## ⚙️ Key Features

-   Plain washer from the Inlet and Exhaust System group, 0.163 kg
-   Listed for seven D series engine applications

## 🔌 Function

Spreads the clamping load of its fastener across the joint face, so the bolt head does not dig into the parent material.

## ⚠️ Common Signs of Failure

-   Fastener losing torque and working loose in service
-   Washer found dished or cupped rather than flat
-   A fretting witness ring around the bolt hole
-   Corrosion or cracking where the washer sits

## 🛠️ Service Notes

-   Plain washer listed in the inlet and exhaust installation for D8 and D13 marine engines; at this size it is a load-spreading washer for a substantial fixing, not general hardware.
-   Fit a new one when the joint is disturbed — fixings in this area are heat-cycled and vibration-loaded, and a dished or scored washer lets clamp load fall away.
-   Check that both bearing faces are clean and flat before assembly, and do not substitute a general-purpose washer: thickness and grade are part of the joint design.
-   Tighten the fastener to the figure given in the workshop manual for your engine.
