⚙️ Key Features

🔌 Function

Provides a controlled spring load in the fuel system assembly, holding a component seated or preloaded against pressure.

⚠️ Common Signs of Failure

• Fuel weeping from the assembly the disc loads
• Pressure or delivery falling away from its setting
• Disc found cracked, flattened or set on strip-down
• Fretting marks or bright wear on the seating face
• Assembly loose or rattling when it should be under load

🛠️ Service Notes

• The number it replaces, 861067, also maps to gasket 870581 listed here — the old number covers more than one current part, so you may need both to make the joint up
• Renew the disc rather than reusing a set one; a spring disc that has lost its height will not hold the seat
