3804827 Short Block Core | Genuine Volvo Penta Part

🔧 Product Description

Core deposit for a shortblock, in the Engine group. It is the refundable charge raised against the old shortblock when the exchange unit is bought, and it comes back once the worn shortblock is returned. The line itself is an accounting entry rather than a part, so nothing ships against it on its own. Under Volvo Penta's core numbering the exchange unit it belongs to takes part number 3801827. We list that number as an exchange shortblock. The other shortblock cores here are 3804825, 3804826 and 3804828, and nothing published against them separates one from another, so order the number that matches the shortblock actually coming off.

⚙️ Key Features

• Core deposit line, not a shortblock you can fit
• Belongs with the exchange unit, part number 3801827
• Refunded when the old shortblock is returned
• Not separable from the other shortblock cores here, so order by part number
• Engine group

🔌 Function

As a line item it carries the refundable core charge on the exchange; the shortblock itself is the cylinder block built up with crankshaft, bearings, pistons and connecting rods, ready to take the head, sump and ancillaries off the old engine.

⚠️ 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
• Knock or rumble from the bottom end that hardens under load, with oil pressure down
• Heavy oil use and blue smoke, with pressure blowing back through the breather
• Poor or uneven compression, hard starting and lost power
• On strip-down, scored or ovalled bores, picked-up bearing shells, or a cracked or distorted block

🛠️ Service Notes

• The charge is refunded when the worn shortblock is returned, so keep the old unit and send it back rather than scrapping it
• Ordering this number on its own supplies no part - it goes on the order beside the exchange unit, part number 3801827
• The head, sump, pumps and ancillaries transfer across from the old engine, so inspect and renew those before they are bolted to the exchange shortblock, and fit a full gasket set with fresh oil and filters

📦 Condition

• Refundable core deposit - not a physical part
