# 9998678 Gauge rod | Genuine Volvo Penta Part

## 🔧 Product Description

Genuine Volvo Penta special tool 9998678, listed at 0.962 kg and catalogued here as a dial indicator. Volvo's own special tools catalogue designates it a gauge rod — a fixed measuring rod rather than a dial gauge — and publishes its applications: thirty-two in all, D8A1-A MP and D8A4-A, the MDE 5/8 units and the TAD550GE to TAD873VE industrial range. Magnetic stand 9999696 is also listed in our range at 1.701 kg.

## ⚙️ Key Features

-   0.962 kg
-   Designated a gauge rod in Volvo's special tools catalogue, where our listing names it a dial indicator
-   Published for thirty-two applications across D8, MDE 5/8 and the TAD550-TAD873 industrial range
-   Magnetic stand 9999696 also listed in our range at 1.701 kg

## 🔌 Function

Gives a fixed reference length so a depth, height or protrusion can be checked against the figure the procedure specifies rather than judged by eye.

## ⚠️ Common Signs of Failure

-   Measuring end worn, bruised or picked up
-   Rod bent or bowed, so the reference length no longer holds
-   Corrosion or pitting on the measuring faces
-   Markings worn away or unreadable
-   Checks failing to repeat over the same feature

## 🛠️ Service Notes

-   Our listing calls this a dial indicator and Volvo's own entry calls it a gauge rod — confirm which the procedure needs before ordering
-   Keep the measuring end clean and undamaged; a bruised end shifts every check made with it by the same amount
