3801615 Longblock Exch | Genuine Volvo Penta Part

🔧 Product Description

Genuine Volvo Penta remanufactured long block for the D11B1-A MP, D11B2-A MP, D11B3-A MP and D11B4-A MP, weighing 800 kg - the heaviest of the seven long blocks listed here. Volvo Penta defines a long block as a cylinder block assembly with pistons, connecting rods, crankshaft, camshaft, cylinder heads, rocker mechanism, oil pan and valve cover, so that is what is in the crate; the induction, fuel and exhaust equipment carries over from your engine or is ordered under its own reman numbers. The catalogue lists it as one package with cylinder head 3801534, unit injector 3801433, turbocharger 3801526 and circulation pump 3801619. Supplied on exchange, so a core fee is added to the invoice and refunded once the worn block is returned, and you may keep the old one until the new block is in and the engine is running again.

🔌 Function

Replaces the whole reciprocating and rotating heart of the engine as one assembly, so a worn or damaged bottom end can be changed out without rebuilding it in the boat.

⚠️ Common Signs of Failure

• Oil pressure low or falling away when hot
• A deep knock from the bottom end that rises with load
• Heavy breathing from the crankcase and oil pushed out of the filler or breather
• Metal glitter in the oil or debris in the filter
• Scored bores, worn shells or a cracked block found on strip-down

🛠️ Service Notes

• Find and fix what destroyed the old block, oil supply and coolant condition above all, before the new one is run
• Core deposit 3804615 carries the exchange fee and is refunded when the old block goes back
