout resistance compared to AeroShell Grease 7, providing better component protection and enhanced safety
• Superior load-carrying capacity for improved wear protection and extended component life
• Compliance with stringent industry standards as the first grease to meet the original BMS 3-33 specification
• Selection as factory-fill grease by numerous leading aircraft manufacturers
• Potential maintenance cost reductions through multi-application use

Transitioning from Clay-Based Greases

Clay thickeners, such as the Microgel® used in AeroShell Grease 7, have served aircraft effectively since the mid-1960s due to their water resistance and high-temperature performance. While these greases remain serviceable, many manufacturers now prefer advanced lithium complex alternatives for their superior characteristics.

Implementation Considerations

Aircraft and lubricant manufacturers recommend against mixing different grease types due to potential compatibility issues. The conversion process requires:

1. Complete removal of old grease from bearing surfaces and internal cavities before applying new grease
2. When complete removal isn't feasible, flushing the system with new grease until only the fresh product remains

Conclusion

Upgrading to AeroShell Grease 33 lithium complex grease represents a strategic improvement in aircraft maintenance practices. This advanced lubricant delivers superior performance, extends component life, and simplifies maintenance procedures while potentially reducing operational costs. For operators seeking high-performance, reliable aviation grease, AeroShell Grease 33 offers a compelling solution.
