# 21339645 Set Screw | Genuine Volvo Penta Part

## 🔧 Product Description

Genuine Volvo Penta internal set screw used in the DPI-A valve and gearhousing assembly. It secures the pressure-control or shift-valve components within the housing and must be matched by drive serial because the valve guide, sealing sleeve and housing revisions are position-specific.

## ⚙️ Key Features

-   Illustrated valve-housing

-   Engine type: Volvo Penta DPI-A marine sterndrive propulsion system

## 🔌 Function

Secures or sets the assigned valve component so hydraulic pressure and shift functions operate within specification.

## ⚠️ Common Signs of Failure

-   Shift becoming slow, hesitant or failing to engage cleanly
-   Hydraulic pressure fault or an unstable pressure reading in the drive
-   Oil weeping from the valve housing area
-   Screw found backed off or unlocked during strip-down
-   Thread or seating face found damaged so the setting will not hold

## 🛠️ Service Notes

-   Renew the guide sleeve and sealing sleeve at the same time - refitting old sleeves is the usual reason a repaired valve leaks again
-   Match by drive serial number, as the valve guide, sleeve and housing revisions are position specific
