# 978993 Split Pin | Genuine Volvo Penta Part

## 🔧 Product Description

Genuine Volvo Penta split pin weighing 0.091 kg. No diameter or length is published for it, and the other split pin in this run, 979874, is a separate part at 0.011 kg, so weight is no guide to size - order by part number or match the old pin.

## ⚙️ Key Features

-   0.091 kg
-   Single-use mechanical locking pin
-   Diameter and length are not published - order by part number
-   Split pin 979874 is the other pin listed here

## 🔌 Function

Passes through a drilled shaft or the slots of a castellated nut and is splayed open, so the nut cannot rotate off under vibration.

## ⚠️ Common Signs of Failure

-   Castellated nut found loose or backed off along the thread
-   Pin legs cracked or snapped where they were bent over
-   Pin missing altogether, with a bright fretted witness mark at the hole
-   Pin hole in the shaft worn oval or elongated
-   Corrosion seizing the pin in its hole so it breaks up on removal

## 🛠️ Service Notes

-   Fit a new pin every time - one that has been opened and closed once is work-hardened and will snap
-   Splay both legs fully back and check that nothing rotating can catch them

-   Genuine Volvo Penta part
