21344756 Flange Screw | Genuine Volvo Penta Part

🔧 Product Description

Genuine Volvo Penta flange screw used in specified TAD16 lubrication-system hardware and in related TWD16 cooling/fan-frame installations. Because the same hardware reference appears in more than one heavy-engine assembly, fitment must be controlled by the exact schematic position and required screw dimensions.

🚤 Compatibility

• Engine Family: TAD, D, TWD

Full model list at the end of this description.

⚙️ Key Features

• Flange screw in specified TAD16 lubrication-system hardware and related TWD16 cooling and fan-frame installations
• 0.041 kg

🔌 Function

Clamps its assigned joint in the lubrication-system or cooling and fan-frame hardware, providing the specified clamp load at that position.

⚠️ Common Signs of Failure

• Oil or coolant weeping at the joint it clamps
• Component moving or a fan frame flexing where it should be solid
• Repeated loosening at the same fastening
• Screw found stretched, or the head face found fretted
• Mating faces found fretted where clamp load has been lost

🛠️ Service Notes

• The same hardware reference appears in more than one heavy-engine assembly, so control fitment by the illustrated position and required dimensions rather than the title
• Flange screw 21344774 is published at the same 0.041 kg but does a different job - weight will not tell the two apart
