# 17487259 Flywheel Housing | Genuine Volvo Penta Part

## 🔧 Product Description

This genuine Volvo Penta flywheel housing is a machined structural housing or closure component used in the dual-PTO flywheel/transmission housing and lower-gear assembly. It is manufactured to the original Volvo dimensional, material and interface requirements so the serviced assembly retains its designed alignment, sealing, load capacity and operating reliability. In service, it forms the rear engine structure for the dual-PTO lower-gear and transmission-housing arrangement. Selection must be confirmed by OEM part number 17487259, the exact engine/product model, serial number and installed configuration.

## 🚤 Compatibility

Typically suits:

-   Volvo Penta TAD1170-72VE

-   **Engine Family:** TAD

## ⚙️ Key Features

-   Genuine Volvo Penta OEM flywheel housing
-   OEM part number 17487259
-   Measure bearing bores and sealing faces, check alignment and cracks, renew gaskets/seals and tighten the housing in the specified sequence.

## 🔌 Function

Forms the rear engine structure for the dual-PTO lower-gear and transmission-housing arrangement. Measure bearing bores and sealing faces, check alignment and cracks, renew gaskets/seals and tighten the housing in the specified sequence.

## ⚠️ Common Signs of Failure

-   Cracking around mounting bosses or the bellhousing flange
-   Oil leakage at the rear main seal or housing joint faces
-   Wear or damage to the spigot register affecting alignment
-   Driveline vibration traced to housing misalignment
-   Elongated, stripped or damaged mounting threads

## 🛠️ 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
