🔌 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

• Assembly slack or rattling where it should be preloaded
• 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
• Fit a new disc rather than reusing a flattened one, and check the mating faces for fretting
