# 21379172 Spring Pin | Genuine Volvo Penta Part

## 🔧 Product Description

Genuine slotted or coiled spring pin used to locate, retain or transmit movement in the Volvo Penta mechanical assembly that specifies part number 21379172.

## ⚙️ Key Features

-   Genuine Volvo Penta spring pin
-   Factory diameter, length and spring tension
-   Provides interference-fit retention
-   Used to locate a shaft, lever, gear or linkage
-   Application controlled by the assembly parts list for your engine

## 🔌 Function

The pin locates or retains the associated mechanical component through an interference fit.

## ⚠️ Common Signs of Failure

-   Pin loosening or walking out
-   Sheared or cracked pin
-   Excessive linkage play
-   Component misalignment

## 🛠️ Service Notes

-   Support the component solidly and drive the pin straight along its bore with a pin punch of the correct size — a pin started at an angle burrs the bore and locks up
-   Check the holes in the two parts line up and the bore is clean and free of burrs before you start
-   Fit a new pin rather than reusing one that has been driven out; a spring pin loses its grip once it has been collapsed and expanded
-   Drive it to the same depth as the original so it sits flush and cannot foul or catch a moving part
-   Where the pin retains a shaft, lever or roller, check the joint moves freely afterwards and that the pin is properly captive
