21112999 Flange | Genuine Volvo Penta Part

🔧 Product Description

A genuine Volvo Penta flange engineered for the flywheel assembly on TAD650VE/TAD660VE and related D7 engines. This component is a machined flange mounted with the flywheel to locate or connect the driven equipment. Correct selection requires the complete Volvo Penta product number and serial number because adjoining components, mounting arrangements and production revisions can change within the same engine or transmission family.

⚙️ Key Features

• Machined face maintains concentricity with the flywheel
• Pilot diameter locates the attached coupling or driven component
• Bolt pattern transfers cyclic engine torque
• Controlled thickness maintains axial spacing
• Balanced assembly is required after flywheel service

🔌 Function

Provides the accurately centred mounting and torque-transfer interface on the flywheel assembly for the connected transmission or driven equipment.

⚠️ Common Signs of Failure

• Fretting around the pilot or bolt holes
• Runout causing vibration
• Cracks from loose fasteners
• Corrosion preventing accurate coupling seating
• Damaged mounting face or thread

🛠️ Service Notes

• Clean both mating faces back to clean metal and check them for flatness and for burrs or old gasket left in the sealing area; a face pulled up around a stud hole will not seal however hard it is tightened
• Always fit a new gasket, seal or O-ring where the joint uses one, and only use a jointing compound if the workshop manual for your engine calls for one at that joint
• Draw the fasteners up evenly in stages, working across the flange rather than round it, and finish to the tightening sequence and figures given for your engine
• Inspect studs, nuts and threads while the joint is apart and renew anything corroded, stretched or seized — exhaust-side fasteners rarely come out twice
• Re-check the joint for leaks once the engine has been up to working temperature and cooled again
