⚙️ Key Features

• Isolation washer
• 28 applications across D series engines and IPS installations
• Marine Propulsion isolating component
• 4 used per assembly

🔌 Function

Isolates the fastener from the component it clamps, breaking the electrical or metal-to-metal path across the joint while still spreading the clamping load.

⚠️ Common Signs of Failure

• Corrosion at the joint the washer should be isolating
• Washer cracked, crushed or split
• Continuity found across a joint that should be isolated
• Fastener loosening as the washer compresses

🛠️ Service Notes

• Fit isolation washers as a complete set at a joint — one missing or crushed washer defeats the isolation
• Do not overtighten, and check across the joint after assembly to confirm the isolation is intact

📦 Condition

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