21340868 Flange Screw | Genuine Volvo Penta Part

🔧 Product Description

Genuine Volvo Penta high-strength flywheel retaining screw used on D9A2A engines. The screw clamps the flywheel to the crankshaft flange and must be tightened in the specified sequence and to the correct torque/angle because flywheel security directly affects starter engagement, torsional balance and driven-equipment alignment.

🔌 Function

Clamps the flywheel to the crankshaft flange, holding the joint tight enough that the flywheel cannot move or fret under load.

⚠️ Common Signs of Failure

• Knocking or rumble from the flywheel end under load
• Starter grinding or jumping out as ring-gear alignment moves
• Rust-coloured fretting dust around the flywheel flange
• Screw found stretched, necked at the thread, or with a fretted head face
• Crankshaft flange or flywheel found polished by fretting on strip-down

🛠️ Service Notes

• Flywheel screws are tightened in a set sequence to a torque-angle procedure - work to the workshop instruction, not to a torque figure alone
• Clean and dry the flange faces and threads before fitting, and renew rather than reuse where the procedure calls the screw single-use
