21663772 Support | Genuine Volvo Penta Part

🔧 Product Description

A structural support used in the EDC4 cooling system of Volvo Penta TAD732GE and TAD733GE generating-set engines.

🚤 Compatibility

Typically suits:

• Volvo Penta TAD732GE EDC4
• Volvo Penta TAD733GE EDC4

• Engine Family: TAD

⚙️ Key Features

• EDC4 cooling-system application
• Supports coolant and charge-air pipework
• Engine-duty vibration-resistant construction

🔌 Function

The support holds cooling and charge-air components in the required position and prevents vibration from stressing their connections.

⚠️ Common Signs of Failure

• Support cracked or bent
• Pipework moving or rubbing
• Fretting at fasteners
• Hose or clamp failure from misalignment
• Repeated mounting-bolt loosening

🛠️ Service Notes

• Offer the support up and get both ends aligned with the fasteners finger-tight before tightening anything down — forcing a bracket into place leaves the component and the support permanently in strain
• Check the mating faces are clean and flat and that the support sits fully home without packing or shimming unless the workshop manual for your engine calls for it
• Inspect the old support, and the casting or panel it bolts to, for cracks around the bolt holes and elongated or worn holes; a support that has been working loose has usually damaged its seat as well
• Renew any locking fasteners and tighten to the figure given in the manual for your engine, then support the component so it is not left hanging on hoses, wiring or pipework
• Recheck the fasteners after the first period of running, and confirm the supported item still has clearance from moving parts and hot surfaces
