23710836 Plain Washer | Genuine Volvo Penta Part

🔧 Product Description

Genuine Volvo Penta plain washer weighing 0.001 kg. It supersedes part number 20773400 and covers its eight TAD series engine applications.

⚙️ Key Features

• Plain washer
• 0.001 kg
• Supersedes 20773400, catalogued earlier as a washer
• Covers eight TAD series engine applications

🔌 Function

Spreads the clamping load of the fastener over a wider area, protecting the surface underneath and helping the joint hold its torque.

⚠️ Common Signs of Failure

• Fastener no longer holding torque
• Washer found dished, cupped or bent
• Bright fretting or bedding marks on the face
• Corrosion or pitting reducing the section
• Surface under the washer found indented or picked up

🛠️ Service Notes

• Small plain washer for the exhaust manifold, turbocharger and alternator bracket fixings on the TAD range; it supersedes an earlier washer reference, so check the number if you are ordering from an older parts record.
• Fit new washers whenever these joints are disturbed — repeated heat cycling work-hardens and dishes a washer, and a dished washer will not hold clamp load.
• Discard any washer that is blued, cupped or scored on its bearing face rather than putting it back.
• Tighten the fastener to the figure given in the workshop manual for that joint; the washer's thickness and grade are part of the joint design, so use the genuine part.
