## ⚙️ Key Features

-   Genuine Volvo Penta structural engine-mounting stay
-   Used in D8 marine propulsion anchorage assemblies

-   Approximate component weight: 8.8kg
-   Engine type: 7.7L inline six-cylinder common-rail marine diesel

## 🔌 Function

Braces the engine and reversing-gear mounting structure so propulsion torque and vibration are transferred through the intended load paths without disturbing shaft alignment.

## ⚠️ Common Signs of Failure

-   Engine or gearbox movement under load
-   Persistent driveline vibration
-   Cracking around the stay or mounting holes
-   Fretting, loose fasteners or elongated bolt holes
-   Coupling or shaft-alignment changes

## 🛠️ Service Notes

-   A stay supports a component and braces it against engine vibration, so offer it up and get the fasteners started before anything in the joint is finally tightened
-   Leave all the fasteners finger tight, then tighten them in the order the manual gives, so the stay is not used to drag a misaligned component into position
-   If the stay will not line up without strain, find out why rather than pulling it up on the bolts — a stay under tension feeds that load straight into the bracket, casting or pipe it is meant to support
-   Renew a stay that is cracked, bent or has elongated fixing holes instead of straightening it; its whole function is stiffness, and a distorted or loosely held stay transmits vibration rather than resisting it
-   Use the specified fasteners with their washers, tightened to the figures in the workshop manual for your engine, and recheck them whenever the component the stay supports is disturbed
