🔌 Function

Sits under the nut and bites into the surface so the joint resists loosening under vibration.

⚠️ Common Signs of Failure

• Nut backing off, leaving the joint slack
• Teeth flattened, so the washer no longer bites
• Washer cracked, distorted or dished
• Rust staining running from the joint

🛠️ Service Notes

• Hexagon nut 984990 shares the same two kits and the same 27 applications, so the two are fitted together. Order the pair, or take kit 3808886 or 3808887 which contains both
• A toothed washer is a single-use item once the teeth have been flattened, so fit a new one rather than reusing it

📦 Condition

• Genuine Volvo Penta part
• Brand new
• Supplied in original or equivalent packaging
