947071 Tab Washer | Genuine Volvo Penta Part

🔧 Product Description

Genuine Volvo Penta tab washer for the TD60B PP, weighing 0.002 kg and listed for 46 applications across the TWD, TID, TD and TAD series. It supersedes 3828663 and 848554 — both of those numbers are also replaced by hexagon nut 946330 in this run, which usually means the two current parts answer the old number together rather than either one on its own.

🚤 Compatibility

• Engine Family: TWD, TID, TD, TAD

⚙️ Key Features

• For the TD60B PP
• 0.002 kg
• Supersedes 3828663 and 848554
• 46 applications across TWD, TID, TD and TAD series engines

🔌 Function

Locks a nut or bolt mechanically, with a tab bent up against a flat of the fastener once it is tightened.

⚠️ Common Signs of Failure

• Fastener found loose with the tab already flattened
• Tab cracked or broken off at the bend
• Washer bedded, dished or fretted against the joint
• Locking tab bent more than once and now work-hardened

🛠️ Service Notes

• Tab washers are single use — a tab bent up and flattened once will crack the next time
• Bend the tab hard against a flat of the fastener, not a corner
• Check whether nut 946330 is needed too; both current parts replace the same old numbers
