# 3849545 Splined socket (large) | Genuine Volvo Penta Part

## 🔧 Product Description

Volvo Penta service tool 3849545, weighing 0.660 kg. Our listing recorded nothing but the weight; Volvo's own special tools catalogue names it properly - it is the large splined socket, and it is listed for the IPS-A to IPS-F drive units. Tool 885880 is the small splined socket for the same six drives, so large and small is the distinction to order on.

## ⚙️ Key Features

-   The large splined socket of a pair, with 885880 the small one
-   Listed for the IPS-A to IPS-F drive units
-   0.660 kg
-   Genuine Volvo Penta special tool

## 🔌 Function

Engages the splined nut or shaft on its full spline form, so a high-torque fastening can be released and set without damaging the splines.

## ⚠️ Common Signs of Failure

-   Splines worn, rolled over or chipped
-   Socket rocking on the nut instead of seating fully
-   Drive square spread or rounded
-   Cracks at the drive end or a section change

## 🛠️ Service Notes

-   Order the large or the small socket by size - 3849545 is the large one, 885880 the small - since both are listed for the same IPS-A to IPS-F drives
-   Mounting tool 885604 is listed for the same six drives and belongs with the same body of work
