# 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.

## 🚤 Compatibility

-   **Engine Family:** D, TAD

## 🔌 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
