## 🔌 Function

Acts as a sprung disc that keeps load on the assembly it sits in, taking up clearance as parts settle.

## ⚠️ Common Signs of Failure

-   Disc cracked, flattened or set
-   Fretting marks on the faces either side
-   Fuel delivery or mechanism setting drifting
-   Corrosion on the disc faces

## 🛠️ Service Notes

-   Clamping ring 840854 also replaces 861067 and covers the same 23 D series applications, so the two came from the same earlier assembly and are best ordered together
