3801703 Longblock Exch | Genuine Volvo Penta Part

🔧 Product Description

Genuine Volvo Penta remanufactured long block for the D6 F-series, weighing 449.056 kg and listed for nine applications - the D6-300, D6-330 and D6-370 engines in A, D and I forms. 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 arrives; the fuel, induction and exhaust equipment either carries over or is ordered under its own reman numbers. The catalogue lists this block in the same engine package as cylinder head 3801887, injectors 3801857 and 3801858 and turbocharger 3802152. 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

• Find and fix what destroyed the old block, oil supply and coolant condition above all, before the new one is run
• Core deposit 3804703 carries the exchange fee and is refunded when the old block goes back
