• Used in a two-retainer arrangement in the applicable schematic

• Inspect all lifting hardware before using the engine lifting points

🔌 Function

Retains the specified lifting or anchorage component so the engine lifting hardware remains correctly located and supported.

⚠️ Common Signs of Failure

• The retainer is bent, cracked or corroded
• The lifting hardware develops movement or fretting
• Mounting holes or locking features are worn
• The associated bracket no longer aligns correctly
• Replacement is required after overload or lifting-point damage

🛠️ Service Notes

• Fit the retainer clean and dry unless the manual calls for lubricant, and make sure it is fully home in its groove or against its seat before the assembly is loaded
• Renew rather than reuse a retainer that has been removed — once a spring clip or ring has been spread it loses tension and can release in service
• Use the correct pliers or fitting tool; opening a retainer further than it needs to go, or prising it with a screwdriver, distorts it permanently
• Check the groove or landing face for wear, burrs and scoring, and dress or renew the mating part if the retainer will no longer seat squarely
• Where the retainer holds a rotating or spring-loaded part, confirm by hand that the assembly is captive and has the free movement the manual specifies before closing up
