21087716 Retainer | Genuine Volvo Penta Part

🔧 Product Description

Brand-new genuine Volvo Penta double-head retaining strap used in the factory air-compressor and auxiliary-system installation on the TAD1643VE-B. The moulded retainer secures paired hoses or cables at a fixed spacing so vibration cannot pull them into the compressor drive, hot surfaces or adjoining hydraulic components.

🔌 Function

Holds two adjoining hoses or cables at the designed spacing and prevents uncontrolled movement, abrasion and vibration fatigue.

⚠️ Common Signs of Failure

• Hoses or cables rubbing against the compressor or bracket
• Retainer split, hardened or no longer gripping both lines
• Excessive line movement at idle
• Chafing marks or flattened hose sections
• Missing retainer allowing the lines to contact hot or rotating parts

🛠️ 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
