3804497 Short Block Core | Genuine Volvo Penta Part

🔧 Product Description

Refundable core deposit raised against the exchange shortblock on Volvo Penta part number 3801497, listed under Engine. It is an accounting line rather than a fittable part: the charge goes on when the exchange shortblock is supplied and comes back off when the old shortblock is returned, and nothing is shipped against the deposit itself. Five consecutive shortblock deposits run from 3804497 to 3804501 with nothing in the record to tell them apart, so the paired unit number is the only safe guide.

⚙️ Key Features

• Refundable core deposit, not a fittable part
• Paired unit number 3801497
• Nothing ships against this line
• Credited back when the old shortblock is returned
• Listed under Engine

🔌 Function

Carries the refundable core charge on the outgoing shortblock rather than doing any mechanical work itself. A shortblock is the block, crankshaft, pistons and connecting rods supplied without the cylinder head.

⚠️ Common Signs of Failure

• This is a deposit line and has nothing to fail in itself; the signs below are what normally condemns the shortblock being exchanged
• Bottom-end knock under load, deepest when the oil is hot
• Oil pressure low at idle, with bearing material showing in the filter or sump
• Blow-by heavy at the breather and oil consumption climbing
• Bores scored or worn ridged, and crank journals marked, once the engine is opened up

🛠️ Service Notes

• The charge is credited back once the old shortblock is returned through the dealer; it has to go back complete and rebuildable, and a stripped, cracked or seized-solid shortblock can be refused or the credit cut.
• Ordering this number on its own supplies no part. It only makes sense raised alongside exchange unit 3801497, so confirm that unit is obtainable and check its exact designation before quoting.
• This part of the block runs engine, base engine, longblock and shortblock deposits side by side; those are four different builds of exchange unit and the deposits are not interchangeable, so match the wording as well as the number.

📦 Condition

• Refundable core deposit - not a physical part
