## 📋 Kit Contents

-   1 x complete hydraulic steering-pump repair pack - Volvo Penta 21384615

## ⚠️ Common Signs of Failure

-   Pump is noisy or aerates the fluid
-   Internal seals are hardened or worn
-   Pump is being dismantled for overhaul

## 🛠️ Service Notes

-   Service kits are built for a specific engine family and serial-number range, and contents change between builds — confirm the kit against your engine's serial number before ordering
-   Check the kit against the job before you start and fit it complete; leaving out the parts that still look serviceable defeats the point of a kit
-   Renew every gasket, seal and O-ring supplied even where the old ones appear sound, and follow the tightening sequences and figures in the workshop manual for your engine
-   Record the work and the engine hours when the kit goes in, so the next service falls due at the interval Volvo Penta specifies for your engine
