# 21044436 Flywheel Housing | Genuine Volvo Penta Part

## 🔧 Product Description

Brand-new genuine Volvo Penta flywheel housing machined or formed for use in the Volvo Penta TAD420VE flywheel and rear-engine housing. It supports and encloses the associated component while maintaining the specified bearing, sealing and mounting geometry.

## 🚤 Compatibility

Typically suits:

-   Volvo Penta TD420VE
-   Volvo Penta TAD620VE
-   Volvo Penta TAD420VE

-   **Engine Family:** TD, TAD

## ⚙️ Key Features

-   Genuine Volvo Penta housing
-   Correct bore, flange and mounting geometry
-   Maintains component alignment and protection
-   Designed for the original load and operating environment
-   Housing only; bearings, seals and hardware are separate unless listed
-   Engine type: Volvo Penta four-cylinder industrial diesel

## 🔌 Function

Supports, encloses or locates the associated engine or driven-equipment components while maintaining alignment and sealing interfaces.

## ⚠️ Common Signs of Failure

-   Cracks, impact damage or fluid leakage
-   Worn bores or damaged bearing seats
-   Distorted flange or sealing surface
-   Damaged threads or mounting points
-   Fretting, misalignment or repeated seal failure

## 🛠️ Service Notes

-   Clean both faces back to bare metal and remove every trace of old gasket and sealant before offering the housing up; trapped debris on this joint causes both leaks and misalignment
-   Locate the housing on its dowels and pull it down evenly, working outwards from the centre, in the sequence and to the figures in the workshop manual for your engine
-   Seal the joints where the housing meets the block and the sump exactly as the manual specifies — those corners are a common source of oil weeps
-   Renew the crankshaft rear seal while the access is open rather than refitting an old one, and check its running surface at the same time
-   Confirm the housing bore and face run true to the crankshaft before hanging a gearbox or drive on it; a housing out of alignment will destroy couplings and bearings
