20511322 Washer | Genuine Volvo Penta Part

🔧 Product Description

This genuine Volvo Penta washer is an OEM service component used in the Breather / Inlet Assembly Washer. It is manufactured to the original Volvo Penta dimensional, material and interface requirements for the documented Volvo Penta 4-litre TAD4 industrial diesel application. Technical identification: Sealing/support washer used at the crankcase-breather pipe connection. In service, it distributes fastener load, controls spacing or provides the specified locking/sealing interface at the joint. Selection must be confirmed by OEM part number 20511322, the exact model/product number, serial number and installed assembly configuration.

⚙️ Key Features

• OEM part number 20511322
• Technical distinction: Sealing/support washer used at the crankcase-breather pipe connection

🔌 Function

Distributes fastener load, controls spacing or provides the specified locking/sealing interface at the joint. Confirm dimensions, thread and strength class, inspect mating threads/contact faces and tighten to the Volvo Penta torque and locking specification.

⚠️ Common Signs of Failure

• Oil mist or weeping at the crankcase-breather pipe connection
• The joint fastener found loose at service
• Oily residue collecting below the breather pipe
• On removal, the washer flattened, cracked or with its sealing face bedded through

🛠️ Service Notes

• Check you are fitting the same type of washer that came out — plain, hardened, sealing and locking washers are not interchangeable, and the wrong one either fails to seal or fails to hold
• Treat sealing washers on fuel, oil and coolant unions as single-use; they seal by deforming onto the faces, so a used one will not seal reliably a second time
• Clean the seating faces and make sure the washer sits flat and square, fully under the head or nut, before tightening — a washer trapped on a chamfer or edge will crush unevenly
• Tighten the fastener to the figure given in the workshop manual for your engine, and account for every washer on reassembly so none is left loose inside a housing or the engine bay
